    Hello, my friends

    I will rebuild my TorqueFlite 904 for use in a Mopar 318LA and 100HP nitrous + - 400/450 HP
    KIT which it would be better ?? TCI 129000 or Performance Pro Automatic Max Performance PAKT12701 Kits ???

    http://www.summitracing.com/int/parts/pma-pakt12701

    http://www.summitracing.com/int/parts/tci-129000

    I plan to use a torque converter Hughes 3000 stall, what do you think ??

    http://www.summitracing.com/int/parts/hup-27-30/overview/

    With 4.10 gear and Tires 26x10x15.

    My 904 Transmission will survive??

    Thanks

    I'd make sure and use steel planetary gearsets if your using nitrous cause I doubt aluminum ones would last. If it were me I'd check www.bulkpart.com for the rebuild kit. Neither of those kits say they have bushings and a rear sprague roller kit. That's a must have when building a trans IMO. If I remember right Bulkpart has a complete kit that includes all the small parts that aren't included in the kits from summit and the price is around $250

    As for the converter. I've had good luck with Hughes converters but they don't usually stall as high as their rated. You can get a custom built for your car torque converter from PTC for the same price as the Hughes.

    Yup, keep it basic but highly parted with the kit. Nothing fancy needed accept line pressure and nice tight tolerances. Keep that kickdown rod adjusted right!

    the multi spring kit keeps the front clutch pac dish from dragging at high rpm....the big coil spring becomes unwound .....

    I have 5 904s...they all have the spring kit....dont have problems with front clutch pacs...

    Michel, TrailBeast posted this link in a different thread yesterday. I read it last night and it includes a lot of great information.

    http://www.allpar.com/mopar/transmissions/torqueflite-tom-hand.html

    Near the end of the article the author discusses the different shift kits.

    KIT TF-3 be applied to automatic/manual valves body ??? (STOCK) . No, just automatic valve body.
    Will convert (stock) automatic to heavy duty automatic OR full manual , depending which parts you select to use from the TF-3 kit.

    I don't run nitrous . But from what I've learned. You need a anti ballooning plate on the convertor
