here is the backround...i had a shop do this install for me on top of them installing some longtubes and making a custom y (which turned out good) but the clutch doesnt want to engage i'd say about 95% of the time...now theyre trying to tell me that i need to buy a corvette slave cylinder (because the one i bought was a ls1 gm replacement) and have a shim made...does that sound right??? theyre also going to charge me for the labor again....(probably not full labor, but still)....my car is in worse shape driveability wise than before they installed it...

As far as I remember, shims are only used when the clutch is engaging too low. If it's not engaging 95% of the time, I'd say maybe the slave is bad or the hydraulics weren't bled correctly.

^yea i agree that sounds like some bullshit. if you "have" to have a special slave they should have told you that to begin with. they are probably just looking for a reason to get it open and fix their mistake at your cost.

On one side of the equation, if the mistake is due to the customer, then the customer should pay again for the labor. On the other side, you would think the shop would have some experience/knowledge in this type of work, but this could be your problem to for not doing your homework. JMO

thnx guys 4 all the help by the way, i REALLY appreciate it....here is an update. i decided to try and take matters into my own hands, because i feel that the issue was bleeding and the guy at the shop insists on getting a shim made for it. so i sat in the car for 1hr and 20min lol and used the only method i know how (to bleed) and pedaled the clutch and paused and pedaled till i was bored out of my mind. it helped BIG TIME, i drove it and it was shifting smooth into every gear, but about 5 min into the drive, getting into the gears started to get a lil harder, and i tried reverse again and again it started grinding again????!!! wutsup with that???

There are 2 ways of doing this:
1. Have a friend work under the car to open and close the slave valve.
2. Drill a 1/2 inch hole from inside the car, right across from the slave, to gain access to the valve yourself.
If you only pump the clutch a few times, your only moving the air in the lines around, but it's still in the system.
There's a set of instructions on installuniversity.com that you can use.
Another dumb question, during the time that it worked fine, how did the clutch engage? It should feel just like stock, hence no need a shim. The guy at your shop is a JACKASS.
