LEARNING CONTROL • Oil pressure control timing is optimally corrected at the time of clutch engagement and disengagement and controlled to bring the speed-change time to the value preset to the TCM and compensate the • When the gear is shifted, the clutch pressure 2 is optimally corrected so that the speed-change time is as near as the target value 1 preset to the TCM and the changes in the engine performance and the changes of the transmission with time can be compensated based on the past speed-change results. • When the clutch is operated to shift the gear, the time of the clutch oil pressure release timing 4 on the disengagement side is optimally corrected so that the changes of the engine rpm 3 is optimum.
• When the battery terminal is disconnected, contents of learning are cleared and resultantly the speed change shock may increase. After the vehicle has traveled, learning is repeated and the shock
