Hi fellow 4x4 buddies. So the other day i am driving down the freeway in my OJ and suddenly my revs go up. i lay off the gas and apply small amount of pedal and nothing. I am in gear and I have no engine/trans lights on. I turn the O/D off and still nothing. I coast off an exit and then I have the transmission back again. I have good red fluid and no foul smelling oder either. There are over 210k original miles on this rig that is my daily driver. It has been dependable all for the front end needing a complete overhaul. I just dont know where to start. I am a DY kinda of guy. Any pointer or things to look for or start with would be very helpful. Transmissions are not my forte really so I dont want to make any more problems than the one i have.
