my tremec tko is stuck in third gear. My friend is doing some paint work for me and was taking the car off the trailer. He bcked off in reverse no problem and pullued forward in first with no problem. he stopped the car, put it in neutral, shut off the motor and then put it in third. When he went to move the car into his shop he could not get it to shift out of 3rd. he has tried a little rocking of the car, driving up a bit in 3rd, giving the shifter a tap or two.
NOTHING
I may have to pull the shifter and most likely the whole trans.
Any suggestions on the possible problem and how to best fix it.
