It takes Dexron/Mercon, but I changed mine over to the Royal Purple equivalent.. I made things way more quiet.. Expensive at $15 a quart, but well worth it.

I used Mobil 1 in mine very recently. Smoothes things out nicely.

Ran 2 trannys with ATF and never will do it again. Both trannys had the blocker rings go out and got stuck in gear.

Was just searching this and ran across a pdf file from ZF. Most of their reccomendations were 75-80wt gear oil. synthetic. They also stated anything over a 80wt oil would cause harder shifting when cold.

Full Synth ATF.

Remember, if you buy cheap oil for your trans, your not helping it any.

The royal purple has good results from what I know.
Just make sure its a full synth.
