Circuit / System Description
The clutch pressure control?(PC) solenoid?5 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The clutch PC solenoid?5 flows fluid to the 1-2-3-4 clutch when commanded ON and exhausts fluid when commanded OFF. The clutch PC solenoid?5 regulates the transmission fluid pressure to the 1-2-3-4 clutch. Solenoid power is supplied by the TCM through a high side driver?(HSD). The HSD protects the circuits and components that the TCM powers. Should the circuit overload the driver will shutdown. After the overload is removed the HSD reset. The TCM calculates gear ratio based on data from the automatic transmission input speed sensor?(ISS) and the output speed sensor?(OSS). The TCM compares the expected transmission gear ratio to the calculated gear ratio for each commanded gear.
