Should be some transmission codes.
Check codes and reply.
If no codes, try transmission calibration, should make some codes after it fails calibration.
(transmission has to be hot to allow calibration)
Transmissions often fail in the scrapers. Check your filters and oil for debris.

There are two solenoids energized for every gear selected, forward or reverse. Numerical 1-4 and alphabetical A-D. Check for magnetism at the energized solenoids based on the gear selected. Check at each solenoid connector between the two female pins for voltage. This should narrow your problem down whether wiring, burned out solenoid, or internal transmission problems. I would strongly recommend performing an oil sample on the transmission.
