As mentioned in our previous blog, transmission flushes are a great minor maintenance task to have performed on your car to prevent major repairs. In most cases, getting a flush every 30,000 miles will be sufficient but in some cases, you will need to have this done sooner. If you are not sure when you will need to get this repair done, there are five common signs to look out for that are indicators you will need a transmission flush. No matter what kind of car you have whether it’s a Mercedes, Porsche, or BMW vehicle, these five signs are things you should keep an eye on.

Transmission Grinding or Strange Noises

If you are wondering if your transmission is contaminated with dirt, sludge, and grease you will notice that it will show symptoms similar to inadequate levels of transmission fluid. One of these signs is if you start to hear grinding or strange noises while driving. If you hear a strange noise then you will need to get a transmission flush and to make sure of this pullover and check the fluid level while the car is running by making sure the fluid color on the dipstick is bright red. If the color is brown or black then you will need a flush.

Problems Shifting Gears

If your transmission fluid contains a lot of dirt or sludge then you may have problems shifting gears as these contaminants will cause a sluggish response to the transmission. This sluggish response will result in your car changing gears too quickly or too late while driving. If you notice that this starts to happen to you while you drive, we recommend you call a professional repairs shop immediately for a flush.

Slipping Gears

When a transmission is too dirty, contaminants can interfere with the flow of fluid that helps develop pressure to hold appropriate gears while operating a vehicle. If you notice that your gears are starting to slip but the fluid levels are normal then you most likely have dirt and sludge built up in your transmission that needs to be flushed out.

Surging Of The Vehicle

Another sign that you may need a transmission flush is if you begin to notice your car surge or jump, forward or backward for no reason. This is usually caused by an inconsistent flow of clean fluid that is needed to ensure smoother operations of the gears and other parts of the transmission system. This inconsistent flow is caused due to dirt and sludge that will need to be flushed out.

Delay in Movement

If your transmission fluid has dirt, sludge, or grease in it then you will notice your vehicle stalling for a couple of seconds before moving after switching gears. If this happens then a transmission flush will help stop this from happening.

With any type of car, whether it is a Mercedes, Porsche, or BMW there is a slew of different types of parts and repairs for these parts. One of the biggest and most important parts of a vehicle is the transmission and depending on what you need to be repaired, it could get expensive. In order to prevent major repairs to be done, it is good to be diligent with your car’s maintenance and being on top of minor repairs. One minor maintenance task you can have done to prevent a big transmission repair is a transmission flush.

What is a Transmission Flush?

A transmission flush is a maintenance process where all of the oil in a transmission is removed and replaced with new oil. An experienced mechanic uses a special machine that runs cleaning solutions, as well as new oil, through your transmission that will push out any grime and sludge. This makes sure that your transmission is removed of debris and sludge that can hinder performance and cause more issues down the line.

What is a Transmission Change?

A transmission fluid change is a similar process to a flush but does not use a special machine. A change simply drains the fluid using natural gravitational forces. While this method helps clean up your transmission and drains about 20-40 percent of the total volume, it clean as good as a flush. Not all of the fluid in the transmission system is drained and it does not flush out contaminants within the oil. A change is normally used for a frequent maintenance or a quick fix to improving the life of your car’s transmission.

When it comes to repairs, whether it’s a flush or change, you will want to make sure that the work is done by a professional for optimal results.

Transmission Signs That Should Not Ignored

Transmission replacements are one of car owner’s worse nightmares. Mainly because it costs an arm and a leg to replace. You can avoid a huge cost by noticing signs of transmission problems and repairing them right away. Here are five transmission problems that you should not ignore and try to fix as soon as possible.

Slipping

Transmission slipping is when you feel like you are driving in a certain gear and then the car switches to a different gear on its own. This will happen randomly and unexpectedly, as well as the noise from your engine might begin to pitch differently. Another sign of transmission slipping is when your car feels like it is having a hard time. It also may feel like the car is not running at full power or potential and acceleration is not as it usually is.

Rough Shifts

If you are trying to shift gears and the transition from gear to gear is not smooth, then you may have an issue with your transition. Another obvious sign that something is up with our transmission is hear thuds. If you start to hear thuds after switching from gear to gear, then you should get your transmission checked out as soon as possible.

Delayed Response

This is when you switch from park to drive and your car takes a minute before acting as if it is in drive. Another way to tell if your car may need to get its transmission fixed is after you switch gears, there is a long pause, revving the engine, before the car engages in the drive gear.

Leaks

Since transmissions are sealed units within an engine, there should be no fluid leakage. If you notice any leaking, you should take your car to a specialist. You can test it yourself to see if the leak is constant or just a once and a while type leak. Once you notice the leak on the ground, place cardboard or any item to catch any future leaking to see if it is an active leak. If it is then you need to bring your car to a repair shop. If not, still bring it in but explain the issues and a mechanic can give you a proper assessment.

Check Engine Light

Normally when the check engine light turns on, it means the car is generating an error code. These should be checked as well but are not as severe as replacing a transmission, and doesn’t mean the transmission needs to be replaced. However, if you have the engine light on in addition to the symptoms mentioned above then you should make a repair shop appointment.

Signs Your Transmission is Going

It is not a good idea to drive with a failing transmission; not only is it dangerous, but the longer you wait, the more money you will spend to repair both the transmission and the damage it caused to your car! So we are here to tell you some of the red flags that indicate a failing transmission.

  • Overheating: Overheating can cause some major damage to your transmission; what causes overheating? Well of course the heat causes overheating. But the major cause of overheating is stop and go traffic and heavy towing; be sure to check the fluid levels, and if it’s leaking, be sure to change it!
  • Difficulty Shifting: If you’re having difficulty shifting, or the gears aren’t smooth, there is most likely a problem with your transmission. Make sure to have the transmission fluid checked, as well as the shift cables and clutch linkage.
  • Slip Issues: If the gears are acting up, or you’re having trouble accelerating or coasting, you might be experiencing a transmission slip problem. This is dangerous, and if you’re experiencing any of these problems, you should have us inspect your BMW immediately!
  • Clutch Issues: If you can’t shift gears because the clutch is still spinning with the engine, you have what is known as “Dragging Clutch”. If you hear a weird grinding noise when you’re changing gears, you may have an issue with the clutch, and should have it checked out immediately.
  • Clunking & Other Strange Noises: If you hear any type of clunking or whiny noise in your automatic or manual BMW, it usually indicates a major issue with your car.

So when determining the strength of your transmission, keep your eyes, nose and ears on any unique smells and sounds! If you have even the slightest inclination that your transmission might be failing, please bring your car into Boston Motor Werks as soon as possible!

BMW Transmission Service

We recommend getting a transmission service update for every inspection II, or for every 60,000 miles.

These services will include replacing the:

  • Fluid
  • Filter
  • Pan Gasket
  • For newer models we would replace the entire pan as the filter is built into the pan.

For manual or automatic transmission fluids we would use factory BMW fluids.

Our transmission service is affordable and will save you thousands of dollars in car ownership, and is one of the best investments you can make for your vehicle.

We recommend doing these transmission services, instead of doing what BMW dealerships recommend; they are all about the “sealed for life”transmission. BMW dealerships believe that you don’t need to do any work on your transmission, and it will last for 80-120,000 miles; however, after at the most, 120,000 miles, you will need a brand new transmission installed.

A brand new transmission, alone, costs anywhere between $4-5,000, and that is not including the service and hours it takes to install a new transmission.

So we recommend getting your transmission serviced at every inspection II or at 60,000 miles; it will save you so much money in the long run!
