Didn't know there was another case besides the 3.0 and 3.5 (trannies aside). I would think the FSM would tell how to determine. Trouble is no one here is likely to have an FSM that new. The 95 I have is the newest one I've ever heard of anyone having. I'd maybe try calling the dealer with your VIN. Spare yourself the agony of mentioning the 2.85s though as the dealer will be clueless to that kind of drabble.

Also, I believe there are next to no 2.85s left so if you want them, better move quick. I think the last I heard was one set of AT gears left.
