Default Re: Down Shifting or Braking

Selecting a gear to assist in speed control on a long grade? Absolutely agree it is advantageous.
Gearing down through the gears while slowing to a stop? Bad idea, hard on the transmission, and brakes are less expensive.
This is true of almost all vehicles, gas or diesel, automatic or manual. (Clutches cost a lot more than brakes).
The exception would be motorcycles, where you have to downshift through all the gears, though it is up to you whether you let the clutch out in each one.

I don't see how downshifting while slowing to a stop is hard on an automatic transmission. The clutches in an automatic tranny are very different than the clutch in a manual tranny. Wet vs dry, huge difference.

The more you use them, the more they slip and wear.
And clutches are often the first part to wear out (Or at least require replacement) in an AT trannie.

One thing I have noticed with my 2016 Sprinter is it does not stop on a dime, like a your basic car sedan. I live in mountaineous Western Colorado, and with the vehicle’s conversion weight, extended braking could easily wear-out the brakes. On long steeper downhills, I need to be a little more aware of braking earlier for tight turns, red lights, or upcoming slower vehicles. The slowing strategy of braking to your desired speed (without riding or pumping the brakes) and then maintaining that speed with the manual shifting seems like good advice. Thanx for everyone’s two cents on this topic.

Use both trans and brakes simultaneously in moderation.
