1. A method for controlling an automatic transmission comprising the steps of:
- obtaining positioning data using a global positioning satellite (GPS);
monitoring the automatic transmission to obtain transmission data;
automatically learning whether performance of the automatic transmission is improvable utilizing the positioning data and the transmission data;
wherein the learning step determines that the performance of the automatic transmission is improvable when a predetermined load on the automatic transmission system increases by a particular amount within a particular time;
automatically adjusting a shift threshold for the automatic transmission for the positioning data if the learning step determines that the performance of the automatic transmission is improvable and if the positioning data can be obtained using the GPS, and setting the shift threshold to a preset shift threshold if the positioning data cannot be obtained using the GPS.
