Yup, even the Auto 6 speed tranny was designed with snow plowing in mind 68RFE Service Interval and Filter Part Numbers

The 68RE in our trucks was designed with snowplowing in mind from the beginning by Chrysler engineers who engineered the 68rfe without any bands which eliminates breakage issues from the past. The input shaft, UD shaft, OD shaft, output shaft, UD clutch, OD clutch, 2C clutch, overrunning clutch, and the entire planetary geartrain is larger to handle much higher torque numbers. Transmission fluid pump capacity is increased to improve fluid flow through cooler and reduce overall transmission heat. Also, the 68 has a significantly higher reverse gear ratio compared to its predecessor, which reduces heat generation during plowing
