The Stovebolt Site Forums The Shop Area Driveline Tranny swap T5

I am looking for info on doing a T5 swap. The search says "T5" never shows up, but that is typical for low-character searches.

I went manually looming through the Driveline forum to see if I could just find it myself, but I only see 3 pages of posts going back to late October of last year.

Did something happen to the older posts or am I just derping out?

I was just derping. There is a setting for how much to show...

Nothing to see here, but leaving the post in case someone else has the same problem.

Look up Lugnutz and on his signature in red print is his t5 build page ,lots of imfo.

T5 Transmission Info Page by Lugznutz.

He's also got a Build Blog for his 1963 Chevy C10.

Moved to Drivelines. Was initially in IT Shortbus with question about archived posts.

Thanks.

Yeah, once I figured out how to show all of the posts I found his page.

Thanks to everyone that helped!

I’m here to help. I’m not on here a lot because of work schedules but you can message me.

Have you found a T5 ?

Jay (Lugnutz) is your man he got me a T5 transmission and help me out immensely. very knowledgeable and really helpful & a good dude...

I did not buy one yet. I am still in the planning/budgeting stage.

My brakes are sketchy and my pinion is roached. My goal is to fix both of those this year. If I put in a T5, that will affect whether or not I change the gear ratio in the diff while I am in there.

Though actual expenditures are on hold for a while. The CEO of the place I work announced right before Christmas that they were going to lay off 10% of the staff in Jan/Feb and cut pay for everyone else. The details of who is getting cut are supposed to be coming out over the next few weeks. After that I can work in what resources I can spend on this project.

In the meantime there is plenty of reading and measuring and thinking to do.

Happy New Year, eh? Good Grief!

If you have a SBC engine with decent HP, then a T5 with a 0.72 OD gear will work well with a 3.73 rear axle (or numerically higher axle gear).
The inline 6 engines like the 0.86 OD gear.
The 1983-93 S10 T5s have a Muncie bolt pattern where it bolts to the bell.
The 1983-88 S10 T5s should have a cable style speedo connection. The 1989-93 S10 T5s have a Muncie bolt pattern with a VSS speedometer connection.
The 1994 and newer T5s have a FORD bolt pattern with a VSS style speedo connection. An adapter plate will be needed to bolt it to a Muncie pattern bell.
Don't forget that the GMC Sonoma trucks are likely to have the same combinations.
The T5 was not mated to the 4.3L engines.
Watch THIS VIDEO. which shows the differences.

Jay, yeah I have gone through your site a few times now. I have a stock-ish 283 and a 3.73 rear end, so I think the 0.72 OD should be just about right.

Once I figure out my budget I will hit the junkyards around here and see what I can find.

Haha! I have a fresh 283 in my 1965 C10 short bed stepside and a 3.73 rear axle. The T5 has the 0.72 overdrive but I’m seriously thinking of swapping to a 0.86 overdrive gear because these 283 SBC engines like the higher RPMs. I have a 1963 C10 short bed fleetside with an inline 230 and 3.73 rear. That T5 has a 0.79 overdrive gear and does fine in overdrive.

Out of curiousity, what size tires do you have on that 65? That is a critical piece of the gearing math.

I have 235/75R15 (28.88” diameter on the 1963) and 255/70R15 (29.06” diameter on the rear of the 1965). Both drive about the same.
