Gday Chris and staff,
My car is a BA1 XR8 manual. Mods are : tune, advance headers, stock cats, berklee catback system, bluepower CAI , pumpgears/tensioners. The car has 90,000kms on it. I got it with 60,000kms on it and it was standard. So, After about 8,000kms the gears get heavy/notchy to engage and soon after this it starts to clunk on gear changes. This continues until it is impossible to engage reverse and very difficult to get forward gears. I get the clutch fluid bled and the car is like brand new, selects gears easy as, and shifts as smooth as can be. This lasts for about 7-8,000kms when I go through the whole routine again. I told the last guys that did the fluid change, that usually the fluid comes out black , so they put in valvoline racing fluid in an effort to stop it boiling black. This was about 1500kms ago but now I have the hard to select gears issue starting to happen again. They have no idea what to do. Im wondering if the exhaust system I have runs closer to the clutch system and is cooking the clutch fluid quicker than a standard system? Any ideas what could be my problem, Im in wollongong and no one here has any idea. Regards Shep |

I was talking to an ex F6 owner about his old car and he had to tell the new owner to get the clutch fluid changed at least at each service due to heat problems killing the fluid. As far as I know his car was stock, hard to believe hey?
Sounds you may have a similar issue, possibly due to your exhaust.

Yes this is something we have seen before...
Changing your slave to a metal one will make a differance ( by it off Mal Wood ) as the plastic ones are not the best. Even pick Mals brain when you are on the phone and he even might have some other ideas to help you..

yeh If you still have the plastic slave they will cause problems, the bore in the slave swells when hot and it wont keep it disengaged (slowly creap back) and cause clutch drag, with symptoms of notchy in every gear and hard to get gear full stop.
Also try GM the LS commodores that use the T56 have the same slave, shouldnt cost more than about $200. |
