strange - remember that 4lo is supposed to be for non-paved roads or just straight ahead maneuvers (like pulling froward up a boat ramp) to avoid driveline bind. It will tolerate some light turning just be verrry careful.

is it so bumpy that you are starting and stopping alot? You could be building too much heat, what does your tranny gauge show? if so, try to set a rpm (like 1800) in 4lo, this is enough to keep you moving slowly but not working up as much heat as starting and stopping....
