Hey all, I read the sticky all about the t5 and saw mentioned a few times that the v6 t5s input shaft is longer than the v8s one, can anybody truly verify this for sure, as I’m in the process of doing this swap and it’s all bolted in and done but it’s acting like the clutch won’t engage, I’m at my wits end! I’ve changed everything, new throwout bearing, new fork and pivot ball new pressure plate, using the proper clutch to get the v6 to work with a 14 spline center. I’ve even replaced the hydraulic system. And before you say so, yes I have installed the throwout bearing properly on the fork and it is all greased up properly. The only thing I can think of now is that the input shaft might be longer and maybe it’s pushing up on the crank so much that it’s forcing the trans to spin too?

 

Yes.

 

[QUOTE=jmd;6410948]Yes.[/QUOTE


even with the input shaft being longer would it still be able to get flush with the bellhousing and mount up? Because mine is bolted in all the way

 

I’m going to shim the transmission out from the bellhousing this weekend, I’ll update on if it worked or not.

 

Yep. Loosen 4 trans bolts. Remove one, add washers, replace. Repeat. See if it helps.

 

Well I shimmed the transmission and it’s still doing it, the clutch absolutely will not disengage. I might try fabricating a longer slave cylinder pushrod for it and see if it does the trick.

 

Well I made 1 longer slave cylinder pushrod and I’ve gotten the clutch to sort of disengage I can get it into 1st, 2nd and 3rd no 4th 5th or reverse, I’m thinking it needs to be a little bit longer, my only question is why do I need more throw? Could it be an aftermarket clutch? I’m using a luk flywheel, clutch and pressure plate.

 

If you have all correct parts that aren't worn or broken, you shouldn't need a modified slave cylinder.
Are your pedals from a third gen? If it has steel support rods that go to the master cylinder hole, they should be. Stamped support is 4th gen pedals.
Is it possibly a V6 clutch fork? I don't know what the difference is from a V8 third gen clutch fork, but it's different. There were early 4th gen clutch forks on V6 models.... you'd only have proper function from an 84-92 V8 fork.
Flywheel dimensions, and clutch parts matter. Whatever 14 spline clutch disc you have may be too thick. Or the pressure plate finger travel may differ. Or the clutch may be otherwise defective.
If you back up and make sure you have matching third gen V8 parts, you'll probably figure out why you're wrangling for a fix.
I'm grasping at straws, so welcome to the internet. Or something.

 

okay, I’ll list the stuff I’ve replaced with it, I’m using a hay’s flywheel rated as oem replacement, I know it’s fine as it’s the exact same dimensions as my stock flywheel I pulled off, the pressure plate is from luk it’s for a v8 camaro of my year 1987, the clutch hydraulics were all replaced aswell from a company I got it from that is one source I’ve been thinking about but I’ve been thinking about the clutch disk I used as the conversion for a v6 it is from luk aswell but it’s for a 1986 2.8l v6 gmc s10 if I recall correctly year might be different. But I bought that because of what I read here on a board for it, I’m wondering if that might be my issue for it, question is what clutch can I swap in that would be a guaranteed fit for the v8 camaros setup? could I run a v6 camaro of the same year as mines clutch? , the clutch fork and throwout bearing are indeed a v8’s and I also replaced my pivot ball with a brand new one that is for a v8 camaro from summit.

 

My guess is the clutch only thing is I don’t even know what I could buy and swap in that’d be a guarantee fit for it

 

I also appreciate the conjecture with you it’s great to be able to converse with others on issues with this car, this forum has been a real life saver for me a lot of times.

 

Also forget to mention they are 3rd gen pedals this car came from the factory a manual

 

At this point, the disc seems like the odd man out and possible culprit. Off the top of my head, I thought that disc was smaller dia. for that application. That's secondary to the disc possibly being thicker than stock, which could lead to release failure.

To cut to the chase, pull it, see if the friction area thickness matches a parts store V8 10.5" disc and then find a local brake and clutch rebuilds. While they mostly do truck stuff these days, you could see if they could:
check your flywheel disc pp assy. for proper release.
possibly find an Astro van disc that is correct for your flywheel / pp and matches spline.
Or take the right disc and re-hub it to match spline.

 

i gotcha, well looks like I’ll be Looking for a good transmission shop near me in the mean time I’ve got plenty of work on this thing to hold me over, clean up the engine bay (loose wiring, reset everything in the interior, tune the edlebrock carb I’ve got) I appreciate the help.
