I just recently had a new T56 put in my 99 SS Its backed by a centerforce dual friction clutch and all new hydraulics. The transmission drives and shifts great if you are driving nice but as soon as you mash on the throttle and go to bang a gear it won't come out of gear easily or go into the next easily. Does anyone know my problem?

 

Try doing the Drill Mod..

 

I have no clue how to do that.

 

You drill out the restriction on the Hydraulic Line coming from the Master..there is a few write-ups on it.

 

do a search for the drill mod

or you can buy a tick master cylinder

 

drill mod is fail. doesnt work. do a tick if you want a for sure cure.... unless its your slave.

 

just put another new slave in it a few hours ago and bled the system really good. Still having the same problem.

 

I'm running all stock Hydraulics, did the Drill Mod and I assure you that I row the Gears pretty damn easily.

Then again having the Speed Bleeder does help ensure it's completely bled.

 

Ok I'm goin to do the drill mod today will post results.

 

The hydraulic systems on these cars really suck unless you have them spot on. When you hit the throttle hard, you increase the centrifical force applied to the clutch assembly which makes it a little harder for the hydrualics to keep up unless they are right on the money.

 

I am new to ls1tech and I just want to let you guys know ya'll are awesome for givin me all this advice

 

new slave and master cylinder still having the same problem. could it be something to do with the clutch or flywheel?

 

What shape is the pressure plate in? I've seen issues like this when the pressure plate is not strong enough to provide the clamping force needed. Normally you will feel the clutch pedal drop some or feel a pulsing in the pedal.

 

It's a brand new centerforce dual friction clutch kit so everything should b good. Sometimes if I get on it up to about 6k rpm range and the clutch it to shift the clutch takes a few seconds to disengage.
