AT and Check Engine lights are still on after TCM rebuilt. Transmission still jerking.

The speedometer sensor is also prone to failing. If you've already inspected/serviced the transmission fluid and filter and already had your TCM rebuilt, scan the vehicle with an OBDII scan tool.

 

If you have the "P0715 - Input/Turbine Speed Sensor "A" Circuit DTC," chances are it's a faulty speedometer sensor. Have it replaced and then performing all the necessary tests should resolve this issue.

 

When a speedometer sensor fails, it can result in gears hesitating or jerking when shifting.
