A guy I know who builds a lot of show rods was telling me last night that you have to idle the motor and keep changing gears to get the trans to "pump up". He says you do this to fill the valve bodies, and this must be done or the trans won't work. Any truth to this? I have never heard this before. My external fluid filter is full of fluid from the initial startup, I topped off the trans and still nada...wont move, it's like every gear is neutral. Brad..
Brad, I didn't do it that way when I rebuilt my 700R4. But different strokes... Check every gear in manual position with minimum TV pressure and max TV pressure. For minimum TV pressure just read the gauge with the trans in the selected gear. To get max TV pressure pull the TV cable at the carb or throttle body all the way out and read the pressure. I have an ASTG manual all the mins and max pressures if you need me fwd them to you.
