Hi, I have a 920m with 200 hours. The left side trans has started to leak. It seems to be coming from around the top. Someone said it’s some kind of a cracked plug and I’ve heard this is common on these trans. I can attest to that as the right side did the same and was repaired by the dealer under warranty last year. Now it’s out of warranty and of course the left side now leaks. Has anyone tackled this kind of job themselves? The dealer wants over 800 to do it even though it is a part that is obviously set up to fail. I would appreciate any guidance on how to do this job. Thanks so much!
