When the Transmission Control Relay contact points are closed, the solenoid assembly receives electrical power. The TCM can then operate the
solenoids, as determined by its programming. The relay provides power to all four solenoids through a single wire. This means that all the solenoids have
voltage supplied to them whenever the Transmission Control Relay is closed. The solenoids, however, are not energized until the TCM grounds the
solenoid return wire for the solenoid that is needed.
The assembly is mounted to the outside of the transaxle case, under a sound shield protective cover, toward the front of the vehicle. There are two
gaskets that seal the solenoid pack to the steel plate. There are also small solenoid valve filters used to protect the valves from contamination. These
filters are not replaceable. If the valve body and solenoid pack have been heavily contaminated, the solenoid pack should be closely inspected to
determine if it should be replaced. The solenoid pack is not a serviceable unit.
The Solenoid and Pressure Switch Assembly is supplied voltage by the Transmission Control Relay. The assembly consists of four solenoid/valve
assemblies that control hydraulic pressure to four of the five clutches in the transaxle and the torque converter clutch. A unique feature of the
solenoid/valves is that they directly control the application of a clutch. In other electronically controlled transaxles/transmissions, the clutches are
indirectly controlled by the solenoids through normal hydraulic valving. The solenoid assembly also contains pressure switches that feed information to
the TCM.
Vehicle Speed Signal
The vehicle speed signal is sent as a direct input from the TCM to PCM. The output speed sensor signal is sent to the.TCM and used as the vehicle speed
signal. The TCM converts the output speed sensor signal to an 8000 pulse-per-mile signal. The signal is then sent directly to the PCM. The PCM
receives this signal and converts it to a signal that can be used by the Body Control Module (BCM), which controls the instrument cluster. The signal
from the PCM to the BCM is sent over the CCD Bus.
