Adaptive Learning

Adaptive Learning:

The TCM programming allows for adjustments in line pressure based on the changing characteristics of the transmission components as sensed from the various TCM inputs. This process is called "Adaptive Learning" and is used to ensure consistent shift patterns and to increase transmission durability. As transmission "apply" components wear and the time required to apply a clutch or band increases, the TCM adjusts line pressure to maintain the originally calibrated shift timing. Line pressure adjustment is accomplished through control of the torque signal fluid pressure, which in turn is controlled by the force motor.
