The Importance of Your Vehicle’s Powertrain

Why is your vehicle’s powertrain so important? Your vehicle relies on it to keep it going. The main functions of your vehicle is controlled by the powertrain. If the powertrain is not working properly then your vehicle is at high risk for breaking down.

Powertrain Basics

The powertrain is the mechanism that transmits the drive from the engine to the axle. The components of the powertrain are the engine, driveshaft, rear axle, transmission, and differential. These parts all work together to connect to the drivetrain. The powertrain generates the power between the engine and the transmissions to generate the power to the wheels also known as the drivetrain. These components work together to make the vehicle run properly.

Powertrain Parts

The powertrain consists of the engine, driveshaft, rear axle, transmission, and differential.


It is the heart of your vehicle causing it to run.The engine is the central of the vehicle, it takes fuel, air, and spark to cause the horsepower that makes your vehicle run. The piston goes up and down the crankshaft (the pedals and chainwheels) to power the car by turning into a circular motion.


The driveshaft, also known as, the propeller shaft, is a long rotating shaft that bridges the gap between the engine and the transmission. The drive shaft transmits torque to connect other components of a drivetrain. The rear axle is a central shaft for a rotating gear. The driveshaft causes the wheels to move.

Rear Axle

The wheels of an vehicle is connected to an axle. The rear axle is a central shaft for a rotating gear. This is how the wheels turn in different directions.


The transmission provides the power through the gearbox to provide gear and torque conversions from a rotating power source. Within the transmission the gearbox and the clutch transmits and converts the power between the engine and to the wheels. Once it converts to the wheels, it allows the rotation between the axles causing the wheels to move at different directions. The clutch engages or disconnects with the engine from the gears, so they can shift in the various directions such as: shift up, down, or neutral. A low gear produces more force at lower speeds. A high gear produces less force at high speeds.

Types of Transmissions

  • Manual
  • Semi-automatic
  • Duel Clutch
  • Continuously Variable Transmissions


Located on the center of the axle is the differential. The differential drives a pair of wheels while allowing them to rotate at different speeds. The differentials split the power out between two wheels, so they can go in different speeds.

Powertrain Engines

A powertrain engine offers many advantages. The powertrain engine will include all of the parts you need for the vehicle to run properly. Buying a complete powertrain engine can prevent problems that buying different parts separately could cause. When buying a complete powertrain engine it will include the main engine, driveshaft, rear axle, transmission, and differential. This should help everything run smooth.

Drivetrain VS Powertrain

The main difference between the drivetrain and the powertrain is that the powertrain is the part that consists of engine and everything that works together to make it run and the drivetrain is the wheel and the gears. The drivetrain refers to all of the parts that is needed to propel the vehicle excluding the engine, it includes the steering column and the driveshaft and the powertrain refers to all of the parts that make the vehicle run including the engine but not the engines accessories. 


What Is Your Powertrain?
The part of the vehicle that transmits the drive of the engine from the axle.

What Does It Mean When Your Powertrain Light Come On?
It comes on when there is a problem with the engine or the transmission. It also is warning you to get it fixed immediately and be cautious when driving since further problems can persist once you are driving. If you see your powertrain light come on contact Bimmer Repair for assistance.

What Is A Powertrain Malfunction?
When there is a problem with the engine, transmission, or drivetrain.

How Much Does It Cost To Fix A Powertrain?
Between $450-$1,630. The cost of labor should be between $45-$125. The cost of a replacement for a powertrain or powertrain parts can be between $400-$1,500.

How Does A Powertrain Warranty Work?
It usually covers the transmission, engine, and drivetrain. If these parts are damaged or defective within the time frame within the warranty the manufacturers will repair or replace these items.

It is important to know about the different parts of a powertrain. It also is important to know what the difference in the powertrain and drivetrain is so when you buy a warranty you know what is included in a powertrain and in a drivetrain, some warranties may only include parts included in a powertrain. Knowing some main functions of your vehicle can help you have a frame of reference for your vehicle and it helps you take better care of your vehicle.

Is Your Vehicle Ready for Winter?

A Car Swerved Off the Road Into Snow

It Pays to Be Prepared! Regular Maintenance Can Help You Avoid Winter Roadside Emergencies.

Winter is coming, as you can tell from the rapidly dropping temperatures and shortened days. Now is the time to prepare your vehicle, especially if you are planning on taking a long trip this Christmas. Texas weather is difficult to predict in the best of times, and winter is no exception. Thankfully, winterizing your car doesn’t have to interrupt your busy schedule or break the bank. With a little vehicle maintenance and an emergency car kit, you’ll be set to brave whatever the season throws your way! 

How Do I Take Care of My Car in the Winter?

Frigid weather can produce a serious strain on your vehicle. That means it’s time to winterize your car. What does winterizing your vehicle mean? That’s just a fancy way of saying to prepare your car for winter conditions: frigid air, freezing condensation, and additional driving challenges.

The cold air takes a considerable toll on your battery life. Freezing temperatures prevent your battery’s internal chemical reactions from operating efficiently, thus the output is seriously reduced. Try to park your car indoors as often as possible during the winter. If you can’t, leave your car in a place protected from the wind. This will slow the gradually drain of power from your battery, though you may need to get it juiced up eventually. 

Winterizing the car battery is just one step of preparing your vehicle. Be sure your car fluid levels (especially your antifreeze) are sufficient for winter travel. A slushy highway is not the place to discover your radiator is fresh out of coolant. It’s also essential that you check the treads on your tires. Bald tires can make winter travel feel more like skiing than driving.

Finally, make sure you keep an emergency car kit in the back seat or trunk for emergencies. You’ll want it in an easy-to-access location in case of an accident. We’ll go over what to include in your kit in a just little while.

Performing Winter Car Maintenance on Engine

Most Car Maintenance Checkups Can Be Completed Within a Couple Hours or Less.

Of course, your local vehicle maintenance service will be more than willing to prepare your car for the road ahead. A fresh oil change and a good drink of antifreeze will make sure your performance doesn’t sag during the cold weather. If you notice that your battery is struggling every time you turn the engine, consider asking your mechanic for a recharge (or purchasing a charger). You could save yourself a considerable amount of money that you would have spent on a new battery. 

If you have concerns about the health of your tires, your mechanic will let you know whether or not it’s time to consider replacements. Be sure to mention if you’ve had any issues with your car heating system. Better a little maintenance now than a broken heater a month from now.

Above all, make sure your brakes are working properly. That means checking your brake fluid for color and texture. Dirty brake fluid can make rapid stops a challenge.

Winter Car Maintenance Checklist

  • Battery Test and Recharge
  • Fluid Check
  • Brakes Check
  • Heating System Check
  • Tire Exam
  • Spark Plug Exam
  • Belt Check
  • Hoses Check

What Happens if Car Maintenance is Neglected?

Many drivers put off basic maintenance until their vehicle shows clear signs of distress. This accelerates the degradation of the engine and other car parts, and is a categorically bad idea. If a driver waits long enough, they may start to experience some of the following problems.

  • Reduced engine performance
  • Increased difficulty steering/maneuvering
  • Engine overheating
  • Limited braking capabilities
  • Battery failure
  • Engine power loss
  • Burning smells
  • Fluid leaks
  • and more

While car failure is typically a gradual process, disregard for basic maintenance requirements is the fastest way to destroy a once-healthy vehicle. In the winter time, harsh weather takes an even faster toll on car performance. If you have any doubts about the safety of your vehicle, it’s always best to talk to a qualified mechanic. 

What Should I Keep in My Car for Winter?

Attaching Jumper Cables to a Car Battery

Hopefully You Won’t Need Them, But Be Sure to Pack Jumper Cables in Your Car Kit!

The Department of Motor Vehicles may not be your favorite place to visit, but they do have a great list of items to include in your winter emergency car kit! They include:

  • A Tire Gauge
  • Road Flares
  • Lug Wrench
  • Car Jack
  • Flashlight
  • Small Shovel
  • Coolant
  • Ice Scraper
  • Sand or Cat Litter
  • A Blanket (a must)
  • Gloves
  • Snacks
  • and a Warm Hat.

To this list, we recommend you add jumper cables, a phone charger, and a signal booster (for rural trips). During emergencies, supplies are invaluable, but contacting 911 or roadside assistance generally takes precedence. If you can’t get a signal, try making a “HELP” sign (or packing one) from brightly colored materials.

The Symptoms of a Bad Oil Filter

An Auto Mechanic is Holding an Old, Dirty Engine Oil Filter

Learn What the Symptoms Are for a Bad Oil Filter.

Want your BMW’s engine to be in the very best condition? The best way for this to happen is to get your oil changed. While the oil lubricates the engine, the oil filter ensures that contaminants are being filtered out of the engine’s oil. When the oil filter isn’t in great condition, the performance of your BMW can suffer. Knowing what the symptoms of a bad oil filter are can prevent any unwanted issues for your car. Below are some of the symptoms of a bad oil filter in your BMW.

What Are the Symptoms of a Bad Oil Filter?

  • Car Sputtering: One of the biggest symptoms of a bad oil filter is when your car is sputtering. Usually, when the oil filter is clogged, which in turn makes it hard for the car to release oil. This can cause problems with the speed of your car, so it’s important to take your car in when you notice any sputtering.
  • Grinding Sounds: When you hear any type of grinding noise in your car, it’s almost always metal on metal grinding against each other. This is another issue with the oil filter being clogged; when the oil filter is clogged it can’t produce oil to lubricate the engine, which causes the metal on metal to grind against one another.
  • A Drop in the Oil Pressure Gauge: The great thing about cars now is that we are able to monitor our oil on an oil pressure gauge. If you have noticed that there has been a dramatic drop in the reading of your oil pressure gauge, something must be wrong with the filter.
  • Exhaust Is Dirty: Have you noticed that the exhaust coming from your car is dirty or black? Have you been smelling burning oil? These are great reasons to take your BMW in. The issue is with the filter or there is a clog in the oil system.

The best way to ensure your car is in the best shape is to get regular tune-ups. At Bimmer Repair we can provide oil changes in Dallas, TX by using Valvoline SynPower SAE 5W-30 for your BMW. Give us a call at 469-471-6433 to make an appointment.

What Are the Signs of a Bad Transmission? Find Out If You Need Transmission Repair!

There are many components in our cars that make it possible to run. Every part works together to ensure you can turn on your car and drive it to wherever you need to go. One of the most important parts in any car is a transmission. The transmission is able to power the engine so your wheels can go at the speed you need. There are two types of transmissions, manual and automatic; while they work differently, they can both become damaged over time. If you have never worked with cars before, it can be hard to know when you have a bad transmission. Some signs of a bad transmission include the car stalling or your gears are grinding. If you have been experiencing any of these issues, with your car transmission, you can call Bimmer Repair at 469-471-6433 for transmission repair in Dallas, TX.

What Causes Car Transmission Problems?

There are several things that can cause issues with your car’s transmission. One of the most common is when there is a leak in the system. A leak typically occurs when there are damages to the transmission seals or driveshaft. In regards to manual cars, the biggest problems you will see with transmissions if there are issues with the clutch. This can entail hesitation when shifting, a faulty clutch, a problem with clutch linkage, or a dragging clutch. If you are ever having issues with your car, feel free to contact us. We can determine if you need transmission repair or some other service for your car.

Can You Replace Transmission Fluid?

When it comes to the job of your transmission fluid, it is extremely important in the health and performance of the transmission.

When the transmission fluid isn’t replaced or flushed out, it can cause serious damage to the transmission. Knowing when you need a transmission flush, will help you prevent your transmission from becoming damaged.

How Do You Know If My Transmission Is Going Out?

In order to avoid a complete transmission rebuild, it’s essential to know when your transmission might be going out or failing. Some of the biggest signs that your transmission is going out are leaks in the transmission, delays when you shift, its harder for you to shift, or you feel the transmission slipping. If you notice any type of problem that you think is caused by a damaged transmission, please call Bimmer Repair at 469-471-6433.

Leaking Fluid: What it Could Mean For Your Car

Radiator Fluid

Keeping Your Car’s Fluids in Balance Ensures Proper Functionality and Safety.

Fluid leaks don’t always spell doom for your car. For instance, many cars drip clear condensation from their tail pipes that’s just a part of your car’s normal function. However, colored leaking fluid should be taken seriously and addressed as soon as possible. Here is a short guide on identifying potential problems indicated by a leak. 

Leak #1: Automatic Transmission Fluid

This liquid helps your automatic shifting vehicle transition between gears as you speed up and decelerate. A leak from your transmission will typically appear red or pink, and should be addressed quickly. Red or pink fluid can alternatively come from your power steering, so it’s best to let a mechanic perform the inspection.

Leak #2: Radiator Fluid

Radiators are a common source of leaking, so you shouldn’t be too surprised if you spot antifreeze leaking from your car. Antifreeze (a coolant) will generally be green, but on occasion it can be orange or pink. Low coolant levels can cause engine overheating and reduced power levels. Left alone for too long, a coolant leak can even lead to total engine shutdown.

Leak #3: Motor Oil

Oil leaks are one of the most common car health problems. As oil ages, it will transition from light brown to dark brown and finally black. Oil leaks can originate in several parts of your car, and while the issue may be common, it’s still important to have your car checked when you spot a leak.

Leak #4: Brake Fluid

Yellow brake fluid powers your car’s braking system and protects you when you need to come to quick stop. The fluid will feel a little oily and be of a medium thickness. If you think you might have a brake fluid leak, get your car to the mechanic as soon as possible (even if you have to have it towed).

Unless you’re a certified professional, it’s wise to let a professional handle any of these problems. If you’ve spotted leaking fluid in or under your car, you can talk with our team at 469-471-6433. You can also schedule your regular car checkup!

Burn Out: When You Don’t Get That Oil Change

Pouring in New Oil

Getting an Oil Change Protects Your Engine and Ensures Better Performance.

Oil is the lubricant that keeps your engine running smoothly. Without oil, your engine couldn’t function for long, yet many car owners fail to have their oil replaced in timely manner. Here are three of the serious consequences you might experience if you don’t get that oil change in time.

Phase #1: Lowered Efficiency

When your car is designed for maximum driving capability, it’s a sad twist of fate when it begins to feel sluggish. That’s what happens when your vehicle goes too long without an oil change. As oil circulates throughout your engine, it absorbs dirt and other particles to protect your performance. Oil eventually draws in too much sludge too be effective, which leads to our second phase.

Phase #2: Overheating & Power Loss

Left alone for an extended time, dirty oil will no longer be able to draw heat away from your engine. Your vehicle will slowly start to overheat, until your engine reaches a temperature threshold where it can’t continue to operate. You might experience sudden partial or complete power loss. If car owners still continue to ignore these warning signs, the third phase of consequences is inevitable.

Phase #3: Warping & Complete Engine Failure

Without good oil, engine parts start to warp from the excess heat. This leads to further inefficiencies in your car’s driving performance, until parts simply start to fail. Complete engine failure is the ultimate result, and many car owners are forced to replace their engine or sell their vehicle.

Getting an oil change only takes about 15 minutes, but superior performance and safety for your vehicle is worth the trip to your service provider. For more information about your engine or oil changes, you can talk with one of our technicians at Bimmer Repair. Give us a call at 469-471-6433.

Ensure High Performance: Changing Out Old Tires

Don’t let your driving experience be held back by worn out tires. Changing out your tattered tires not only ensures that your car achieves its maximum driving ability, it also keeps you and your family safe. If you’re wondering whether or not it’s time for changing out old tires, here are a few tricks to help you decide.

Man Checking Tire

Ensure Your Tires are Safe to Drive on. Use these 3 Tire Tests.

The Classic Penny Test

You’ve probably heard of this one because the penny trick is a tried and true method of spotting bare treads. Take a standard penny and insert it into the thread of each of your tires. Is Abraham Lincoln’s head partly or completely hidden away? If you answered “yes”, that tire’s tread is perfectly fine. If Lincoln’s head doesn’t disappear at all, it’s time to change out your tire.

Sidewall Exam

When examining your tires, your tread is just one of the parts you need to inspect. Take a look at the sidewall of each of your tires. Smooth sidewalls indicate healthy tires. Watch out for any blisters or lumps, however, as these indicate a blowout risk. If you see these spot either of these signs, make sure you talk to your dealer about getting the tire replaced.

Bar Test

Your tire manufacturer is constantly looking for ways to keep your vehicle safe. Some manufacturers include special indicators on your tires to tell you when to replace them. When you next examine your tread, look for bars appearing perpendicular to your tire tried. These start to appear as your tread becomes worn. If you see many of these bars, start looking for a tire replacement.

Use these tests to ensure your car is operating to its maximum potential. For more questions about changing out old tires, talk to us at Bimmer Repair. Call 469-471-6433.

Areas for Spring Car Maintenance

Spring Car Maintenance

Spring Car Maintenance Enables You to Take to the Roads with Confidence.

As winter relinquishes its hold, the approach of spring inspires drivers everywhere to take to the roads more often. With summer just over the horizon, you’ll want to make sure that your vehicle is ready for the driving season. Whether you plan to stay close to home or strike out for parts unknown, make sure to attend to these areas of spring car maintenance.

Under the Hood

First and foremost, you’ll want to make sure to get your oil changed. Even if you haven’t accumulated 3,000 miles, you should replace the oil every three months or so. All of your fluids deserve to be checked, especially your antifreeze, which needs refreshment every couple of years. Lastly, your hoses and belts deserve inspection. The cooling system hoses warrant special attention, as they can deteriorate from within.

Beneath the Vehicle

You should check your brakes thoroughly as part of seasonal maintenance, including the drums, lining, and rotors. Your struts and shocks should have no signs of physical damage, such as rust, leaks, or dents. If any fluids leak from beneath your vehicle, take it in for a professional look.

Vehicle Exterior

Several aspects of your BMW’s exterior deserve a review with the changing season. Take a good look at each of the following, and for any issues, contact Bimmer Repair.

  • Wiper Blades: Replace every three months.
  • Tires: Tread depth, uneven wear, under or over-inflation.
  • Paint Damage: Chips and minor damage can worsen quickly.

Regular Auto Maintenance for Your BMW

Your BMW is one of your most important investments. You put a lot of time and money into it, and so its care is also extremely important. That is why you should never put off those little maintenance tasks that so many people ignore when it comes to their auto care. Instead, keep up with that regular auto maintenance that your auto shop recommends.

Don’t Let Regular BMW Maintenance Slide

Tech with Clipboard Checking Car

Don’t Neglect Regular Auto Maintenance for Your BMW.

Basic auto maintenance does not mean repairs. Rather, it means those little things that are recommended by all auto shops, but that people too often don’t do. So many of these things, like checking tire pressure, having the oil changed regularly, and having a tune up every few thousand miles, are ignored.

Oil changes are a necessary part of your car’s health. So, have your oil changed as often as is necessary according to the mechanic that you trust. Even if you don’t drive your car that much, do it to extend its life. Check your tire pressure often, and have your tires rotated when you go to your auto shop. Because it’s not easy for a busy, working person to find time to go to the mechanic, schedule your maintenance services ahead of time so that you can fit the time into your own schedule more easily.

These little things that are part of regular auto maintenance are more important than you might think. Keep your BMW in good health and bring it to Bimmer Repair in Dallas, TX. Call us at (469) 471-6433 to make your appointment today.
