won't shift into 3rd gearat full thottle

or heavy part throttle unless I let off the gas completely. The 4l60 has a shift kit and and a 3200 stall. I have removed all tq and adjusted part throttle shifts. Everything else seems to working fine. Any Ideas? Thanks

Either that or your 3/4 clutch pack is toast :(

looking thru it, i didnt see any shifting problems, Maybe you should command a sooner rpm shift instead of the 6000 rpm one..

He is right about the 3/4 clutch maybe on its way out.


Or, your throttle posistion sensor is not adjusted correctly, or is out of range.

thanks for looking. We just put this car together it only has 52000 on the tranny. It was all stock before the 402 and converter , shift kit. It shifts fine at part throttle and seems to hold the power in drive ok.
