here is my problem so far, 1-2 shift is about right. engine rpm flares a bit between 2-3 and i think 4th is ok, been scared to drive it far enough to really find out. and suggestions from any pros? thanks -art

 

anyone?

 

i guess ill just start throwing parts at it? corvette servo is on the way.

 

Pressures are a little on the low side, in my experience 2-3 flare is usually from worn 3-4 clutches.

 

This thing has less than a mile.I hope no clutches are burnt

 

Well in that case, could be cut or damaged lip seals on the piston, maybe a bad sealing ring on the input shaft. Could also be some garbage in the valve body, the valves are very sensitive to dirt and can get stuck.

Did you build the transmission or a shop?


Dana (Pro Built Automatics) is the true expert on this board. Hopefully he'll chime in here, if not maybe try to PM him.

 

the trans was built and dynoed at the local college.but this was 3 years ago. never been installed till now.

 

i ordered and installed a corvette servo. installed in about 30 mins. now the problem is gone? now it shifts really well.
