ABSTRACT:
An apparatus for controlling an automatic gear transmission and for modifying an optimum gear position based on the engine output and the running resistance for the optimum gear position. If the optimum gear position is a shift-up from the present gear position, the shift-up to the optimum gear position is inhibited when the running resistance is larger than the engine output. If the optimum gear position is the present gear position, the gear transmission is shifted down when the running resistance is larger than the engine output for the present gear position.
