|  2005 GMC Sierra shift kit 
			
			I've got an 05 GMC Sierra 1500 4wd with an autotrac transfer case and I believe a 4L60e trans. I've owned it since new. I have 91000 miles on it now. I changed the trans fluid at 50k and 75k, according to GM's guidelines. I've been using a hyper tech programmer since 06. I've been thinking of putting a shift kit in it but I'm not sure since I've got some miles on it. Any opinions?
