[Shop-talk] Automatic Transmission Question

[Bill Rabel]

A crucial time to use downshifting is descending a mountain pass using cruise control. Some cruise conrols will apply the brakes to keep the speed constant. 

I once had an Audi in which the brakes were drastically effected by overheating. Downshifting was the cure.

Think the shock-loading on the trans and drivetrain parts shifting in and out of gear at stop lights is harder on things than just leaving it in gear, assuming you're not doing it for half an hour or otherwise in a situation (using torque-converter slip to hold you in position on a hill) that would overheat the thing.
