someone told me that you should not use the "OD" position for in town driving, that you should use the "D" position instead. is this correct, or is either one acceptable? I have been using the "OD" position for a long time without issue
I've never had much experience with any OD tranny shifting or hunting for gears. The manual makes it pretty clear that you should never tow anything when in OD, and I take that a small step further, I turned off OD when hauling anything more than a couple of passangers.
I have yet to come on a time when I needed to pull it out of OD. I've never towed with the Burb yet, but if I did, I'd pull it into drive then, but around Slidell, I run in OD and it never seems to hunt for gears while in traffic.
Well, it´s true, od off kill mpg specially at town. The system "OD" consist in "metaforically" order to on board computer to change the shifts (or gears, i don´t know the difference) quickly to arrive a "D" position as soon as possible. Homever the transmission will do an excesive use a long of life and it´s probably to fault or bad fuction. In resume, for my experience and friends with gm trucks recommend me that i must to use at town the truck with od off.
OD was builded with the mission to grow up the mpg in usa trucks.
Well, is my inexperienced opinion. I hope to help somebody.
