Brought my 2nd gear back! Awesome product. I have a 2006 GMC Sierra 6.0 vortec max with the 4L70E.Truck was shifting from 1-3rd gear totally bypassing 2nd. Suspected slop in the 2-4 band. Installed this kit and 2nd gear is back. Could be back for a week, could be back for years..gives me some time to gather parts for my 4L80E swap.The only negative is that this does not include a servo cover o-ring and you WILL wreck yours during removal so be sure to buy one beforehand.
2nd servo great high performance product
