I purcased a slave cylinder for my t56 which is believed to be out of a 98 camaro. I bought a fenco slave w/throw-out part # 13207. Well i went to slide in on over the input shaft onto the sleeve and the bore on the slave was to small. I got the harbor freight ditgital calipers out and measured the sleeve itself which appeared to measure 1.33 and the bore on the slave was like 1.15. Does this sound right?? I dont know if the slave is for a v6 5 speed car or if I have a different tranny .(it is an ls1 bolt pattern housing and has the tapped holes for the slave cylinder but they would be inbetween the bleed and the master cylinder quick connect.) So i went to autozone again to get the "right one" and it was identical to the same one but for more $ and no throw-out bearing weird huh? The bore measured the same on that one too like 1.15 or so and the drilled hole appear to be in the wrong location. Can someone help me please I want to get my tranny bolted up to my LQ4 !!! If this helps once again the sleeve that the slave slides onto measures about 1.33 on the calipers. Thanks and if someone can help me I.D this tranny Big ups to you !!!

The LS1 version of the T56 doesn't have a sleeve that the slave/TO bearing slides over. It bolts directly to the trans. Are you sure you have a LS1 T56? Sounds like you might have a LT1 style T56. Later, Dean

Your Numbers decode to a 1995 LT1 T56

Yea it is an lt1 t56, I believe someone put a viper input shaft in it, That would explain the bigger sleeve diameter it is 26 spline input too, Um When i looked it up it was saying its an LT1 and I was confused because It had a LS-bellhousing on it , and appears that it was tapped and drilled for an internal slave that would explain why the holes didnt line up with anything. There is a sleeve on this tranny, You guys have helped me out bit time !!!Thanks so for that !!The next question, Would boring out stock camaro slave cylinder be appropriate , It would only go and extra .020 to fit on the retainer sleeve . I would have redrill placement holes to bolt it to the tranny too which wouldnt be a problem so what do you guys think??? Once again you have helped me out a great deal !!! Thanks DDP

There's no hole drilled/tapped for a slave, only the stock LT1 clutch fork pivot bolt hole.

How do you know it's a viper input shaft? Does it come out flush with the block face of the bellhousing? It's possible someone machined down a viper input, installed it in an LT1 Trans, and used a McLeod slip-on Hyd TOB to activate the clutch. There's not really a good pic of the tailhousing either. Does it have a viper output shaft and/or a viper tailhousing?

How did you determine it's a LS bellhousing ? Did you buy the trans allready removed, or did you remove it yourself ?

DP506malibu

I didnt put a pic of the out tailhousing yet, I dont know that it is a viper tail shaft for sure I assumed that it was because the retainer sleeve measure 1.33. I went to the parts store and had them look up both slaves viper and camaro. They had specs on both bores, the camaro one was 30.4 mm (1.20) and the viper one was 35.4mm (1.39). I determined that is was an LS bell housing because the top tab had a hole in it and also on the side of the housing were the cut outs for the internal lines, (from what i remeber with LT housing the hole is not drilled and LT use an external slave that doesnt have the cut outs). I bought the it as a swap from a guy in Maryland with LS1 motor, the tranny was seperated from the engine but came with all of the good stuff, i have in the pics spec pressure plate/clutch disc, and fidanza fly wheel wheel, so Basically I am going to have the camaro slave bored out to 1.35 to fit the sleeve. I am sure who ever had it b4 me used an enternal aftermarket and probably kept the slave , o'well so I''ll try this , and get more pics up too, Thanks TPI

The viper never had a "retainer sleeve", they used bolt-on hyd TOB like the LS1 Fbody. Taking 0.015" out of the stock TOB will most likely weaken it and lead to a hyd blowout. Your best bet would be to follow-up with the seller, find out the setup, and talk with McLeod about getting a correct height slip-on hyd TOB. You may find that the Seller started to put this "plan" together, only to find out it can't be done cheaply, like you're finding out..

DP506malibu

Yea sounds about right lol, I cant complain though I got the whole emgine/t56 swap complete for 2,200 so thats ok but yea I will be in contact with McLeod and see what can be done Thanks for the help. Yea I figured bore that out could be don e but there isnt enough meat to do that now that I have measured it out. I'll keep you guys posted on this , thanks for shedding some light on this

If you can determine that you have a correct length LS1 or Viper input shaft, you may find it cheaper just to swap over to the correct mid-plate for the LS1 and use the OEM slave.
