Well I am glad that worked out. It is pretty hard to keep that motor below 2200 when that Jake comes on and it downshifts at the same time. I have found it easier on a 8% or greater grade to manually downshift to fourth gear and let the engine keep the speed down with momentary activation of the Jake. In fourth gear I can usually just keep the Jake on in LOW and let it roll. The worse situation is to not be paying attention in cruise control and have it freewheel going down hill then look at the speedometer and see that you are going above 70 mph. Now when you hit the Jake it comes on but no downshift and it does not slow down fast and requies you to hit the service brakes to get it below 68 mph then it will downshift but that engine is going up to 2500 rpm. I never get a CEL for that.
