Hello, Just dropped the pan and changed the fluid,filter, and changed the governer pressure solenoid. Used Mopar ATF4 fluid. Nothing changed and there are no fault codes. Jusr don't think it is the torque converter or the tranny needs to be rebuilt because it all of the sudden happened.
When I started up my 1999 1500 and tried to drive away all of the sudden the transmission wouldn't work in any gears forward or reverse and I had to rev it to 3,000 rpm's for it to move at all. Never had any issues until that time and the truck has 80,000 miles on it. Any ideas?
