Clutch slave

[twobjshelbys]

My clutch slave cylinder is leaking. I had no clutch, filled and bled, and all the fluid is on the floor. A shop replaced an O-ring but it's dry again after about 100 miles. It's dripping from the bell housing so I'm sure it's the slave. The shop that did the work is 800 miles away so returning there isn't an option.

I obviously can't see what slave is used and don't want to bring it to my friend's shop to disassemble, find out what part it is, order it, ... It'll tie up a spot for a week. I pulled the trans tunnel but can't get to the opening, and the jack stands it's on aren't high enough to drop the trans myself.

The config is the Roush 427IR (351W) with a Quicktime bell housing and Tremec TKO600.

I'm sure the choices for this setup are somewhat limited, and I'd be OK ordering several slaves and returning the others.

One assertion is that my failure is caused by overextending the slave. How can that be verified?

P.S. As much as I'd like, I'm not going to go to an external slave. I got the estimate for that on the repair that failed, and it wasn't worth it.
