Thanks. I really like it so far. (Especially not having to punch the throttle hard to kick down a gear and then have it keep trying to constantly get back into overdrive while I'm still going up the hill, making me slow down again, like my previous truck.) I might go Puro then. It will be a while before it needs changed, but I thought I'd get some input now.
As far as the owner's manual says, yeah, guys, I know all about owner's manuals and the MM Act, just trying to get some useful suggestions. Thank's for posting though.
