In this brief guide, we are going to provide you with the common Chevy transmission problems and what you can do to rectify these problems before they worsen.
Chevy transmissions manufactured by General Motors are designed for RWD and AWD/4WD applications.
This type of transmission had features such as clutch-to-clutch operation with a wide gear ratio for optimum performance and efficiency. We’ll mention a few common problems with these transmissions.
What are the common problems with Chevy transmission?
Most of the common problems with Chevy transmission are:
- Slipping or no reverse
- Shifting malfunction
- 3rd or 4th gear hard shift
- Transmission grinding noise
- Shaking and shuddering
Why is slipping or no reverse a problem with Chevy transmissions?
If you are not getting the required amount of torque and acceleration from the drive or if you’re not able to engage in reverse then for sure you are having a problem with your Chevy transmission.
What signs are shown by this Chevy transmission problem?
You would usually feel or sense a loss of acceleration when you press the throttle pedal and this can be taken as a sign of this problem. Also, you would get specific error code from the diagnostic tool if you plug it with the Chevy transmission control unit.
How to fix this Chevy transmission problem?
You need to first check the condition of the solenoids or the fluid in the system. Usually the solenoids wear out and need to be replaced to solve this problem.
Why is shifting malfunction a problem with Chevy transmissions?
Chevy transmission gear systems are not designed to slip and if you are experiencing slippage then it is definitely a sign of a problem with the mechanical components of the transmission.
What signs are shown by this Chevy transmission problem?
Usually you would get an error in the range to P0780s or further if you are experiencing this sign of a Chevy transmission malfunction. Also if the shift solenoid is broken or malfunctioning then you would get an error code P0745 or above.
How to fix this Chevy transmission problem?
Replacing the solenoids would work and you would not get the sign but if there is a problem with the mechanical component then it is better if you would visit a mechanic or service station.
Why is 3rd or 4th gear hard shift a problem with Chevy transmissions?
You would want a seamless and smooth shift even at low throttle input, so if your Chevy transmission is shifting harshly or slow even at high throttle then there is definitely a problem.
What signs are shown by this Chevy transmission problem?
You would immediately notice and sense if the Chevy transmission is shifting harshly from one gear to another as this is one of most important issues with Chevy.
How to fix this Chevy 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 grinding noise a problem with Chevy transmissions?
These Chevy transmissions are not manufactured to make such unpleasant noises and if you are hearing such grinding noise while driving then you immediately check with your mechanic as this might be a serious issue.
What signs are shown by this Chevy transmission problem?
You will hear these noises while driving and will be very unpleasant to your ears which can be taken as a sign that the transmission is having some problem.
How to fix this Chevy transmission problem?
Normally this sound means that the sunshell within the differential assembly needs to be replaced as it might be fractured. The entire differential assembly must be removed and rebuilt to fix this problem.
Why is shaking and shuddering a problem with Chevy transmissions?
Because shaking and shuddering would mean the Chevy transmission is not functioning smoothly as automatic transmissions are designed for a smoother drive than manual. Therefore if you’re experiencing shuddering when you accelerate then it means you have a problem.
What signs are shown by this Chevy transmission problem?
Shuddering itself can be taken as a sign of this Chevy transmission problem because automatic transmissions are not meant to shudder when loaded or accelerated.
How to fix this transmission problem?
Visiting your trusted mechanic or service center at the earliest is possibly the only way to fix this issue as the weights that control the pulleys might be worn out and it requires experience and expertise to repair this problem.
How to diagnose these common problems with Chevy transmission precisely?
If you need to precisely diagnose these common problems then you need to use a diagnostic tool which is software based and can be connected to the vehicle electronic system as Chevy has fully electronically controlled heavy duty transmission.
How to prevent getting these problems in the first place?
To prevent these problems you need to change the Chevy transmission oil as per the manual or when it is too dirty. This is the easiest and most effective way to take care of your vehicle transmission and also drive your vehicle in a recommended way.
FAQs: Chevy transmission problems
Why are Chevy transmissions bad?
Issues with the torque converter and the transmission, or both are what causes the jerking and shaking inside the problem creates excessive friction across gears, hydraulic systems, and surfaces.
Inside the problem creates excessive friction across gears, hydraulic systems, and surfaces. The lawsuit maintains that the “Chevy Shake” defect can cause the premature failure of the transmission.
Has GM fixed the transmission problems?
Yes,many owners have found that the new fluid does indeed fix the shudder issue. Since the service bulletins have come out, after driving for a week or so, the new fluid cleans up many of the internal issues as the adaptive shift algorithms go through their relearning process.
