What Causes Transmission Slipping After Fluid Change?

If you notice that your vehicle begins to shift gears without your permission, accompanied by a noise or pitch change or When the car has trouble changing gears, the question of what causes transmission slipping after fluid change arises.

A vehicle’s transmission is essential for it to move and operate properly. A transmission’s job is to transfer power from the engine to the wheels of the driving mechanism.

What Causes Transmission Slipping After Oil Change?


When you use old fluid, it can discolor and cause varnish deposits to form inside the system. These deposits typically float around the old fluid and do not accumulate anywhere as long as the fluid is used which causes transmission problems after fluid change.

  1. When you replace the old fluid with new fluid, the deposits are washed away and turn into sludge, which sticks to the filters in your transmission system. This prevents transmission fluid from flowing through it.
  2. If you serviced the transmission but did not replace the filter, it became clogged, depriving the system of hydraulic pressure. This could result in slipping. Transmission filters are frequently poorly retained and will occasionally fall off and rest on the bottom of the pan when replaced. This can result in slipping.
  3. 90% of the time, slipping in manual transmissions is caused by the clutch. Depending on your driving habits, a clutch disc can last anywhere from 20,000 to 200,000 miles.
  4. A faulty seal, ruptured fluid lines, a leak in the pan, or a crack in the torque converter can all be causes of a transmission pan gasket failure.
    Examine the fluid level and the underside of your vehicle around the pan and on the drive for any signs of a leak.
  5. It is best not to use cheap transmission fluid because it will leave most deposits behind. When these deposits accumulate on your filter and prevent transmission fluid from flowing, the transmission’s components heat up and create more friction.

How To Stop Transmission Slipping After Fluid Change?


Transmission Slippage can be fixed with help of various mediums but it depends on the type of problem here are some of the fixes you can try to fix transmission problems after oil change.

1. Refilling Low Transmission Oil

1. Park the vehicle on a level surface, engage the parking brake, and turn on the engine. Leave the vehicle in neutral or park. Allow the engine to warm up and continue to run throughout the operation.
2. Locate the automatic transmission fluid dipstick, which is usually near the point where the transmission meets the rear of the engine. It has the appearance of an oil dipstick.
3. Examine the markings on the end of the dipstick. Your dipstick may have two “full” markings—one warm and one cold. If the transmission fluid level does not reach the “warm” line, add automatic transmission fluid.

2. When To Change Transmission Fluid?


With a clean rag or paper towel, wipe down the dipstick. Then examine the transmission fluid’s color.

• If the fluid is bright pink, it is new. There is no need to change it.
• If it’s light brown with a hint of pink, it’s time to replace it.
• It will be very dark brown if it hasn’t been changed in a long time. It may also have metal particles floating around. This represents transmission damage.

3. Flushing Out Transmission Oil


This method allows you to change the entire fluid. Connect a transmission hose to the line that runs through the transmission. Connect it to the output.

By pumping new transmission fluid into the transmission, the old fluid is pushed out. We caution that this method should only be used if the current transmission fluid is in good condition and shows no signs of damage.

4. Replacing Transmission Filter

1. Raise the vehicle and remove the pan. As you do this, a catch pan and a tarp should be placed underneath it.
2. Discard and replace the filter
3. Remove and replace the old transmission pan gasket.
4. Attach the pan and fill it with Fluid.
5. Begin the vehicle and inspect for leaks.

5. Checking And Fixing Leaks

If your transmission is leaking fluid, you must locate the source of the leak. Experienced do-it-yourselfers can usually research the vehicle-specific symptoms, replace the faulty parts, and resolve the issue.

If you are unsure about repairing the problem yourself, we recommend watching this video.

6. Worn Out Clutch

It’s difficult to shift gears. The clutch pedal is stuck, vibrating, or appears spongey or loose. Poor acceleration, but the ability to rev your engine. Temporary loss of acceleration caused by a slipping clutch. Here’s a video showing how to fix clutch problems.

Should I Drive My Car In This Condition?


Driving with a slipping tranny is strongly discouraged. If the lubricant is depleted or burned, it can increase friction and heat between the moving parts, resulting in severe wear and tear and we don’t know what primarily caused transmission problems after fluid change.

You might even find your car overheating and not moving. Not to mention that driving with such a problem is extremely risky. All of these issues will cause inconvenience in the operation of your vehicle and may also pose other risks such as losing speed control or being involved in an accident.


Transmission slipping after fluid change is a common issue. However, we hope that after reading this article, you will have some useful information to figure out what to do if you come across it.

Always keep an eye on your vehicle’s fluid level, and if you encounter any strange problems, contact your mechanic right away.
