P0748 Governor Press Sol Ctrl/Trans Relay Circs
P1757 Gov Press above 3 PSI in gear with 0 MPH
Check the wiring first..... there is an 01 service manual in the faq section you can download. If the wiring is ok, replace the governor pressure sensor and solenoid. They are IN the transmission, easily found by dropping the pan. Change fluid and filter while you are in there, and maybe even adjust the bands.

Grab the 01 service manual, it will show locations and such in there. Pinouts may not be exactly accurate though... Keep that in mind. (manual is in the faq section, you can just download it.)
