You obviously have more experience with mopar transmissions than I do. Problem; I rebuilt my transmission, along the same lines as many on the web A 727 that sits behind a 400 big block in a 71 plymouth duster. I have NO passing or kickdown gear. I can hand shift and 1st through 3rd are there with no slippage. I adjusted the throttle with the kickdown lever so when carb is wide open trans lever is fully depressed back. NO passing gear or kickdown. Also trans shifts through gears really fast, shifts from first to third by 35 mph. I have pulled the tail shaft and checked and cleaned the govenor, also dropped the transmission pan and pulled the valve body taking it completely apart noting where the ball bearings go. Still the same... One question, this valve body is out of a RV transmission, would that matter? HELP!!!
