What's up with low gear?

constantly and routinely downshifting in an automatic is a BAD idea, unless you’re driving something like an Audi or Porsche with tiptronic (a dual-purpose automatic with the ability to shift as well), or a similar device from another brand (BMW has them as well). If you do it with a conventional automatic, you’ll wear your clutch our sooner than normal.

Automatic transmissions have a clutch? :eek:

**I was specifically referring to the low/high gearing option that most Jeeps/4X4s have. A Suzuki Samurai will have a simple stick for it (much like a manual gear lever), and a fancy 4X4 like a Range Rover has an electronic switch for it (I think). In any case, it basically cuts the ratios of all gears in half. Or doubles them, whatever. You get the idea.

Yeah, that’s the transfer case low range that’s already been explained. My Jeep had a vacuum-operated shifter (with a switch on the dash) for it.

Yep–Like Gunslinger said…actually a few different sets of clutches and bands…difference is…you don’t engage or disengage these clutches with your foot…the tranny does it for you.
