I've already replaced the transmission control solenoid. I've replaced the transmission control relays multiple times. This code keeps coming on and the car goes in to limp mode anywhere from a couple hrs to a day later. I'm at my wits end with this car. This only started happening after I had to replace the main fuse box. Any ideas?
1st code was for the relay and the generic p0700 code. Replaced the relay and it was fine for a month or so.
2nd code was for relay, output sensor and p0700. I replaced the relay and the output sensor. It was ok for a day.
3rd code was for relay, transmission control solenoid (p0888) and the p0700. I replaced the relay and solenoid and it was ok for about 2 hrs and now it has the same codes. P0700, P0888.
