Bummer. I was hoping it would have coded to indicate a shift solenoid issue. Since it didn't, that can only mean there is either a fluid level/quality issue with a plugged filter or there is a internal mechanical issue with the transmission clutches/discs inside the transmission.

The only other cause that can do this is if there is a engine torque issue which is usually caused by a bad fuel filter on these engines, but what throws that off is you don;t have reverse gear, which puts the issue right back on the transmission itself.

Sounds like this needs a clutch disc replacement from what is described.
