Ok, so how about a few more lessons in driving down big hills, with ONLY the JAKE brake and transmission to control your speed?

I don't have a transmission retarder to help me.

At the top of the hill going say 35mph, do you downshift into 2 or 3rd and maximize the Jake brake to cruise slowly down the big hill? And will that be enough to maintain a slow speed without over reving your rpm's?
