For arguments sake, let's assume that someone acquired a '96 GMC Sonoma truck with the mighty 133 inch inline four and the T-5 manual. Understanding that such a transmission is probably constructed a little lighter than some other T-5s, and that the smallish clutch would not survive long, would such a transmission bolt directly to a standard SBC V-8?

Let's also assume that the engine was mildly built for the street, and would turn at about 6,800 RPM when necessary. How long will the transmission last between such an engine and the 3.73 rear end?

Just askin'...

Well, without actually looking at one, I'd have to say that they have the same bolt pattern as the 2.8, which is similar to the front wheel drive. Seeing that the 2.2 started out as a purely front wheel drive engine, I would think that they kept as much as possible the same. Many of the other things I've seen on them are the same as their FWD counterparts. I think even the heads interchange.

I miss the old 2.5, even though it was a heavy sucker, and didn't like to rev, it at least had a little bit of torque! THe anemic 2.2 just flat out sucks! (just my opinion!) I still would like to see a rear-wheel drive Quad 4!

So it sounds like the theorhetical solution would be to use a spare Super T-10 and forget about the overdrive? Big clutches for the T-10 are widely available.

Hypothetically, it would have been nice to keep the R's down while on the road just cruising. Obviously, anyone squeezing a 355 in an S truck isn't looking for 35 MPG, but engine longevity might be an issue.

Thanks.

Yea, im fairly sure it's not the corect bolt pattern. But lets say it fits . I dont see why it wouldent hold a mildly buily SBC with 3:73's. Theres A guy in Woodland Park Co, cant think of his name at the moment, he works with 4 banger 2.5's & 2.4's, 90deg 6's 2.8's, 3.1 & 3.4's and 4.3's. These are used for drag cars and are backed by t5's only. His cars run in the 10-12's, In mile high altitude thats flat hauling. If the smaller cube engines can produce such great numbers they have to be putting out alot of TQ&HP right? So if everthing bolts up I dont see why the t5 cant handle the power, or he just dosent care about blowing them up.

Oh well!

 

You could also grab a T-5 from behind a 4.3 S-10. That is what they had isn't it? Not that POS Getrag.....(I only say POS because I had to rip one apart at the shop today!)

As far as that goes, you could always find a T-56!

I'm still waiting for a particular LT1 engine, trans, wiring, computer, etc... to "become available" to put in my '88 S-10 extended cab! That would be nice! I just hope the budget can hold out until they are ready to sell it!

You know that a SBFord engine, especially with the short water pump and timing cover is much easier to put in a short engine bay, dont you?

 

Max,

Thanks for the reminder about the 302s. The SBC is fairly trim with no fan and fairly tight headers. I suppose I could go with the LT1 if I wanted both space and power....

The '95 and later S-trucks seems to have a couple more inches between the rails than the older S-trucks. Even with AC on the S-10 the bay is long enough to get a reg'lar ol' Teepee Eye in there with an electric fan. I presumed a short pump SBC should go very nicely. The tape measure says it will fit, but be within' 2" of the radiator. Maybe Opti-Spark isn't that bad after all.

2"? May as well park a Caddy in there while you are at it, thats plenty!

 

How about option 3? Find a T-56.

 

I recently had to replace the tranny in my Z and was told that the T-5 from an S-10 would never work because the bolt pattern is different. In the Camaro's, the tranny is twisted off to the right hand side which shifts all the bolt holes. The S-10 version of the T-5 is straight. Does this make sense to anyone else but me? Basically the answer is no, the T-5 from an S-10 doesn't fit. Just wanted to throw in my 2 cents.

 

Vader,
The 2.2 definitely has the "2.8 bell housing" flange. I don't see why you couldn't just get a new bell housing, then slap in a V-8 with a V-8 F-body spec clutch. I know they made bell housings for trucks w/T-5's, that mount them "staight up" not ****ed over to one side like in an F-bod. I know because when I was converting my T/A from a 700R-4 to a T-5, I got most of my parts from salvage yards. On my first try I got the wrong bell housing. Its was for a truck, and it didn't have any angle to it.

For a clutch, just get one for an F-bod V-8 application. I think all GM T-5's have the same spline count on the input shaft, but I'm not 100% sure. I do know the V-6 T-5's have the same sline count, despite a totally different bell housing and smaller clutch.

And I think the T-5 would hold up fine with the total lack of traction you will have

 

Something tells me that the input shafts on the little 2.2L engine T-5's is the smaller with less teeth. and the stuff in it's not"industrial strength"

In which case. it would last about one throttle application before something grenades.

BUT... i've been wrong before.
I'd say the EAsiest, non invasive way is to get a clutch from a 2.2L S10, and a clutch from a T5 Camaro, or truck or whatever, and look at the splines, if they are the same, give it a shot, if not ehhhh.

On a side note ran into a similar problem with a VW truck not to long ago.
the truck had a Scirocco drivetrain in it. and the clutch blew up.
the kid wanted a clutch, come back a few days later to do it he's got a trans to as well, wants them bothe in, Not knowing much about VW specs on their transmissions, the cases were the same, and with his assurance that the parts he bought were right we get to changing. put the new trans up and in, go and put the clutch on it(one FUNKY SETUP) and it goes right on, no fighting at all.
problem is, the axle shafts won't go, the Inner CV's are different.
the~something's wrong bug~ is creaping in now., But with the assurance that this will work we go ahead.
get everything squared away. fire it up.. the most Ungodly noises coming from the trans, realized it had NO gears, we shut it off in aobut a minute.
pulled it back out.. the splines in the clutch were destroyed. the in put shaft was fine.
Same tooth count, just abou 1mm smaller input shaft.... which we came to find out is the difference between the rabbit transmission we were assured would fit, and the Scirocco trans we removed...... CAse was letter perfect identical... guts different.

i guess the moral of the story is. leave weird *** german bastardized stuff to wierd *** german bastardizer mechanics.

And. car companies will load one identical case with good stuff, and one with pure crap

 

Here in Virginia, one of my buddies friends did a very sweet motor/tranny swap.
He had a 2000 Sonoma I4. He bought a 95 LT1 and T56 from a wrecked Formula.
They installed the motor and tranny and the setup looks sweet. Took them a little over a month to get everything bolted in. I'll see if I can get some pics of this swap.

Wow, I've never seen Vader, actually ASK a question, I just assumed he new everything.

 

FWIW, the V6 T5 trannies spline count is 14 with a 9" disc, where as the V8 T5 is 26 with a 10.4" disc.

Thanks for the excellent responses. I've never played with the 133 engines or transmissions. Looks like I might be starting soon. There should be plenty of space if everything is arranged properly. If this flies, I'll have a few photos and hard lessons for the experience.

Wait just a min here,

1, Why not go with a V-8 T-5 in the first place?

2, At the shop I'm working at right now we have a V-8 S-truck (our beloved parts chaser). About a 300 hp 350/TH350 combo with a 4.10 rear. All I can say you don't need much to make these trucks fly. At 40 mph I can floor it and break both rear tires loose.

3, I'm liking the 289/302 idea... The adapter to use a chevy trans is available and seen it done, Dare to be different.

 

Aaarrrgghhhh!!!! Somebody said the "F" word!

I can't help it, I'm a die-hard chevy fan! I couldn't even think of a Ford engine in my S-10!

But seriously, that would be interesting.
