Another saga with the X5 (06 4.4i). Every time I get something fixed, another thing pops up! I just fixed my drivers side door handle carrier, New front regulator clips from regulatorfix.com and new BMW black clips. Got them fixed and now I can open my driver's side door again, my windows roll up smooth as silk, and they don't rattle when I close the door or pop when I am rolling the window up or down. I feel happy! I love the X5 again!!! Then she gives me another swift kick in the manhood.

I have been hearing a little more noise than usual from my transmission, so I decided to do a transmission service.

I drained the fluid, installed a new sealing sleeve (was leaking slightly), new filter, and refilled with ZF lifeguard 6. Since then, the car has operated much more smoothly. YAY! Drives smoother, no more lurching at idle! X5 says, "Hey there, not so fast... Open your legs. Another swift kick is headed your way!"

Now I have noticed that I have oil leaking out of the bellhousing inspection ports and have realized that I will need to pull the transmission to replace the transmission input shaft seal. Can anyone please confirm this part number for me? Is it 24-31-7-519-352? Picture borrowed from Rockit....


I am planning on getting this completed over the next few weeks. I also plan on doing the rear main seal and engine coolant cover on the back of the engine. Another pic for clarification of rear main seal (P/N 11-14-7-512-101)
and Engine coolant cover (P/N 11-14-7-504-376)


I will also be ordering new flywheel bolts and a few extra exhaust studs in case I break one or two during the removal.


I plan on taking some pictures during the process and making a how-to for the transmission removal and seal replacements. What are other seals/parts that I should replace at the same time? Transfer case seals?

Any help would be appreciated! I just want to make sure I have everything on hand to try and prevent any unnecessary down time and I need clarification on the input shaft seal part number.

Thanks in advance!
