Just how interchangeable is the 360's Manual and F1 Gearbox?

    Hi everyone,

    I'm considering all options after my diff failed in my 360.

    I've been offered a replacement box from a manual 360, mine is an F1. I know they are identical internally but what would I need to make it work with my car? Can I simply change bits over from my F1 box onto the manual box or is there more to it than that?

    Thanks everyone

    The two boxes are the same- you can see this from the parts diagrams as there is no "suitable for GD"/"not suitable for GD" comments against any of the parts.

    The other benefit of this is you can sell off a few of the manual parts from the new 'box... that is unless you don't fancy doing a manual swap? ;)

    Thanks!

    The only thing I've heard that is different is that the studs where the manual gearbox mechanism connect to are too short for the F1 actuator to bolt on to. Can anyone confirm this and whether they can be easily removed and swapped?

    That's correct. Studs for F1 and bolts for manual. They can be swapped.

    Use RTV on the actuator. No gasket.

    If it not too difficult to accomplish— I would perform a visual on the gears to be sure you are not buying a trouble trans.

    might be worth the trouble.
