Abstract
An improved control for an automatic transmission, preferably an automatic mechanical transmission (10), is provided. The improved control includes an operator selectable mode of operation (D.sub.1) for off-road and other higher resistance vehicle operating conditions. In the off-road mode of operation, the central processing unit (30) will generate upshift commands in accordance with an upshift shift point profile (OHU) such that, assuming constant output shaft speed and throttle position, the engine (12) output power following an upshift will be at least as great as the engine output power prior to the upshift.
