T5 Swap

[rmsteph828]

I am posting this in regards to the first section of the Complete T5 swap.

"This discussion is about swapping an S10 T5 (in my case, into a 66 C10) – if you have a Camaro T5 then you don’t need the spacer plate or bearing retainer index ring extender outlined below, just drill out the 4 mounting holes on the trans to ½” and bolt the T5 in with the appropriate clutch/pressure plate combo for the trans (i.e. a Camaro clutch kit) and you’re good to go. But, of course, the underlying reason folks like the S10 T5 is the forward shifter mounting location that works so well with truck bench seats."

I took this as truth and found my self a 92 Camaro V6 T5 to drop in my 1964 C10 chevy 230CID. I planned on obtaining the S10 tail housing to move the shifter farther forward. Unfortunately the swap has not been this straight forward as illustrated above. First off the v6 camaro T5 has the ford bolt pattern not the GM(with the ears). Second the spline length is different from the munice sm420 that came out of the C10. The Muncie sm 420 has a spline length of 6.5" while the camaro wc t5 has a spline length of 182.1mm(7.16929") resulting in a difference of .66929". To combat this I bought my self a v8 camaro t5 wc case with the GM bolt pattern(not cheap). I plan on milling myself a spacer plate to make up for the difference. I am posting this to find out if any one else has ran into my same problems and for anyone else planning to attempt this swap.

Thanks

The spline length of the 92 camaro I found in a book How to Rebuild and Modify Your Manual Transmission (Motorbooks Workshop)

rmsteph, not sure I could have been more thorough in my post, and I take minor issue with implying it's "not truth"... My goal was to help folks with the issues I encountered when installing a T5 in a V8 truck that had a 3-speed, not an SM420 - but I had to learn a lot myself before I purchased a trans as well. Anyway, I'm sorry you're having problems. However, it may not have been wise to plan your entire build off of one sentence in a 5 page thread - I believe you may have benefited from reading a little further or a little more of the detail perhaps. As stated in the thread (later), you need a pre-92 trans or it will have a Ford bolt pattern. It has nothing to do with whether it came from a V6 F-body - your issue is the year of mfgr you chose. I didn't know this either and learned it as the thread developed - that is why it's posted later by another helpful member. That tidbit is, however, outlined in some of the links I provided.

Spline length differences are outlined in the thread, but the variables between an S10 and an F-Body (and apparently the differences you're stating between a V6 and V8 F-body?) are the reason I mentioned you may want to make a 2D mockup of your disk/pressure plate/release bearing stacking height. It's the only way to know what you have.

I am curious how you ID'ed the trans you bought? Did you physically pull it from a 92 Camaro or were you going by a part number on the trans?

Thanks for posting and letting others know of the problems you've encountered - it may help someone else out with the same swap.

Also, so you know, your identical post on my thread was visible, probably no need to start a duplicate post like this.
