I bought all of the seals anyway as they were cheap and I want to try and get it all done in one go. I have searche for ages to find a guide to replacing the larger seals but cannot find anything at all. Does anyone have any useful information at all? The Haynes manual is useless in this regard as it simply says to send it to a BMW dealer. I thought that I wouldnt be touching the gears and so won't need to reshot etc.
