WOW! Just had ALL my fluids changes two days ago. Based upon Many post I saw here I decided to go with Mobil 1 (AFT, Gear Lube, Additive, the whole works.) Did a full tranny flush...you name it. (Boy, I wish I was a mechanic) I went to a lube shop that specialized in Mobil 1 here in San Diego and after several hours the final damage was $455 big bucks. But the VX runs much smooooother. Thanks to EVERYBODY who had something to say about the matter. Every commit helps. Well that's my 2 cents!;eekr;
