The AT will not go into gear unless I reset the PCM (either by battery disconnect/fuse removal-reinsert-or OBD scanner tool).
Once I reset the PCM is will go into gear, drive for a bit and then it needs to be reset again. when I say a bit it could be 500 feet or 1/4 mile. Any recommendations? There are no error codes.

Does it upshift when you drive it for a bit?

Yes, once it is reset it will shift through all gears. However, as it heats up the time of failure shortens. If it is cold/cool, all conditions seem normal.

Update: No codes register when it fails. Unplugged speed sensor, got P720 error, so I guess PCM works.
Tested car on jackstands. Right wheel turns but left does not.
Tried to get it moving but is would not continue to turn (1 spin = 1 turn, no momentum)

Tested solenoids Ohms/operation satisfactory
-Shift solenoid A&B OK
-linear solenoid OK
- Lock up Solenoid A&B OK
