    I'm going to rebuild my 904 soon and want to know who makes the best rebuild kit?

    Also who's manual reverse VB do you like?
    I notice a few say not for trans break. What's up with that?
    I would like to be able to upgrade to a TB later with out buying another VB and the 900 dollar TCI one is out of my price range for now.

    TCI-129000 rebuild kit from Summit about 200 bucks. I'm pleased with the positive shifts. Quality components too! 65'

    I have used Cheetah reverse manual VB a couple times and like them. For milder builds I like to use the transgo shift kit. I think TF-2 is the one I usually get.
    Not much difference in most kits other than type of clutch plates used. The biggest thing is to check things that are not included in the kit like bushings, sprag, etc. The rear band usually has to be purchased separate but some kits do come with both.
    Most kits come with the plain jane tailshaft seal. I prefer to buy the correct one with the boot for mine. They cost a few bucks but well worth it.

    the best kit.....if you are rebuilding a 904 for performance ....your run of the mill kit is not going to do it for you...

    I would put 5 clutches in the front drum...that take 5 thin disc.....068 or .061 thickness...same as the rear drum...
    replace the big spring in the front drum....24 spring kit...or opposite wound spring from ATi....
    replace the servos....use billet servos....sonnax makes some inexpensive servos... or then is a billet rear servo from Randys for about 90 bucks...
    you need thrust washers....bushings....teflon or steel sealing rings...only a couple of companies make them so dont fall for the reboxed parts...
    transbrakes....I have 4 of them in use....all are Tranzact of Indy....1st was bought back in 1993 and still in use....they sell for around 600 bucks...
    converter....well..none of our converters were made for transbrake...we use a two step were the engine is on the 2 step around 3000 to 3400 rpm...In fact the converter behind a 410 stroker motor was build in 1983...Turbo Action....buy a good brand name...do not order a 3000 converter...get one made for your engine and car...


    MOPAR 904 500 42RH 42RE TRANSMISSION BILLET REAR SERVO KIT, DODGE, PLYMOUTH AMC | eBay

    some reason not getting a hyper link...but go to ebay and search for 904 rear servo...
    make yourself a shopping list...there are a few places on line you can buy the individual parts....or you can call one of the big names...and pay the big price...
