Abstract
An electronic control circuit memorizes shift patterns of a 2-range and an L-range in addition to a shift pattern of a D-range. An operation switch changes a shift pattern of the electronic control circuit to any shift pattern among those of the D-range, 2-range and L-range when a manual shift lever is in a D-range position. A lock mechanism prevents the manual shift lever from entering a 2-range position and an L-range position. A lock mechanism is releasable. A hydraulic circuit is set to a third speed mode when the manual shift lever is in the D-range position, the circuit is set to a second speed mode when it is in the 2-range position, and the circuit is set to a first speed mode when it is in the L-range position, respectively, in case where the shift valves are not working.
