Removing T56

I'm trying to replace the clutch in my 94Z. I can't get the tranny separated from the block. Do you have to pull out the clutch fork? If so, how do I get it out? Thanks.

You have to pull out on the clutch fork to disengage it or the tranny won't come out. Lots of people pulling trannies. This question seems to be asked every day.

What type of clutch did you decide to go with? I should have replaced the pilot bearing on my swap and now it rattles like crazy. I'm afraid I may have toasted the input shaft on the tranny.

there is a bolt in the middle of the clutch fork you have to take off. 9/16 I think. It is hard to get to, you have to take some other stuff off first I think.

Check out this directory for a bunch of pics for reference when I removed my clutch:

Pull it STRAIGHT out. YOu can pull that little housing off once you remove that little hydraulic thing. THen just pull straight out.

I had to FIGHT for a couple hours after that to get mine separated from the bell though, I think the alignment dowels were prety stuck to the holes...

Anywyas, here you can see how it pulls straight out:

Here you can see how I have it pulled out as far as it will go. I actually didn't know that housing would come off at the time:

No problem man, good luck with it! I had a helluva time myself pulling my tranny out, because it was stuck to the bellhousing. Finally got it out while I was UNDER it, had to just take it from there and HOPE I could bench press it out Luckily it was only ~125 lbs.

The clutch was replace around ~50K miles, by a mechanic for the original owner. As far as I know it's a stock LT1 replacement, but I haven't seen an LT4 to compare. My SPEC PP looks the same though, even says the same thing stamped into it...Valeo...

Yeah I didn't think that they made their own PP's...hmm...do the LT1 PP's say Valeo on them? What's the diff in an LT1 and LT4 PP? Anything we could tell?
