    Howdy, just wondering if anyone has ever used a Jet performance power shift on their truck or known anyone who has. I'm seriously considering buying one but i'm having trouble finding reviews on it. I'm really not looking for a true shift kit but something to firm up my shifts and extend the life on the ole 4L60E.
