So far Ive read a few post that say to use this when pulling a trailer up an incline but I have no idea why or how. Is it really necessary? How do I set everything up......


Reason im asking is because this is the first trip with the truck to Pismo Beach towing the sandrail and 4 quads.........


Thanks..........

leave it on defuel all locked shifts.......the other settings are for built trannys only........tow on 2 or maybe 3 watch your guages and your tranny temp..use tow haul....Have a safe trip
