Engine/ATX brake?

[Sean L]

Also wondering if it's the tires... maybe they can produce that much drag

You got me... I'm afraid it will still be some time before I can test drive a 3.0 or a Willy's.

The automatic tranny (tyranny??) will either hold the current gear or downshift if you are braking while going down hill. I live in a vey hilly/mountainous area and mine does a very good job of not picking up speed as I go downhill.

It's not braking... its coasting as in not pressing either the gas or the brakes... it slows down like the military vehicles do... like a trans brake.

Normally it's considered a good thing because it saves your brakes. Most automatic transmissions don't provide much compression braking.

You could always just put the trans in Neutral when going down a long hill and it will coast until you put it back in Drive.

I have heard comments the other way around.. do not constantly use your automatic transmission to engine brake... you will cause premature transmission wear.. on the other hand, brake pads are cheap...

Grammar/spelling police everywhere! If that's not tyranny then I don't know what is!

Too funny.

This reminds me, one of the forums I was on a long time ago, someone posted in the general section a desire to discuss time and clocks.

Unfortunately he left out the “L” in the word and the thread derailed from there.

Ehhhh, partially true. Compression braking alone will not cause any additional wear. The only thing that would cause additional wear is downshifting while going down a hill. Downshifting (manual or auto) will cause friction surfaces (bands and clutches) to engage/disengage which will obviously result in wear on those surfaces, but you would need to do it A LOT to see premature wear.

On the other hand, riding your brakes on a long grade with no compression braking assistance can result in brakes overheating and becoming less effective or failing all together. Not so much of an issue in a light weight Jeep, but still something to consider.
