| s1 | Solenoid Valve S1 |
| s2 | Solenoid Valve S2 |
The normally open solenoid valve is mounted in the transmission valve housing and is used by TCM when activating C2. The pressure to SLC2 is then raised from system pressure to D-pressure. The valve is also used to apply pressure to brake B2 for engine braking in 1st gear.
The control module activates the valve by applying B+ to it. The valve is powered from control module pin 5 in the connector in direct contact with the transmission on the bottom of the control module. The valve is grounded in the valve housing.
