I finally got my 09 home and running. The truck has 91,000 miles on it and had a new rebuild on the trans right before the motor broke. I've driven it maybe three or four miles and the transmission seems to shift great without tuning it. The tow haul works also. Is there a reason to have to have a program written to change it? I have the programmer just haven't hooked it up to get a down load and send in.
