I rebuilt a 2.5 in an 89 S-10 2X pickup 5 speed.
The truck is wrecked but the engine is fine.
I bought a 84 S10 4X4 with a 2.0 and a 4 speed.
Will the 2.5 bolt up to the tranny in the 84 without too much trouble.
Probably gonna try to swap the computer and all over to the 84.
Any suggestions??

swap the whole combo - engine and trans

I don't think that the 2wd transmission will fit in the 4x4.
I would imagine that the engin should fit, as long as they're both 2.5 L

OOPs!, No thinkin' about it, your right. Didn't catch that 4X4 thing, only saw the 2WD. The tail shaft on the tranny is wrong.

The 4x4 is a 2.0 and the 89 is a 2.5.
will the 2.5 bolt up to the 84 4 speed tranny?

Off the cuff I would say yes, but I have never had a 2.0 out and saw it. I would want to keep the 5 speed so if it were mine, I would go to a salvage yard and pick up a 5 speed that will take the tansfer case. Also, I would drop a new clutch in since you have it out.

In my area, that tranny would run $150 - $200.
