yeah unplugged it, mailed it back, truck drives great now

are you guys happy with the Range AFM disabler? I was not. i tried it for 2 days and it caused my 2018 5.3 to down shift hard when slowing down and driving around town this drove me crazy would clunk hard on every down shift , as soon as i unplugged the Range device went back to butter smooth shifting. so i contacted Range and they told me it's known that some trucks have this problem and they would not offer me a return label, I paid $12 to shipped back insured and it seems they are dragggin arse on refunding my paypal anyone else have any problems with this
