Reply to "clutch slips when I get on the gas."

I just want to add that you did not say which clutch you have installed.

The Centerforce dual friction for instance WILL go through a period where it will slip briefly.
It is more like a chirp rather than driving down the road and seeing your rpm's rising while the car isn't going any faster though.
There is a difference.

What happens is that the flywheel side of the clutch disc has to take the factory glazing off of the lining.

It doesn't show as such when you look at the new disc but it is there and that is the hard side of the dual durameter lining.

At times it feels like the new automatic transmissions trying to go into full lockup.

Some cars take longer to get over this than others.

That, the Centerforce, is also a diaphram fingered pressure plate. You do not want the throwout bearing riding on the fingers as the initial adjustment.

The clutch will heat up as the engine does and will put release pressure on the fingers if you adjust it that way, causing it to partially release while you are driving.

A long clutch (three finger) needs a MINIMUM of something like .035 clearance at full release and a diaphram (centerforce) .045".

You measure this with a feeler gauge at full release between the disc/flywheel/pressure plate.

The original type three fingered clutch adjusts differently and has a different feel to it. The in/out feel through the pedal is different and some mechanics do not understand the difference.

The diaphram is smoother and less herky/jerky but slips more doring break in.
