TR6060 swap - clutch disengagement question

[rickpaw]

I recently swapped a TR6060 transmission from a 2012 Camaro SS. The transmission came with stock GM throw out bearing/Centerforce DYAD clutch. The hydraulic conversion kit is from McLeod, Pn 1434002.

The issue from day one was I couldn't get the clutch to release without the car sitting, and idle for awhile. The clutch also release normally when the weather was hot/warm. I was certain that there was no air in the system, or leak. The McLeod tech I talked to said I can extend the rod on the master cylinder to take up the slack, per se, but I'm not convinced that's the right way to do it.

Once every warms up, then it shifts/goes into gear just fine.



Now the master cylinder leaks so I'm going to replace it with another McLeod 3/4" m/c I have. Any suggestions I go while I have everything apart?

I agree with the McLead tech, just extend the rod to get a little more travel from the pedal. This will give you more travel at the MC, which will also give you more travel at the TOB, and allow for a clean release.

Thanks for the reply Andrew.

What I meant extending the rod was to lengthen it, so that it pushes against the pedal travel stop; and in turn "preload" the m/c. Hope that makes sense.

What I forgot to mention was, once I was able to get into gear, the clutch engagement is right off the floor. However, after driving/shifting it for awhile, the engagement moved up to about half way on the pedal stroke. I got a borescope and looked into the bell housing, and did not see any signs of leaks.

I'm going to put a rebuilt wilwood m/c back today, and tried to vacuum bleed from the reservoir. If that does not work, I may have to drop the trans and look at the TOB.
