Now about why transmission temperatures should be regulated -- excessive heat can warp things like clutch packs, torque converter blades, and the steel belt. Once a steady speed is met, the transmission control module adjusts to the highest gear ratio possible to reduce engine RPM resulting in reduced fuel consumption and emissions. This characteristic takes some time to become accustomed to and may lead you to believe the transmission is slipping or that the engine RPM does not change in direct relation to accelerator input.
