Hello,

I have done a search and read through the FAQ. However, I still have a question about the T-5.

I have someone near me who is selling a V-6 T-5, modified with a V8 T-5 Input shaft. Now I'm planning to completely rebuild this tranny so I'm not worried about the weakness of the V6 Internals. However, my question is if World Class internals and parts are compatible with this non world class transmission. I was looking at buying a stright cut gear set, but it states that it is for a World Class T-5. Is there any way, when I rebuild this transmission that I can rebuild it to WC specs to make the straight cut gear set work?

Thanks,

Han

No.

That's why there's gear sets for 2nd design, and gear sets for 1st design. If one set would work in all of them, there wouldn't be 2 different kinds of gear set in the first place, eh??

You can't just stick a V8 clutch gear into a 6-cyl transmission. Since the gear on the V8 one that drives the countergear is a different size (different ratio) from a 6-cyl one, that means both of those gears have to have been changed. The only way to do that successfully, apart from buying a bunch of new parts and thus spending $500 on a $200 transmission, is to take apart a perfectly good V8 trans and a 6-cyl trans, lay the 6-cyl parts aside, and put the V8 parts into the 6-cyl case. Which makes NO SENSE WHATSOEVER, since if those parts of the V8 trans were good, there'd be no point in taking it apart in the first place... the right procedure would have been Sofa's Patented Eezy 2-Step Process for turning the thing you can't use into the thing you can, which is (a) sell the thing you can't, and (b) buy the thing you can; i.e. there's an intermediate step where it transmutes to and from cash. The ONLY reason for doing that is if the PO had previously spent all that "new part" money on a V8 trans, discovered that, just like all the rest of them, the case was trashed, and bought a 6-cyl trans just to get the case.

At that point, the only thing left that's specifically 6-cyl, is the tag. Anybody that would tell a would-be buyer what you just posted, is either not telling the truth, or .... something. Be VERY careful with that. Inspect it CAREFULLY. Drive it in the car it's in now and make sure nothing is wrong with it. Above all, check it carefully for leaks.

A 4th gen V6 input is 26 spline and longer than a third gen V6 input, but is still not a V8 input.

And as already said, there's no matching gear tooth count V8 input that swaps into a V6 F-body T5.

If you want to convert your car to a V6 T5, then buy one from the classifieds on here; I'd think with V8 and LS swaps going on, it would be worthwhile to buy one you know is from a third gen without made-up information.

Thanks for the reply guys.

The original owner said that is a WC unit with the tapered bearings. The input shaft is still 14-tooth, its just that a 1/4 inch was ground off the shaft to let it clear the pilot bushing of a V8.

He is asking $100 for the tranny, clutch, and bell housing. Since I was going to rebuild it anyways I thought about just putting this kit in it:

However, if this new shaft and gears aren't going to work in the case then there is no way I will go for that. My original hope was that kit would have everything I need to make the V6 a V8.

Thanks,

Han

Go third gen V8 t5 for a V8 swap.
Why? No need to piece together a clutch with the right splines. Stronger. No granny gear effect; shifts keep you in a better rpm point.

The problem is that I'm having a hard time finding a V8 T-5 in my area. Add on to that the fact that I'm leaning toward to WC unit because of the added strength and finding a V8 in my area is even harder.

That "kit" will work, and will replace all of the 6-cyl guts.

However you'll still be left with a WEEEEEEEK T-5 case, which will simply allow those $$$$$$$$gears$$$$$$$$$$ to destroy themselves in short order.

Not "A Good Idea".

If you want a stronger transmission, and it needs to fit V8 for some reason, get a T-56 instead. Pay less, get more. What's not to like?

Leave all that other stuff to people who race in sanctioned classes where the factory transmission is required by The Rules. That's THE ONLY circumstance under which that makes sense. Any other situation, you pay more but get less. NOT "A Good Idea" in anyone's book that has a grain of common sense and has thought all the way through it.
