I'm noting some threads here that give me some pause concerning my choice of the Aisin transmission. I mainly bought our 2017 3500 dully with the Aisin transmission for pulling a 17,000# 5r but clearly had planned on using it also for small tasks around town (town being 55 mile north of Houston). Think 20 miles round trip to get ice cream. Is it bad for my Aisin to make short trips not loaded?
