Planning on buying a 06 2500qc w/ 6speed tranny.
If i get it i plan on doing a smarty programmer, 5" stacks, gauges, airdog 100/150?? intake. this truck will be my daily driver and will probly tow 8-15000lbs a few times a week, what would be best to upgrade the tranny?

 

South Bend Dual Disc!

3600# Ceramic, IMO. I tried an OFE single and a Street DD (organic 3250#). If I had to do it again, that's what I'd go with.

I guarantee, the mods won't stop with what you've listed...
