Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shiftt o a lower gear when you go
down a steep or long hill.
[quote]A CAUTION:
If you don’t shift down, your brakes could
get so hot that they wouldn’t work well. You
would then have poor braking or even none going
down a hill. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope

NEVER ride the brakes going down a hill! Brakes will fade and you wont like the end results if you see a curve..... wind up needing to use a run-a-way truck ramp and some toilet paper

It'* really more on the engine then anything. You're just running at Higher RPMs and closed throttle, that'* why j00 slow down.

If you are on a steep hill its ok to drop to a lower gear to allow for some engine braking.... I have done this many times throught the Hills and mountains of Virginia and West Virginia.... I still have to use the brakes here and there, trying to stay at 60mph or so going downhill in 2nd gear....<--- this is supposed to be hard on the trans for prolonged periods tho, Might be more of a heat related issue than anything... I'd say if you need to go slow, and you are at 30 in 1st you'll be ok if its for a short time.... Should be 4000 Rpms or so for you if memory serves( if that ) And I think redline would be 42mph? And being a 94 model the tranny should shift to second if the revs get too high, thats with the selector in 1st...

Good Luck

Almost forgot.... 139,200 miles and counting on the original( Abused ) 4T60-E here
