Dave, I think the S10s have a New Venture transmission in them. It's a 2 piece case (the last two body styles with the 2.2 EFI and 4.3 CFI/MFI options) instead of the standard bell/gearbox/tail housing configuration. I believe it's an NV3500?

Regardless, I was informed by my local junkyard that in order to change the truck to a 350 or 4.3 from a 2.2, you just change the front half of the trans case, because the internals (gears) were the same. Not sure about how true it is, because I've never had one apart.
