It was pretty windy and raining that day. The next day we got closer to 7.5. I have seen a few of you mention different gears. Should we be pulling in something other than automatic? I think I might be confused. I know you can take it out of automatic, is that what we should do and put it in a different gear? If so, what gear do you recommend? Sorry if that is a silly question! Thanks for all the help!
If your not in rolling hill country or stop and go traffic, with a 7500 lb trailer behind a 6.0 GM 2500 take it out of tow/haul. Don't use the tow/haul on an interstate or other 4 lane highway.
Use tow haul, tow haul keeps the line pressures up. I called a transmission shop before I ever towed with mine. Besides line pressures, up-shifts are delayed.
I have found that my 6.0 HD with 3.72 likes 55. I'm lazy and use the cruise, at this speed the RPM's stay down more. I get about 10mpg towing about 6,000 lbs.
