all this is very helpful and I did not know some of this yet but not to old to learn what I was really after was on a gentle hill that you can safely roll down 60-62 with pac brake on not having to use any brake but keep the tranny from shifting down maybe iam expecting to much
The only way to have the exhaust brake on and NOT downshift TOWARD (not directly TO) the pre-select gear (the one in your left shift window/only shift window) is to have an Allison dealer program in a higher pre-select gear for the exhaust brake.
While 2nd and 4th are popular pre-select gears, I have mine set to 5th-- personal choice.
BTW, some of the information posted here does NOT apply to your Allison 3000 transmission (such as grade brake).
