    Default GM metric pattern transmission: RWD

    I noticed in list of GM Bellhousings, that from

    1984-93 RWD Iron Dukes used GM metric pattern.

    Anybody name which vehicles these were?

    Chevy S10
    GMC S-15
    Astro Vans
    1984-03 Jeep/AMC/Chrysler 2.5L/150

    Any more RWD vehicles?

    If you're looking for a RWD transmission with the GM metric pattern, all V6 and 4cyl F-bodies from 1982 on had the metric (FWD) pattern. Incidentally, the same is true of most 90's Isuzu's. The best way to answer the question is to ask what you need the information for or what you intend to build with one of these. Me, I want a Chevette with a Northstar bolted up to a T-5. The Chevette was available with the T-5, and F-bodies had metric pattern T-5's. Add a custom flywheel and engine mounts, and that's a neat little car, no?

    I'm fishing around now...getting to know what to look for....if I do this project.

    I was thinking about dropping an older GM V-6 (2.8) or V-8 (267) motor and tranny into a 1982 244 Volvo, when it fails (when repair cost is too high when engine/tranny breaks).

    I would like to drop a GM Iron Duke motor in it, but mating to a THM200-4R transmission (or 700-R4 which I both have) requires an Iron Duke with with Chevrolet's V8 engine bellhousing pattern, which I don't have, but I do have two Iron Dukes that mate with GM metric pattern bellhousing.

    So, if this happens, I want to find a "cheap" transmission, which Auto 3 or 4 speed with lockup would be desirable (I can play with tire size so either 3 or 4 speed will work) if I use a Metric transmission (RWD).

    Hence, when I visit the bone yard, I want to examine what is available there, and know what to look for..

    Pretty much your list is complete, but the number of V6 F-bodies in junkyards should be impressive. That's where I would look. S-10's should also be common, so those would be atop my list.

    Hah. That's a chevette? I remember riding around in one of those when I was very very little (1990, 91) The grill looked familar. Did oldsmobile do a cover of that too? Was the Olds Omega there answer to the Chevette? We had an omega too. Much later though. It was an 84. Total POS. Overheated constantly.

    .
    Many of the junkyards who trade on internet trash vehicles past 1994 for scrap metal.

    Even in Tulsa area, you will find yards with limited vehicles past 1994.

    For newer transmissions, say 1999, they will fetch some $800 for a good one, which is about going rate for a rebuilt one, more or less, depending upon where you live.

    Salvage yards ain't what they use to be, before internet. And many of these "computer operators" don't know squat about vehicles....its just part names in a computer, and the yard dogs go fetch/send it.

    Might have better luck on ebay, or going to auto forums where these vehicles are...otherwise, once salvage yard gets their hands on that "junk to be scrapped," when you walk in and want it...my, my, how that junk is now worth more than scrap value...much, much, more...
