OD off for this?

I've just moved to Pittsburgh, and the roads here are nothing but very steep inclines, serpentines, and hairpin curves! I've been turning off over-drive when I'm in the steep areas, thinking that will be better for the transmission. Does this sound like a good idea, or am I worrying about nothing?

If you were towing I might say it's a good idea. However, just normal driving I'd say take advantage of the OD as it'll automatically shift and you'll see better fuel economy.

Thumbs up

Use OD off if you are climbing and want the torque converter to lock up in 3rd gear which would make it run cooler and thus better.

It's also a good idea to use OD off (or even third/ second gear depending on transmission) on longer/ steeper descends, gives you more compression braking and saves your brakes/ prevents them from overheating.
