Dear Tom and Ray:
Debbie
TOM: Gee, Debbie, we often have a lot of trouble deciding which two or three questions we can answer in any given week. But your bribe made it easy this time.
RAY: The answer to your first question is yes. Not only is it OK to put your automatic transmission is a lower gear when decending a steep hill, it's required! You're not "saving the brakes" from wearing out. You're "saving" them from overheating. When brakes get too hot, the brake fluid can boil and the brakes can fail. Not the greatest way to see the southern slope of the Matterhorn, if you know what I mean.
RAY: So putting the car in second, or even first on a very steep hill, uses the compression of the engine to help keep the car's speed down to a managable level, which allows you to use the brakes less often. And even though it makes the engine sound like it's racing, it's the right thing to do.
TOM: The answer to your second question is also yes. An automatic transmission doesn't actually shift into Neutral when you stop. Rather, the "torque converter" just stops transferring power to the wheels, so the engine can keep turning while the car sits still. And that works in any gear--Overdrive, Drive, Second, First, or Reverse.
RAY: So use a lower gear when decending steep hills, stop whenever you need to, and send the Toblerones to my home address, otherwise my brother will jump on them before I have a fighting chance.

RAY: Hey, did you hear that our new pamphlet, "Ten Ways You May Be Ruining Your Car Without Even Knowing It," is a million seller!
TOM: That's not what I said, you knucklehead. I said I had a MILLION of them in the CELLAR!
RAY: Oh. Well, it's still got loads of great information on how to make your car last forever.
