If you have a Dodge the first thing you turn on is the exhaust brake, loaded or empty. This is a must to keep the gunk from building up in your turbo and exhaust. If you don't, you will have problems down the road. Ask any Dodge tech. When driving in town you also want to keep your RPM's up for the same reason. Manually set your tranny to do this and you can also use Tow/Haul to help. When loaded, Tow/Haul should always be on. It will keep your tranny in lower gears longer to get the best power to get you up to speed. If it is not on and the tranny shifts too soon the engine will lug, also bad. On diesels you must keep the RPM's up for both power and clean running. Also per Dodge techs manually lock your tranny in 5th gear. It is not Tow/Haul that will keep your truck hunting gears, but the RPM's in 6th are not high enough to keep power to the rear wheels to keep it in 6th. It is hunting in and out of overdrive which is no good for the tranny. Only shift it into D when it is very level out where it will maintain the speed without shifting. You will see when in 5th on hilly roads the truck will just drone along and only shift when confronted with the steepest of hills. Why? because the RPM's are high enough to maintain the speed. You will also get better fuel mileage too. Also some people think when you shift the truck into 5th gear you have to manually down shift when coming to a stop.....no, you just stop and go, no manually shifting. If you tow in 6th gear and the truck hunts gears it will heat up your tranny=not good. Not sure on other trucks but even on steeper hills keep Tow/Haul on...and you can still use cruise. Using cruise even on steep hills will work with your tranny and exhaust brake to maintain the speed it is set at....Let the truck do the thinking...it can do the job better then any human. Now that is not to say on the really steep hills you may have to step on the brake too...lol lol lol....Too many guys are still of the impression that they want manual trannys cause they think they can shift better....nay, nay, nay says Dodge. The trucks now days do a better job.
