Mike, not sure who you are addressing your remarks to. For me, there is no 'hunting' or continuous shifting. The transmission will eventually drop down out of 6th gear if the grade is steep enough to warrant it. It will usually stay there until the grade has been cleared. If there is a signifcant grade or series of grades it is a simple matter of enabling tow/haul mode which keeps the transmission out of 6th gear. Speed retardation on the downgrade is greatly enhanced in this mode as well. Engine and transmission temps are nominal. Transmission temperature monitoring is a stock item and reported through the Driver Information Center. I believe this method is optimum for my setup and the speed I drive. Staying low in the power band saves fuel at the same time the engine is operating near its peak torque. The truck is responsive and I am satisfied with the fuel mileage.
