If you have not done this already, it may be a great idea to flush your old transmission and diff fluids. It was definitely time to do it on my S52 Z3M.
Nice. Just did this job on my M roadster last weekend. I also did the fuel filter while I was under there and that thing was NASTY dirty. It was an oem filter so i bet it hadnt been changed since the factory 70k mi ago.
Thanks for pointing that out! It was on the list, but somehow I missed it. I am willing to bet that it has never been replaced on my car either and I'm at 100k.
@@CarGuy1 looking forward to seeing you replace the detents! Mine are going bad too. Same with the clutch line. Apparently switching to a stainless clutch line really changes the feel.
PO had the clutch replaced. It is a bit odd that they didn't do the fluid at the same time. Unfortunately they didn't replace the detents either. Next item on the menu is either the oil pump but and baffle or randy Forbes kit.
75W-140 is for M variable Lock diffs, which first appeared in E46. Prior to this, BMW specified Castrol 75W-90. I ran this for the last 2k miles with no issues at all.
@@CarGuy1 This is incorrect! For all Z3 and Z3M which have LSD, 75W-140 is required! Please do not provide these false information to other BMW drivers, as you/they will crush their diff with the wrong oil.
Great video! Going to be doing the same on my 99 M Roadster. Hopefully I can get the trunk floor reinforced this year too!

I like your videos, have you thought about doing a video on the shifter lever to the transmission seal?? More z3stuff please
Have you done the clutch on this car yet? Do you plan to do a video on the clutch?
