I have a 67 New Yorker that I added the Transgo 2 reprogramming kit to. The car drove for 2-3 miles then it stopped. It acts like it's in neutral regardless of which gear it's in. The shifter moves the gear selector at the transmission but the car won't move. I've checked trans fluid and it's full with the car running. Can anyone offer any advice??

 

is your trans full of fluid? maybe you broke an axle?

 

Thanks. took the pan down and the shift arm came out of the notch that moves the shift control spool valve. bent the arm down and that problem is handled.
Take care.
