I just rebuilt a 904 transmission. Stock rebuild. Before putting the valve body back in and buttoning it up, did an air pressure test, (about 30 lbs). I hear the clutch packs engage and the rear servo engages strong.
Problem is the front servo. It's blowing air out. I took the spring and top cap (whatever it's called) out and applied air. It blows the piston out of the bore. When there's fluid in there will it make a difference and piston get more pressure behind it?
