Thread: 901 trans on a 7R case possible?

    901 trans on a 7R case possible?

    Hi,

    I know it sounds strange as people normally want to go the other route.

    I plan to build different engine (more peaky -> +4000 rpm) but will stay below 200hp
    It will be based on based on a 2.4T (7R-case).
    I have a fully rebuild and healthy 901 5 speed transmission. I like the dogleg shift pattern

    So question is if I can mate my 901-transmission to a 7R-case?

    Thanks,
    Bart

    The mounting is the same but you need to change the flywheel....

    Have had this combo in my track car since 1992 and it still works fine. 2.7 L RS style engine dyno'd @about 240 HP at flywheel.

    Yes it worked for me. 901/13 trans to a 7r case. Trans, clutch, flywheel, and starter were all original to the car. No problems at all.
