Thread: Dual Transmissions

  1. #1

    Default Dual Transmissions



    Although it boggles peoples minds, this is the path I'm heading down.
    I thought I'd share some of the reading I've been doing.

    Csudman's Truck (He also sells adapters now)

    Here are the adapters that he sells

    I have read about it over on pirate when i first saw them doing it. I'm really curious to see how your truck comes about.

    I actually got my adapter from a guy named Jason in Littleton (Was Automotion now is Repost, on Pirate4x4)

    I'm going to run a L52 in the front, W56 ******* Tranny in the back.
    The W56 has '88 Internals, '94 front housing and an '88 G54 rear housing(To mount to my forward shift t-case).

    The W56 is still on my workbench in pieces(It had broken shift linkage that I fixed).
    One of these days I'll get it all together and put in.

    I need to lift the truck first though.

    I also need to massage(With a big hammer) my extra gas tank to get it to fit.

    Wild! I had never heard of this; learn new things every day. Where does your transfer case shift knob end up?

    Pretty close to the hip.
    Here is the placement in MyAnarchy's truck


    Mine will be further forward because I am using a L52 for the front tranny(It is ~6" shorter), and a forward shift case.

    No! The dual t-case lever would have to be shifted be the person in the back seat(in a 4runner) or bed(in a truck).
    Plus I don't think I need 848:1 or even 412:1 gearing.
    That would be CRAZY slow.

    Ok since you asked about dual t-cases.
    Here is a guy that is running 5.0?? in the t-case.
    I don't know which trannys he is using, but in my tranny setup, if I ran 4.7s in the t-case, that would give me 315:1 1st/1st/low or 390:1 in Rev/Rev/Low

    Do you know what the link is to the site for the adapters for sale? Tried to find them. No luck.

    Jeff

    Go to the Toyota FAQ in the Toyota section and you should find the dual tranny stuff. If it isn't there, it is probably posted on pirate4x4 somewhere.

    Here is a pic of csudman's rear driveshaft.


    Some people have been able to do a direct driveshaft swap(front in the back, back in the front)

    Yeah, I know that the entire drivetrain should fit under my single cab. I wasn't all that worried about angles. The CV should help too if I decide to have a shaft made. Will look at all my options along the way.

    I browsed all over for Csudmans adapters. Neither Google nor Yahoo found them. I didn't find any link in any of the dual builds either. Appreciate a link!

    Myanarchy has a standard cab and swapped the front driveshaft to the rear. He moved the rear axle back an inch. Here is a picture of his rear DS from his build.
