Hey guys and Girls , New to the forum and Just got a new 2011 gmc sierra w/t 4x4 with 5.3 with a 6 spd automatic with 3:42 gears , I was wanting to know if i could put in 4:10- 4:11 gears and run somewhat decent at 65mph ??? right now i can go about 80 @ 2100 rpms , But i was also was curious if i have do do anything else with computer or traction control etc when i go to change gears so it runs right with no computer errors popping up ? I would love to see it run about 1,900 to 2,000 rpms with the stock tires i have on it , all help greatly appreciated , thank you in advance ;-)
