Abstract

A control system/method to minimize unwanted multiple upshifts in an automated mechanical transmission system (12). After a full-throttle upshift (54A), the engine speeds at which upshifts are commanded are increased from a default value (54) to a modified value (72) until the occurrence of a reset event.
