Car Still Jerks After Rebuilt Transmission

Possible Causes

There are a number of possible causes for a car to still jerk after a rebuilt transmission has been installed. Some of the most common causes include:

Incorrect fluid level: The transmission fluid level must be correct in order for the transmission to operate properly. If the fluid level is too low, the transmission may not be able to engage the gears properly, which can cause jerking.
Dirty fluid: The transmission fluid should be clean and free of debris. If the fluid is dirty, it can clog the transmission’s filters and valves, which can also cause jerking.
Damaged gears: The gears in the transmission can be damaged during the rebuild process. If the gears are damaged, they may not be able to engage properly, which can cause jerking.
Incorrectly adjusted shift linkage: The shift linkage must be adjusted correctly in order for the transmission to shift smoothly. If the shift linkage is not adjusted correctly, it can cause the transmission to jerk when it shifts.
Electrical problems: Electrical problems can also cause the transmission to jerk. For example, if the transmission control module (TCM) is not functioning properly, it can send incorrect signals to the transmission, which can cause jerking.

Troubleshooting

If your car is still jerking after a rebuilt transmission has been installed, you should take it to a qualified mechanic for troubleshooting. The mechanic will be able to diagnose the problem and recommend the necessary repairs.

Here are some tips for troubleshooting the problem yourself:

Check the transmission fluid level and condition. The fluid level should be between the “full” and “add” marks on the dipstick. The fluid should be clean and free of debris.
Check the shift linkage for proper adjustment. The shift linkage should be adjusted so that the transmission shifts smoothly into all gears.
Check for electrical problems. Look for any loose or damaged wires or connectors. You can also use a multimeter to test the voltage at the TCM.

Conclusion

If you are experiencing jerking after a rebuilt transmission has been installed, it is important to take the car to a qualified mechanic for troubleshooting. The mechanic will be able to diagnose the problem and recommend the necessary repairs.

By following the troubleshooting tips above, you may be able to fix the problem yourself.
