I bought this dabler for my 2014 gmc sierra with a 5.3l v8. So far it works great! the truck is now shifting smoother because its not having to shift due to afm kivking on or off, and certainly saves wear and dear on the torque converter this way. my gas milage has decreased slightly on the highway as expected, but not ebough to really be an issue(i.e 11.5 liters per 100 kms instead of 10.9 l per 100 km difference), but i've noticed something else. my gas milage in-town has vastly improved. The one thing i will warn you as i found out the hard way a couple nights ago in our -40 cold snap in Alberta, you must unplug this module when it gets down below -30 celcius, or it may wreck the module and kill your battery in the process. luckily after mine warmed up for 24 hours, it is working again.

Installed in my 2013 Chevy Avalanche. Works great. Noticeable improvement in performance. Vehicle often sits for 3 days without use and has no effect on battery. Fantastic product for half the price of the big name module.
