Abstract
A method for smoothing skip up-shifts in an automated mechanical transmission system (10) without requiring direct sensing of the rotational speed of the engine (14) is provided. The method involves delaying re-engagement of the master clutch (16) after engagement of a selected transmission ratio (E) during a skip up-shift by a period of time (T) directly proportional to the number (N) of ratios skipped and/or a function of the identity of the newly engaged ratio.
