My speedometer and tripmeter went out and at the same time my transmission wont shift out of first gear. The error code that comes up from holding trip switch is 400.1. The codes I got from advance auto are P0700, P0442, P0720, P0731, P0500. I changed the output speed sensor and disconnected the battery and neither worked. Any more ideas?

The 442 code is a leak at evaporator and it is either the solenoid or it needs to be smoke tested to see where it is. Sometimes it is a bad gas cap as well and when tightened anytime three clicks must be heard. The other codes are speed sensor related as the pcm is not getting any which means it can be a wiring issue or connection as you have replaced the sensor.
