id suggest only using oem fluids. with the diff it doesnt have a drain plug so youd have to suck out the old and fill it. the transfer case is a drain and fill with the special oem fluid. the trans is a and top off till it comes out once again wtih the special oem fluid...front diff is drain and fill(though ive never really touched a front diff on an 3 series before)
