Abstract
A transmission control system for an automatic transmission for a vehicle causes the automatic transmission to shift according to one of an economy mode shift pattern and a power mode shift pattern. The control system switches the shift pattern from the economy mode shift pattern to the power mode shift pattern when the engine load or the rate of change of the engine load becomes not smaller than a predetermined reference value. The predetermined reference value is changed according to the acceleration of the vehicle body.
