A method/system for controlling upshifting in an automated mechanical transmission system (10) utilized on a vehicle preferably having an ECU (28) operated friction upshift brake (26). To prevent thermal damage to the upshift brake, a predicted brake temperature (TEMPP) at completion of an aided upshift is determined and compared to an allowable maximum (TEMPMAX). If predicted brake temperature exceeds the maximum (TEMPP > TEMPMAX) using the upshift brake for the upshift is prohibited. <IMAGE> |
