Our own version of the long NLA BMW transmission tool 6039. However we have added our own twist on this tool and made it applicable to more than one transmission flange, making it great for 2002 owners. One side features a 3-bolt flange tool and the other a 4-bolt tool. If you vehicle is equipped with flex disc part #26111106113 or #26111225624 this tool will work on your transmission. It is used to hold the flange in place as you torque the output flange nut.
