PS (Sorry about rousing the rabble on the transmissions, I was just trying to get straightened out. I was thinking that I was planning on spending big money on something that you were saying would devalue my truck. What I learned is there are plenty of guys on both sides of that one, so if I want a stick, somebody would probably buy it, should I have to sell it.)
