Abstract
An automatic transmission learning control apparatus comprises a memory for storing parameters in memory locations specified for respective gear shift operation modes. A physical quantity related to a gear shift operation made in the automatic transmission is measured. The parameter stored in the memory location specified by the sensed gear shift operation mode is updated in a direction to bring the physical quantity into agreement with a target value. The parameter to be updated is limited between upper and lower limits set for each of the gear shift operation modes. The parameter stored in the memory location specified by the sensed gear shift operation mode is used to control the gear shift operation.
