my friend has a 5th gen (3.0) 5 speed manual and replaced his clutch with a stage 2, not sure on the brand all i know is it was red.


anyway, got the flywheel resurfaced, installed the clutch/flywheel and broke them in for 1k miles yet the clutch slips on high rpm gear changes


anything under 4500 it grabs and grabs hard, but 4500- redline it will slip like crazy


we have bleed the clutch time and time again and it still does it

any suggestions?

 

Could it be the syncronizers?

 

Hmm...

the huh? trans is brand new to.

 

Who installed all this?

 

The syncronizers have nothing at all to do with the clutch. Air in the line won't cause slipping either.

If it was all installed properly and cleaned it should be working fine. There could be some grease on the clutch from the shaft. There could also be an oil leak from the motor contaminating the clutch. Check the slave cilinder to make sure it's not leaking fluid into the bellhousing. Sometimes the added push needed to move a stronger clutch can be too much for an old slave cilinder and it can leak.

It's also possible he was sent the wrong part. Possibly a pressure plate designed for a smaller car but with the same bolt pattern. Finally, if the pressure plate bolts weren't torqued down properly (or in the right pattern) there could be some spipping. You're actually compressing the pressure plate when you torque the bolts and they can seem torqued down when they aren't. Especially if you don't follow the correct pattern and repeat it several times.

Does the pedal move smoothly? If the throwout bearing was installed upside down it could be binding and causing the clutch to engage more slowly which could cause slipping under hard shifting.

Unfortunately there's not much outside the bellhousing that can cause this kind of problem. If it's not a leaking slave cilinder he's probably going to have to pull the tranny and look at how the parts were installed.

 

going to have him check that out tommorrow and go from there.


Thanks
