clutch or tranny problem ???

at wot, my car will just rev out w/ basically no accelaration. this problem just started happening.

If it's reving the motor and not accelerating it's most likely your clutch.

It is the clutch, my car has done that for a few weeks now, the clutch can't hold the boost and it is slipping under high torque.

Yup get yourself a clutch buddie.

k thanks i was hoping it was a clutch instead of my tranny.
rite now i have a stage 3 shep tranny w/ a act 2900 with street disc both have about 4500 miles I've launched the car twice and use it as a daily driver. any suggestions on what clutch i should go with ??? 385 whp 360 torque thanks again

4500 miles on the clutch with only being launched twice, it shouldn't be bad yet. Are you sure your clutch is adjusted right? Maybe the throw out bearing is preloading the pressure plate.

Agreed. It seems unusual that your clutch with a 2900 PP and less than 5K miles on it, driven the way you describe should be failing.

1) Check clutch adjustment as suggested

2) Did you have the flywheel machined for the correct step height?

3) Oil leak from rear main seal?

 

[jonk00000]

i think its possibly the rear main seal. if that is my problem, will i need a new pressure plate as well as a disc??
ive heard from some people that i can clean the pressure plate off
