Here is great link to powertrain information. If you click on the links in the table you can bring up interesting info like a dyno sheet. On another note, a 6 speed conversion is available for the 5 speed, it is an easy install, but costs around $4,000. list. http://media.gm.com/us/powertrain/en...08/08truck.htm

 

$4,000.00 should be stock by 2010-11 when they redue the powertrains.

 

Yeah, a bit pricey to mod yourself. Also not sure if it affects the GM LSD or you need to modify that also. Anyway, here it is http://www.autotech.com/quaife/gears/GMF35.htm
