Torque Reduction Control System
Torque Reduction Control System Flow Chart:
DESCRIPTION The 4F20E automatic transaxle employs electronic control of the powertrain for controlled shift points, line pressure, and self-learning. The communication between the
powertrain control module (PCM) and the transmission control module
(TCM) improves shift feel during quick start and quick acceleration.
