Only drives in reverse?

There is a transmission control relay and a fuse # 37 in the power distribution center on the right side of the trunk I would check first. Swap out the relay and check the fuse.

On the right side of the transmission there is an electrohydraulic control unit that goes out in these cars. Here is how to change it out which should fix the problem unless you have an internal mechanical failure. Here are the wiring diagrams as well so you can see how the system works and the fuse and transmission control relay as well. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

Can you please tell me what the code numbers are? Here are the instructions for the 42Rle transmission. I see for the 42Rle unit the TIPM is included in the operation. I have seen the TIPM go bad as well, i think we should do a CAN scan. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Also, please check the fuse #2 and #6 in the TIPM. Here are the wiring diagrams and instructions for the valve body replacement with the pressure regulating solenoid for the 42Rle. Check out the images (below). Please let us know what happens.
