I've had the Exedy Twin HD for 4000 miles, with 4 dragrstrip launches and two street launches. At first, driveability was flawless, but now, I'm starting to experience something strange.

Sometimes during normal stop/go driving (not racing), when I press in the clutch in to upshift, I can't get out of the gear that I'm in, i.e., I'm locked in. This usually happens right after I decelerate while in gear.

When this happens, it feels like there is still a load on the engine, even though the clutch is pressed in...I think the clutch may be sticking to the flywheel. I can force it out, but this feels almost like shifting with the clutch engaged. If I wait for a few seconds, or blip the throttle (while clutch pressed in), it comes right out of gear and the rpms drop.

I've learned to avoid the problem by giving the engine a slight rev during every shift (push in clutch, rev, then shift).

The strange thing is that shifting at high-rpms or shifting aggressively is no problem -very smooth. I only have this "sticking problem" when shifing at low rpms while coasting in traffic.

I tried two things so far:

(1) adjusting the clutch pedal to grab at a higher position,

(2) bleeding slave cylinder

neither one helped.

Any ideas?

 

any ideas?

 

Disc/discs may have been warped upon install, and the splines on the input shaft may not have been properly lubed. Generally you are not going to get it fixed without pulling it...

 

Thanks Zeus,

Someone mentioned in another post that upgrading the cylinder rod will help, but it hasn't been elaborated on. Ever hear about this?
