    http://cgi.ebay.com/ebaymotors/Mitch...Q5fAccessories
    89 SRW crewcab, Banks Sidewinder Turbo, 8 speed BTS E4OD with a Gear Vendors, Shifts smooth and positive with any load on it. Triple disc torque converter has 150 square inches of friction material, stock has just 25 square inches of material.Transcold Carrier pump helping out Moose Pump and just loven it. 4 inch Straight piped, hydroboost with a 1 5/16 inch master cylinder. 7.3 turbo upgraded motor, ported heads, intake & exhaust manifolds. ARP studs. Block sleeved on all 8. Mahle turbo pistons milled, are 24 to 26 thousands above the deck, then ceramic coated with Tech Line CBX. Line bored and balanced. Decked block.

    Finally, an auxiliary overdrive with a REAL overdrive ratio - 27%

    So why wouldn't it work with autos?

    prolly because there is no automatic disengage like a GV has with the control box. there is items like the Muncie "electric shift" for PTO's that can be adapted to the Mitchell, but it takes money for R&D that they prolly don't have. for all intents and purposes, it is a "lightweight" brownie box.

    I thought I've heard of people using a brownie box behind a C6 or Dodge 727 auto. I guess it could be tricky but couldn't you just shift the Mitchell/Brownie if you were sitting still or float the gears? Or does this risk tearing something up? I guess it's a big project, but probably easier than the brownie which was never intended to go in our trucks to begin with. At least this one might be since it was already in an OBS pickup.

    I could be mistaken on this, but I think the Mitchell is meant to be a shift-on-the-fly. I met a guy who had one behind a C6 in an F-350 crew-cab dualie, and he was very happy with the setup. Unfortunately, he ended up going the Dodge/Cummins route many moons ago...

    If I had a 2 wheel drive, I'd be very interested in that unit...

    What I wouldn't give for a 5 speed, IDI turbo, cowl induction, intercooled, 4.10 spun rearend WITH one of these boxes slapped in between the transmission and transfer case....that way I could use 4x4 if needed.
    1994 F350 CCLB 2wd. Factory 351W, E4OD and 3.55's. Slowly coming together....

    2001 Buick Regal GS -3800 Series II supercharged, Fenderwell intake, stainless headers, catless downpipe, full catback. Coming soon, reflashed ECM (overkill), 1.9 ratio rockers and a 3.4" pulley. Sub 13 second family sedan? Yes....yes it is.

    I think with newer trucks, that have the speedo sensor in the rear end and endless computers to run everything, it would confuse the shifting programs. Should work with our generations.

    I think it would fit the Chevy.....

    The statement about the Brownie not really being fit to our rigs... Nope not so... I worked on Roberts Brownie setup when he was out here on the west coast. Now thats a nice clean setup right there. The way he designed and installed it makes it look like a factory option plus.... The 15 forward choices in gears is out of this world for choices.

    buy it and take a trip to the coast to pick it up
    unlike a GV, it is impossible to blow up a Mitchell.

    Do you have 4.10's or 3.54's?

    If you have 4.10's, then I'd say go for it, from a technical standpoint.

    I'm not sure how much trouble you'd get in with SWMBO when (not if) she finds out, though...are you "just" risking castration, or is there a chance of outright homicide?
