Got mine from BMW dealership. Wasnt silly money and you know you got the right kit. If you havent done it before, put a drip tray underneath - there's a lot of ATF above the filter just waiting to drop on your head And if its a ZF box you will need a male torx to undo the bolts that hold the filter in. IIRC there are 3. Wont bore you with the filling procedure as this has been gone into ad nauseum.Originally Posted by semiretired
