Default 2006 and newer

Require Dex VI, I use the AMSOIL. No problems, actually shift's smoother. The Dex VI gells at -20 and colder

I too use Amsoil and it does a great job. Like others have said smoother shifts and a quality oil for the temps that mine indures in the deserts towing my toybox each summer.
