The ECM compares the frequency from the speed sensor (HZ) to the number of pulses per revolution in order to determine the speed of the rotating components. The ECM uses the input from the speed sensors in order to regulate transmission shifts.The CX35-P800 transmission has eight forward gears. The ECM will engage the desired gear and speed depending on the gear selected by the operator and transmission ECM programming, which is dependent on operating mode, load factors, output speed of the torque converter and output speed of the transmission. The torque converter will be in torque converter drive for a short time during transmission shifts. This provides smoother engagement of the transmission clutches.The torque converter hydraulic system uses oil that is also common with the transmission hydraulic system. These systems use the same section of the transmission case. Some of the components in the torque converter hydraulic system include a torque converter inlet relief valve, a torque converter outlet relief valve, a gear pump, and a torque converter lockup clutch. Pressurized oil that will engage the lockup clutch comes from the gear pump. Oil flows from the gear pump, through
