Budget T5 Transmission Upgrade for your classic Chevy or GMC - What you need to lose the 3&4 Speeds!

[@deansworld2591]

Hey I just got a 64 C10 and am going this route immediately. So informative and helpful. My first project truck and am getting rid of the 3on the tree . You saved me a lot of stress 🤙🏻

[@shortcutgarage]

Hope it helped!! It’s a great upgrade!!

[@deansworld2591]

What is the exact model you used? Year and so forth !

[@shortcutgarage]

@@deansworld2591 not sure, was a swap meet find but 83-87 have mechanical speedos, 88-92 have electric. All will work, just the Speedo to contend with if it bothers you. I just use an Amazon GPS for $30

Awesome just picked one up with a electronic speedo . Ima watch this video about 10xs before I make my move😂

Absolutely love the video I have a 63 C10 that I am wanting to do that too very informative thanks a lot

[@shortcutgarage]

You’re welcome. I’ve done a few of them now. Very simple

[@Schetmesa]

Do you have the bellhousing mounting pads? My 63 does , I gues I keep those and add a rear trans mount? Thanks

[@frankcolmenero1880]

I had a question I’m using a t5 on a sbc350 and I already got the bell housing but having issues finding a cheap clutch set up for the 14 spline s10 trans to match up if I swap to the gm 10 spine like you did couldn’t I just use a gm clutch set up do I still need to shorten the shafts too

[@shortcutgarage]

@@frankcolmenero1880 yeah it’ll have to be shortened. The shaft I use is a jeep shaft. I know some guys have had luck with a t5 clutch from a safari van or Astro van. May want to try that, maybe even a v6 Camaro or Firebird from the late 80s or early 90s

[@frankcolmenero1880]

@ is there a specific shaft to order and what was the cut messurements on both plates

[@jodypierson3137]

Is there a specific reason you swapped to the 10 spline? I was under the impression you can also use a clutch for a Astro van with a 4.3 liter, it uses a 11 inch disc with 14 spine and 1 inch diameter shaft, lop a quarter inch off the pilot bearing part of the shaft and shorten the release bearing collar an inch, I spose you would have more clutch choices going 10 spline, but at 300 hp would it really matter? Great video, good information thank you.

[@shortcutgarage]

Good question, typically I use them in place of an existing transmission. For example maybe a 66 C10 with an in-line six, 3 speed Muncie M18, or maybe a 4 speed, just easier reusing all the existing stuff and you can still simply order the “correct” stuff for your vehicle (clutch, flywheel, throw out beating, pilot bushing, etc). Maybe I’ll try the Astro Van angle on the next one, I’ve been having a few people ask, maybe that’ll be next!

[@daleolson3506]

Speedway motors has a disc that works. Need to grind a little and measure to get it to work. I put a spacer in my bell housing too

[@luckyPiston]

Jody , Some flywheel / pressure plate combos (153 tooth) use 10-3/8 or 10-1/2 inch disks, those are harder to find in 14 spline , i think thats the main reason,,, the 11" disc u mention is that with a 168 tooth flywheel ? cause i think ta run 11-12" disk ya need tha bigger flywheel ?

[@matthewjacobs-q9v]

Great video! Only questions I have are, why did you need to swap the input shaft, and also how did you determine why and how much you needed to shorten the shaft and the collar?

[@shortcutgarage]

The length of the input shaft needs to match the set up I was using which was the bellhousing from a 3 or 4 speed Saginaw, SM420 etc which has a shorter input shaft than what I bought. Same splines though so I can reuse my clutch. Same deal as the collar. Just matches original.

[@maggs131]

I love dogs but that yapping would make me crazy. The flat bearing you didn't know the name of in the input shaft was a thrust bearing that takes ➡️⬅️ type forces

[@shortcutgarage]

You are correct! I looked that up after the fact……how’s the video of your new truck coming? Any teasers

[@ironheadbro]

I have a 1965 C20 283 with the original 4.56 rear end . Trying to find a rear end swap that is budget friendly has been discouraging. This T5 installation seems to be promising compared to a different rear end? When you put this T5 in your C10 take us along for the viewing. Thanks

[@maggs131]

What are you wante to swap out and swap to?

[@ironheadbro]

@@maggs131 swap out the 4.56 to a 4.10 at most or better yet a 3.73 or 3.90.

[@maggs131]

@@ironheadbro unless you are towing or want terrible gas mileage I'd go with 3:73. 3:90 isnt a standard option. Next highest was 3:40

[@ironheadbro]

@@maggs131 My research is showing that in order to go with those options I have two put a complete rear axle assembly in my truck. That’s a cost I didn’t want to incur.

[@WilliamMunny-d8s]

im just a shadetree mechanic, not mechanical mathemagiciianal, so what does the ,72 or .86 overdrive ratio of the T5 reduce a 4.56 rear gear ratio to about? is it just straight multiplication 0.86 x 4.56 =3.92 equivalent rear gear? or if its .72 OD then .72x4.56=3.28 new efective reear gear? or is the math more complicated than that?

[@shortcutgarage]

Instead of your final drive being 1:1 which is the norm for 3 or 4 speeds it would move you to say .72. So instead of rolling at say 60 mph, 3500 rpm, you could do the math at .72 x 3500 and you’ll see you now roll down the highway at 2520 going the same speed.

[@seeunow44]

I have a 91 S-10 with T5 behind iron duke…. I wanting to put T-5 behind 4.3…. What is needed?

[@shortcutgarage]

You’ll need to swap to a V6 bellhousing, east enough to find I would think. Everyone leaves them behind at the wreckers when pulling the T5 for inline six and V8 applications

[@joelavender8989]

How did you determine the shaft length and bearing housing length to cut.

[@shortcutgarage]

It’s a common upgrade, the info is out there on a C10 Forum I was following at the time. I’ve since done three of these. It’s solid

[@matthewhipps9273]

I would love to do this for my 1966 C10. The only problem is that I can't find a T5 locally. I did find a 80s S15 4x4 with a 5 speed. It's got hornets nests underneath it, so I can't look under to see how the tailhousing works. Can the t-case simply be removed and the housing reinstalled?

[@shortcutgarage]

Not too sure but I don’t believe that works, I’ve always found the 2WD variety. The cheat code for finding one is a wanted ad, marketplace, Kijiji, Craigslist, S10 groups. They are out there and they are cheap.

[@matthewhipps9273]

@@shortcutgarage Thank you for your quick reply! I'll keep looking. Ever heard of someone doing a 4L80E with a TCU behind a L6? Might be my other option.

[@timothyorum6529]

Are the teeth on the inside of the input shaft the same no matter what engine it was on?

[@shortcutgarage]

The main difference on these trannies was the final drive ratio. The input shafts have all been the same from what I’ve seen and can find out yes.

[@timothyorum6529]

Outstanding. Thank you

Great job Will this setup fits on 65 mustang 6 in line?

With the right bellhousing and clutch it will

[@joelavender8989]

What kind of throw out bearing did you install? I have a 88 S10 that came with a T5 and iron duke and it’s locked up. Found a Chevy 4.3 that takes the same bell housing as a SBC and want to use the T5. It already has hydraulic clutch set up in the truck.

[@shortcutgarage]

I used the existing throw out bearing from the 3 speed. Worked just fine but the S10 one would work if your using that fork

[@19654406]

'64 C 10, 3 speed Muncie...putting in the S10 T5., behind a fresh 283.. how does the transmission mount at tail shaft to cross member? any modification needed?

[@shortcutgarage]

Just like the Muncie, there is no mounting the tail shaft, not necessary. Some guys do modify an S-10 mount but I don’t think it’s necessary unless you have a ton of torque. In which case there are better choices for a transmission to stand up to that torque. So short answer, there is no need for it. The bellhousing is mounted to the cross membership. Transmission is bolted to the bellhousing. It’s enough.

[@timothyorum6529]

Did you also have to shorten your driveshaft? Mine will be going in a short bed....behind a 327...do you think I'll have to shorten my driveshaft?

[@shortcutgarage]

Definitely. I actually got a driveshaft from an S10 and used an adapter u joint for the rear. I have also shortened them too
