Hey Tranny GURUS. Just wondering. I have a 4L60E tranny in my LT1. I finally figured out why it was not shifting after the new motor. (low ATF) Now for some reason the clutches 1-2 are really bad. IN fact the gear races the engine up on the transition from 1st to 2nd, I wanted to know I plan on going with a Manual Valve Body. With shift Kit. IF I Get those parts installed will that eliminate my Transmissions slips. And how fast will the shifts be with a FULL MANUal Valve body?? Thanks

I'm not a tranny "guru", but I think you may have hurt your 1st + 2nd gear? Running with low/no ATF is not good. If you pull it apart to install a shift kit and/or manual valve body, be prepared to replace 1st & 2nd clutch packs, or whatever the parts are?

 

I gotta bad leak coming from some were ITs leaking all over my Jet hots/ Prolly why its not shifting to its full potential cuase its loosing ATF. I gotta get that fixed. Will LOSS of ATF make the gears shift slow and even slip??

Loss of fluid will destroy the transmission, which in your case sounds like it did.
