Well, when the shifter is put into 'D' and I step on the gas, the Jeep barely moves, but it revs up.
I can manually shift the gears from 1-2, to 3, to D.
I unplugged the TCM and I could still shift gears manually; which leads me to believe that the solenoids are still fine and that it's an electrical problem.
I was going to slap a multimeter on the TCM and test the wiring according to the "shift pointers". I just havent had the time to scab a multimeter and test all the wiring to see if the TCM is toast.
I got some guidance that it's possible that if the TCM is functioning property, that the TPS could be to blame.
