Transmission question

set the cruise the jake and roll with it. The I shifts do really well.

 

Have never smoked my brakes coming down a 6° mountain pass 12 speed auto.Get to the gear I want usually 12th gear and jake brake 3 clicks down.May have to do a "stab brake" for a few seconds if it tries to "run away on me.If it's slick (winter time) get to the gear I want and lock that gear into (manual mode) sometimes 35 to 45 mph,No jake and 9th or 10th manual (locked in).If it's "Chains Required" it's 7th gear 25 to 30 mph.Have seen some drivers hotrodding lay it over. Mountains in the winter can be "unpredictable" all of the sudden.If you use a little restraint when you start down the hill there shouldn't be any reason to "Smoke tires.JMO

 

Downshift before the descent. Like just drop 1 gear down and engage engine braking. It should hold and a few brakes stab to keep it at speed.

An automatic can downshift and upshift by human input. I drive an automatic and on a daily I switch it to manual for gearing up faster on a dead stop, going thru a curb, or steep descent.

 

Autos suck. They suck even worse in the mountains. My work day is 1 hour longer when I get stuck with an Auto.

 

I hear ya, W.H.O. except our auto's do Not upshift or downshift by human input.Volvos that is.No clutch at all,much like a car.If you take off in manual it'll just run up rpms and never shift.Our "Manual feature" is only for holding the gear you desire.I know it's Weird!Any way +1 I agree with everything else in your post.

 

EDIT,yes our autos shift up &down but only in D auto mode.
