Volvo Automatics

If it takes more than 3 sec after you take your foot off the brake something is wrong

 

My 1951 Studebaker Champion has a "Hill Holder". Keeps me from rolling backwards as long as the clutch is held down. Engage the clutch and away you go, no need to fiddle with the brakes or slip the clutch.
Option on many cars starting in the 1930's.
Clever little devil can tell when you are on a hill all by itself, no computer needed.

 

What about rollback while in park. I hit the brake in park then got out of the truck and a minute later it was rolling back in into a wall?

 

The company I temporarily work for has disconnect the manual override in all their volvos.

 

Pulling a yellow push button on the dash, usually prevents the truck rolling forward or back.
This solution was tested by many drivers.
It worked all the time.

 

I-Shift is a trans gender.
IT. Not She nor Him.
