Since we are on this subject. What is good fluid for a 95' manual trans? I like using synth stuff but I would rather have some opinions. Also, is there a filter to change with a manual and how do you change it and drain fluid etc etc.

There is no filter to change with the ZF6. There are two plugs, a drain plug and a fill plug. As always, check to make sure you can loosen the fill plug before removing the drain plug! Nothing like draining all the fluid out of your tranny, only to find that you can't get the fill plug out!
Try searching the Tech Tips section for a "how-to" on changing your own fluid...it's not that difficult, you just have to have the right stuff. The other option is having a local shop do it (and you supply the new fluid). Shouldn't take them more than 30minutes, inlcluding raising/lowering the car on the lift.

The BMW stuff is actually motor oil, and you'll have to pick it up at a dealership's parts counter. The guy might give you a funny look, but don't worry, MANY people here use the stuff.

Matter of fact, there used to be a ZF transmissions US website. But you might also like to look at zfdoc.com. May be excessive, but their conclusion is changing the man trans fluid every 12K miles.

Per Chris Petris in his C4 class this summer: "It is OK to use Mobil 1 10W30 in the 6-speed." I found this in my class notes.

I'll have to look for the page number, but I think it was stated in the late 90's section of the book.

Well thanks to another member for listing the GM part number. I went back and got the right stuff. Some people just have no clue.
By the way 2 questions:
1) How do you know your filled?
2) What tool/size is needed?
okay 3
3) Where are the fill/empty bolts?
Yes, I know to check the fill bolt to ensure it comes off before draining.
