    What auto trans & t case setups fit in our early CJ5s? I'm set on a V8 swap and would like to run an auto. Not set on brand(GM or Ford, possibly Dodge) quite yet, just wanna know what fits and what don't.

    Thanks- John

    C-4 or TH-350. Anything else is TIGHT. Can be done, like the TH-400 but the rear driveshaft tends to be real short. All depends on what engine and the useage of the vehicle.

    Another thing that may be an issue is that my jeep is lifted, I believe its the 4" skyjacker springs. I am not really into trails as much as mountain roads, street, and maybe sand. I do want to be able to use the power if I want so I need to stay away from too steep of driveshaft angles as I've heard they will break.

    as above 350 or C-4 with an D18 xfer. The D18 has a lower rear output than a D20 and is shorter in length than a D300.
    The TH350 adapter with new output shaft will also play into length too. Adavanced is shorter but require a "v-6" u-joint or grinding on the case. Novak's "short shaft adapter" is a little longer and might require pan mods.
    With and auto you will still have a short drive shaft with a V-8 but it's do doable.

    Driveshaft angle is always a consideration. If you need to, you can put spacers between the center crossmember and frame, which reduces the driveshaft angle. You can also limit your rear wheel travel to prevent excessive angles. The Tom Woods site has a good primer http://www.4xshaft.com/index.html - look at "Geometry 101" under tech.
