I had to do some construction at the local chevy dealers today and while I was there I thought I would drive one to see what they were like. i'st one was a 1 ton w/6speed. Trans was zero real klunky, coach work left a lot to be desired. Second one had a Allison 5 speed. VERY NICE. I am not a big fan of autos but if Mopar doesn't come out with one of them for out trucks somebody should lose their job FOR SURE. Best trans going by a LOOOONG shot $2200+ extra though.
