Mystery T-5

pspeaks · January 03, 2010, 12:37:20 PM

My son-in-law has made me the proud new owner of a Lotus 7 frame and along with it came a T-5 transmission. When I went to the Identification Guide (link below) and looked up a 1352-066 it recognised its existance but gave no information. My son-in-law said he was told it came out of a 94 Firebird, but we all know how being told something works. I know you can't really tell from a pictures but I've attached some for reference. Does anybody have an idea where info on a 1352-066 could be found as I haven't been able to.

Well, it is definitely a Camaro/Firebird T-5, but I think they quit making that style in 1992. There should be a casting mark that indicates the year.

I didn't see the metal I.D. tag in the pics. That's the only way to know what's inside without cracking it open.

How about 1984 Firebird? That would make it a non-world class T-5. Probably wouldn't matter in a Lotus.

Does it have gear oil in it or ATF?

It's at my daughters house so I can't check it right now; I was just curious about it. I have no planes for the T-5 or the Lotus at this time as my 302 MGB-GT project fills my day, and strains my bank account, quit well. It wouldn't be suitable for a 302 anyway. The owner of our shop is bulding a 302 Lotus to use at a local road course on race day and in the future I might do the same with the frame but it's not stressed for a V8; It has a V6 chevy with it but for right now the MG has to rule. The Ford rear end is ear marked to be greatly cleaned up, narrowed a tad, and given a new home under the MG. Another question; for those of you who have done this, what demention did you use from flange to flange? Our T-Bucket 9" math would be off just a little, and no point in re-inventing the wheel.

It is from a V6 Camaro/Firebird. What does the plug on the front of the gearbox look like? If you can read "Timken" it is WC, if it looks like a freeze plug it is an earlier piece. Where did the 1352 number come from? There are more than one on the box but the one to look for is on a green and white sticker located on top. You mentioned 9" math. I'm sure you already know this but the axle in the photo is not a 9".

The company I'm associated with is a manufacturing company that has branches covering aerial photography, graphics, steel fabrication, and about five years ago we started building T-Bucket roadsters from scratch, no kit cars; we even made our own bodies. We have closed down the bucket shop and may start a 32 Coupe shop in the future as we have the molds for that car too, but I doubt we will as the profit for making toys doesn't seem to be there in our current economy. The one in the picture is mine and I made it from scratch including the body so I could say I really made it. A couple of the cars were built with Jaguar IRS but most, including mine, have 9" Ford rear ends. I was inferring that our past experience had been with narrowing 9" Fords for Buckets and we haven't done one for an 8 or 8.8. My MG is the one and only 302 project we will be doing and I was just wandering how much others had narrowed their rear ends.

I'm sorry, I got side tracked with my baby, you know how us hot rodders are! Like I say, the T-5 is at my daughter's house in South Carolina and I'm in Texas. I'll see if I can get my son to take some pictures of it and send me all the writing. Thanks for responding Guys.

Once you identify WC vs non-WC, then you can run through the ratios (output/input) to narrow the application.

pspeaks · January 04, 2010, 12:31:23 PM

I know there are a lot of gear ratios, input shafts, and internal part differences, but I was wandering, are all T-5 cases the same with the same trans to bellhousing bolt pattern?

Dave · January 04, 2010, 05:37:00 PM

All GM F bodies and V6 S10's through 1995 (V6's were 60 degree. V8 and V6 used angled gearbox) used the old GM T-10 4 speed bolt pattern (including V8 '61-'63 BOP). The 4 cylinder S-10's used the Ford bolt pattern and all post 1995 GM's (including 3.8 V6 F body) used the Ford pattern. The GM Ford pattern used a smaller index hole in the bellhousing. All Ford T-5's used the same pattern. Nissan Turbo 280's used the standard 280Z/ZX pattern. The AMC, etc used various patterns.

This looks identical to mine which came from an 84 Camaro. My tag number is 1352-061 only 5 from yours.
This makes mine a NWC version. I am using behind a 94 Camaro 3.1.

Thanks Norm, the only other T-5 I have is a 1352-155 from a 4 cyl turbo coup which everyone says won't hold up even behind a stock 302 and the input shaft would have to be changed if that is even possible. I've decided to let my son-in-law keep his and keep looking for a WC within my check book range. We have the ability to rebuild the 155 in our shop, which it needs as second gear has an issue anyway and I'm sure the syncro's need a little living care, but I'm not sure it would be cost effective.

UPDATE, another hurtle jumped! The mystery T-5 is out! I never really gave it serious thought anyway as it would be too costly to modify. I was talking with a friend and mentioned that I needed a Ford 5.0 T-5 and he said Ron, a mutual T-Bucket friend, had one he wanted out of his garage. So I bought a brand new, never installed, still wrapped in wax paper, cardboard sleeve on the input shaft, 1352-200 SVO M/S Mustang T-5 for $600; I had no idea Ron had a T-5. Sometimes luck just falls our way but we're better off letting people know what we need.
