The transmission seal and the mechatronic connector seals where replaced and everything put back together. Took 2 1/2 , 6 hour days (15 hours) to complete. Slow but meticulous.

After a lot of research on the Web and NewTIS, I came up with a plan. Remove the transmission cross member to get enough space to access the electrical connector and seal. Sounds easy, but it is a bear of a job. So far I've removed: - Front reinforcement panel to gain access for the...

The original BMW lollipop bushings are oil filled. They get a hole and leak the oil out. Easy way to check them is to put a breaker bar on a front wheel bolt and feel the bushing. Stress the wheel in the 3 to 9 o'clock locations and see if there is too much movement at the bushing. There...
