    A little help. I was hearing a whinning noise comming from the 41 C6S so I checked the transmission fluid and found out I was a little low. Big question, what is the correct transmission fluid to use? In the book it says S.A.E 90 I would like to confirm this with you guys. Thanks.

    Don't fool around, drain it good, like overnight, then fill with 80-140, I use Castrol, and if it Still whines, you have a bad bearing. Walt
