When i put my 87 cutlass supreme into drive or neutral, it works fine, it goes right into gear, and even when i put it in reverse. but when i put it in reverse, the car wont move, it acts like its in neutral. is this an internal transmission problem? or could it be a transmission filter? or something else? something less expensive lol.
This is an internal problem on your 440T4. Looks like its got to come out.
