The Stovebolt Site Forums The Shop Area Engine Shop Isuzu tranny ?

I have a chance to buy a 1988 Isuzu 5 speed tranny and would like to know if this is the same tranny as an S10 ? I want to put it in my '65 Chevy C10 .I tried to pull up the www.inliners.org site as I know they have a t5 page that lists all the tranny's ID numbers , but I couldn't get it to come up ? I have a copy of the list somewhere but I don't know exactly where it is at this moment ? Can anyone tell me if this is the same tranny as an S10 ? Also , is it the one with the integral bellhousing or separate bellhousing ? I need the separate b/housing . All help will be appreciated .

I'm relatively sure that it is not the same, speaking as a former but brief owner of a 1988 Isuzu pickup.

Here's The tag #'s from Mongo's Garage. I saved for future reference. Hope it helps you decipher.

Didn't Isuzu actually make some of the earlier F-rd Ranger trucks? I would think that it would be more like a Ranger tranny.

There are some Isuzu transmissions listed on the print out of T-5 transmissions. A quick check of the tag number on the transmission against the list would show if it is a T-5 or not. It is possible it could be a T-5.

I believe that was Mazda.

Even if it is a T-5, it will probably not interchange with the Chev. unless the Isuzu had a Chev. engine.

I had a 1991 Isuzu Rodeo with a 3.1 Chev motor T5 and chev.
rear end from the factory new! FACT!

I bet it wasn't a Chevy engine, the 3.1 was only made as a front drive engine, never for rear drive. Every Rodeo I've ever seen had an Isuzu engine in it, and a freind of mine that built them never saw any GM engines in the plant, either. They also all used Aisin rearends.

My 1982 S-10 has a 1.9 liter Isuzu 4 cyl. Not sure how long they had relations. But they were cozy in 82. I would be intrested to know the verdict.

GM and Isuzu worked together since at least '72, when the LUV came out. Isuzu did provide 4 cylinder engines for the early S10s, in both gas and Deisel. I seem to recall that Isuzu did build CKD Chevrolets and Buicks in Japan since sometime in the mid-20s.

See next post...

The 88 Isuzu's had 4cyl Isuzu motors (I had one for 13 years), and if I recall correctly, also could be had with the 2.8 liter V6 that GM put in a bunch of different vehicles. I am talking Troopers (SUV's), not pickups. They were badged with a "V6" badge on the back right-hand side of the doors. This may have started in 89, but somewhere in there they had the GM V6's for several years until they restyled the Trooper and Isuzu made or sourced a DOHC V6 for them.

Whether or not the transmissions and engines all had a Chevy bolt-pattern, I have no idea, but I do know they had the GM 2.8 motors for several years.

Oh, GM and Isuzu are still cozy as the original Duramax diesel in GM's heavy duty trucks is an Isuzu designed motor. I think Isuzu may have produced the motors when they first came out, but I don't know if that is still true.

If the T-5 doesn't bolt up to your 65 bellhousing, you could use an adapter plate.

Actually I have seen a few and knew one owner that had one with a factory GM 2.8 V6 in it. Later GM came out with a 3.4 rear wheel drive engine as a replacement. You could put them in Rodeos or early Jeep Cherokee. He had the newer 3.4 installed and it ran like a scaulded hound. You can still buy that engine from Chevrolet. It has 40 more hp and way more torque than the ole' 2.8. They were mainly for carb engines but they told me at the dealer that a cam swap would make it much better for TBI. Otherwise you would have a bit of hesitation when you first take off. Aside from that they ran really well. Almost bought one. His was an automatic and the others were stick except for one. Later they put in their own Isuzu engines in them. The 3.4 rear wheel drive was better than the Isuzu engine. Just some info. Plus all you need would be a set up from a Rodeo or Trooper that had the V6 emblem and had the GM engines in them.
