88 325ix what fluid i should use in tranny,transfer case ,front and rear differential

[Slow325i]

I just bought 88 325ix with 200k miles, i going to change fluid in tranny, transfer case ,front and rear differential
I was wandering what kinda fluid and what weight i shoud use
On my 89 325i i find out Redline MTL is way to go (after using some other brands from local autostore)
Should i use Redline in all other ???

YOu might as well, or you might be spending your hard earned cash on a new transfer case, and you KNOW how $$ that is.... They have all the appropriate fluids. You can look them up on bavauto.com
