ABSTRACT:
An electronic gear transmission control apparatus commands an optimum gear position based on a shift schedule map according to a vehicle speed and an accelerator opening. When an upshift over two or more gear positions is commanded on the basis of the shift schedule map, a gear shift to the commanded gear position is restrained, and a gear shift to a gear position which is one gear position higher than the present gear position is effected for a prescribed period of time.
