Odd usually no reverse so the rig just acts like it is in neutral, this one I would take it to a tranny shop, it sounds like a tear down to me but it could be a TCM or solenoid problem, electronic transmissions can do some strange things when signals get mixed up.
What was wrong with your transmission am having the same problem with my truck
The front band was loose and let the fork fall out
Thank you I guess it's to the shop it goes
