The sticker in the glove box of my Avalanche has 93 codes in 11 rows and the only "G" code is "GT5" which indicates a 4.10 gear ratio... Correct?
Correct! :B
So I may have that more rare Avalanche designed for towing???
Probably has an extra transmission cooler but otherwise no different for towing except the engine will rev quite a bit higher at any given road speed than does mine which is equipped with a 3.42 axle. I always tow in 3rd, depending on how heavy a trailer you end up towing you
might find it possible to tow in Drive.
