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.

Wow, thank you, I'll check.

Sorry I don't have the nag transmission it's a 42Rle I looked under dash no modular for transmission and the plug is square for the transmission. Connecter would it be same guide for hydraulic pump? thank you

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.

Codes are p0760 and p0073. I changed solenoid pack all of them are good now scanner says solenoid c again. I just bought a decent scanner I will try can scan. let me know if you need anything else. thank you

Fuses 2 is good fuse 6 says 25amp there was a 30 also etc temp is 225 f is that high.

That temp is a little high, was it a warm day?

P0760: This code indicates a problem with the "Shift Solenoid C".

P0073: This code is associated with the "Ambient Air Temperature Sensor Circuit High input".

I would check the main wiring connector to the transmission to check for rust or corrosion on the connector pins. Upload images if you have question about what you see.
