My car has really spongey shifts, and when the rpms go up as you about to shift it feels like the clutch slips, but the rpms don't shoot up. If im goin down the interstate and start pushing the gas a little harder it dose that slip feeling. The clutch is fairly new, could it be a torque arm bushing or my Jpos two piece driveshaft wearing out.:hmm:

When you installed the clutch.... did you torque to specs and make sure that it seated correctly?? If its getting a slip feeling, I would also check to make sure that nothing is leaking on the clutch disc itself...

Was the slave and master cylinder replaced with the clutch? Was the flywheel resurfased or replaced?

...and if so, did you bleed the system?

Well I did torque it, but I didn't resurface the flywheel. If something was leaking on it wouldn't it start to make a spot on the ground. I have no signs of leaking fluids. And I didn't replace the slave and master cylinder, the lady I bought the car from said she had a clutch put in, then it blew a head gasket, but I don't think they would have replaced the master cylinder.

Hahaha yeah, I'm gonna git under it and look to see if I can spot anything, my dad thinks it could be the driveshaft goin bad.

It only dose it in acceleration and up hills.

It would have nothing to do with the drive-shaft. The sponginess comes from lack of pressure against the clutch/flywheel. If i had my guess, it would be the slave inside the tranny causing it (especially if its never been replaced). You wouldn't usually see any signs of leaking from this. If the master is going bad it will usually leak into the car, so look around the clutch pedal area for the the fluid. It could easily be the flywheel as well if it wasnt resurfaced, it could be glazed over from past abuse.

Any noises when you press the clutch in? TO bearing on the way out perhaps?

Naw no noise, it dose it most when its not at running temp.

Cold temps=thicker fluid which means slower shifts. Something is definitely wrong with your hydraulics.

How bout its a Damn weak injector, that's why its been doin it. Its not putting the fuel to it, and it temperature sensitive. Its been alot warmer today than it has been and it ran great. And thats why it dose better at running temp. And you can smell a difference in the exhaust.

So it feels more like a misfire then a slip?

More like a loss of power. You can kinda hear it when idling
