What are the problems with GM transmissions that still have not been fixed?

In this brief guide, we are going to tell you if GM has fixed the transmission problems and if not what you can do to rectify these problems before they worsen.

GM mostly has automatic transmissions in their vehicles and does not require any manual input to shift gears while driving as most of the cars have automatic transmission. Various sensors and mechatronic systems work in coordination to shift gears automatically. 

Although GM automatic transmissions have a global reputation for quality, reliability and durability. However, there are many problem with automatic transmissions which have not been fixed and we’ll tell how you can solve them

What are the problems with GM transmissions that still have not been fixed?

Some of the most common problems with GM transmission are:

  • Shaking and shuddering
  • Torque converter malfunction
  • Harsh shifting 
  • Transmission overheating
  • Lack of response

Why is Shaking and shuddering a problem with GM transmissions?

Because shaking and shuddering would mean the GM transmission is not functioning smoothly as automatic transmissions are designed for and also they are meant to be a smoother drive than manual. This could cause a very unpleasant driving and passenger experiences

What are the signs of this problem with the GM transmission?

Shuddering itself can be taken as a sign of this GM automatic transmission problem because automatic transmissions are not meant to shudder when loaded or accelerated.

How to solve this GM transmission problem?

Visiting your trusted mechanic or service center at the earliest is possibly the only way to fix this issue as the internal mechanical components or dampers might be worn out and it requires experience and expertise to repair this problem.

Why is Torque converter malfunction a problem with GM transmissions?

If your torque converter or if you are not getting the desired response when you release the brake and press the throttle pedal then you are most definitely experiencing torque converter engagement or disengagement problems.

What are the signs of this problem with the GM transmission?

Firstly you would be unable to stop the car when releasing the throttle pedal for disengagement problem and secondly for engagement from even if you press too much throttle the car will not move forward.

How to solve this GM  transmission problem?

If the clutch of the torque converter is worn out then you need to replace it or else the solenoid might be broken which also might need replacing. In the worst case the entire assembly needs to be replaced if the state of the torque converter is beyond repair.

Why is Harsh shifting a problem with GM transmissions?

You would want a seamless and easy shift even at low throttle input, so if your GM transmission is shifting harshly or with difficulty even at low speed then there is definitely a problem.

What are the signs of this problem with the GM transmission?

You would immediately notice and sense if the GM transmission is shifting with difficulty from one gear to another as this is one of most important issues with GM.

How to solve this GM  transmission problem?

Firstly try replacing the transmission pressure sensor, if that doesn’t work then check for an oil leak in the servo assembly of the particular gear. These are primarily two fixes for this problem.

Why is Transmission overheating a problem with GM transmissions?

Overheating would mean the transmission is operating at a temperature above its normal working temperature. This can cause damage to internal components and could result in complete stalling of the vehicle. This is why overheating is a problem of the GM transmission.

What are the signs of this problem with the GM transmission?

Generally when a GM transmission overheats an error is shown. This error is not immediately visible on the screen but requires a diagnostic tool to get these actual error codes.

How to solve this GM transmission problem?

After cooling down the transmission check the gearbox oil for its condition. Change it if it is too thick and completely black. Also, check your clutch if it is the problem behind this malfunction.

Why is Lack of response a problem with GM transmissions?

While in the vehicle on road if you experience lack of response while pressing the throttle then this could result in an unpleasant drive for you. So, this is a problem with your GM transmission.

What are the signs of this problem with the GM transmission?

Usually you would instantly notice this sign of the problem as you get a hesitation sensation or slow response from the car when you try to shift.

How to solve this GM transmission problem?

Resetting the software settings or checking the gear ratio sensors could be a solution. Also, visiting the nearest service center or your trusted mechanic would be the only way to solve this problem because this might be a serious transmission problem you are facing.

How to precisely diagnose these common problems in GM transmission?

To properly diagnose these problems, you need a scan tool to read these codes from the Transmission Control Unit. Firstly, If a GM transmission is malfunctioning, it immediately informs the driver with an error message on the screen.

How to prevent getting these problems in the first place?

Regularly changing your gearbox oil and other lubricants may save you a lot of trouble and money in the future. Although many experts suggest different number miles for servicing, your car manual will give you a proper recommendation when you should change it.

FAQs: Has GM fixed the transmission problems

Will GM fix my transmission?

Maybe, as for some 2021 models, at least, GM has announced a Customer Satisfaction Program for some vehicles that involves replacing the transmission. However, these two issues don’t look related. So, GM is going to replace those transmissions with a new one at no cost to the owner.

Is the GM 10-speed transmission better than the 8 speed?

Finally, the 10-speed transmission is designed to replace 6-speed and 8-speed transmissions. GM and Ford built the transmission to minimize spin losses. Reducing spin loss guarantees that the 10-speed transmission’s gears work more efficiently than its 6-speed and 8-speed counterparts. 

Conclusion

In this brief guide, we have told you if GM has fixed the transmission problems and if not what you can do to rectify these problems before they worsen.
