i have the 3kgsks and the stock plate....and when i rip the truck it will rev really nicely to 2300rpms then pauses...rpms dont go up and then surges forward with the rpms lal the way to 3200 if i let it.....this happens in the gears when unlocked......

what in the world is that?....is that the stock plate? or am i actually experiencing some sort of TC stall at that rpm?

 

It sounds like trans. but not sure , wanted to post to watch for anserws, I first noticed it with mine and thought it was defueling , get on it to pass at 40-50 , then a couple times from a stop-some one trying to cut me off. One of the times at a stop I noticed the tach and saw it climb to 2800-3000 then I knew that it must be trans. from what I've read about up grading trans. it sounds like clutches slipping ,T.Q. and fliud leaking[seals not holding the pressure] so this seems to give more reason for the expence of trans. up grade- the problum is this one is doing what I ask it unless I try to drive like a hot rod[ whitch its not yet...]

 

My .02 is that your stock plate is causing this.......IMO, a GSK and a stock plate is not the greatest combo. Grind that stocker to a #100 and watch the GSK shine. The #100 will allow a much smoother transition through the throttle range without multiple defuel points like the ugly stocker.

 

i thought so CTDnut....the stock plate is a "stepped" profile...so it makes sense that that would be it....

 

does it feel like the pedal is being pushed back against your foot? Mine would do that with my stock plate in.

 

You can see, feel & HEAR it on the plates with a big nose.
That's why #10, #4, #0, #100, etc. all compliment the governor springs.
Now the question is how long will that stock transmission last if you're driving it that hard. hhmm?

Your truck may not be a hot rod, but does have enough horsepower to over power a stock torque converter. Dave (Goerend) uses the expression driving through the converter. Burns up the lock-up clutch real quick due to the high rpm mismatch between impellor & turbine.

Been there done that, got a Goerend rebuild.
