People always wonder why I was able to run a bone stock trans way into the 10 launching at 7000 and shifting the same with over 400 passes and others' T56s fail much sooner with less power and less track use. The answer is simple I don't do stupid **** like shifting a synchronized trans without a clutch. I use it like it was designed to be used.

So call it harsh, but watch, that guy will be posting abot which rebuild kit he needs to buy within 6 months to a year.
Well I guess you must know what your talking about with that many passes and times like that........You know, if everyone could drive as good as you lots of people would be out of business LOL your not realy helping anyone are you and I'm not sure but I didn't think that the T56 was designed to be a Drag Racing trans

lol.

Not fallowing you how my driving ability will run people out of business. But I doubt my driving ability will be questioned by many on this site.

All sarcasm aside, drag racing is simply driving it more aggressively than some. The trans was design to be shifted with the clutch full depressed, with the shift speed not being part of the equation.

You can say the 10-bolt was not designed to take the shock 7000rpm clutch dump on a slick, which is why they brake.

You can say the factory clutch was not designed to hold more than a little over stock power output which is why they slip.

Sure, the T56 is not a drag race specific trans which is why a car with a Jerico or Lenco or even a TH350 may possibly run faster. But I do not use a T56 outside of its designed mechanical opperational specs. The trans was made to have the power disengaged during a shift, clutch in, shift, clutch out. And that is exactly what I do.

Honestly dude, Im telling you as someone who has driven quite a few T56-ed cars in my short lifetime, shifting this trans without the clutch. though possible, is not advisable. I was even told by Liberty, Six Speeds Inc and the guys at Tick that shifting a Faceplated trans under full power without using a clutch and not having a slipper clutch, would distroy the friction plate.

It may be cool, but the repair bill will not be.

I agree with your last post 100% What is a slipper clutch? I have an idea what it is for but how does one work?

Its basically a torque converter for a manual trans.

Its a clutch that uses counterweights to engage as rpm goes up. Like what the NHRA guys use. Depending on how you adjust it will depend on what RPM the clutch gives full clamp on. You come off the clutch and it will slip until that RPM at which point its 1:1 and you can ratchet through the gears w/o having to use the clutch. That's a quick and dirty explanation, I am sure someone else can give more detail.

ya ya now I know what your talking about. There was a time when people did use a real torque converter down the driveline from a manual trans, I guess that's when the slipper style clutch was built.

Yes you can, but only with a slipper clutch... I can do it with my clutch now, but it would cause severe damage to the friction plate.

The benefits are, its impossible to miss a shift, there is no temporary loss of power to the rear wheels during a shift like you are would have using synchros.

What kind of shifter did you use before the faceplate?

Watching some of your non faceplated vids, you shift hella fast. Is that powershifting or just tougher synchros and 5.0 with a lot of practice?

I don't let off the throttle, so yes, it is powershifting. The trans in the raceing vids is stock, so unless GM through gave me some super duper synchros, they are no tougher than any other.

You are right... I have no clue what I'm doing. Please enlighten me.
