ABSTRACT:
A method/system for controlling downshifting in an automated mechanical transmission system (10) utilized on a vehicle. The anti-hunt logic after an upshift will sense conditions of high throttle demand (THL>85%) and low vehicle acceleration (d/dt(OS)<0) and reduce at least a portion (72) of the direction of last shift anti-hunt offset to the downshift profiles.
