While driving, it takes all gears but when I release the accelerator it kicks back to neutral and it does not have any fault codes. what could be the problem?

Hello,

There are several fuses I would check first, here is a wiring diagram that can help you see the fuses involved. Next I would scan the transmission or codes here are a couple of guide that should help you.

It could be pressure sensor or a shift solenoid there is no way to tell until you read the codes.

Please run some tests and get back to us so we can continue helping you.

Best, Ken
