Solenoid Valve (Upshift, Downshift, or Lockup)
Illustration 1 g01191642
Solenoid Valve (Upshift, Downshift, or Lockup)
The upshift and downshift solenoids are outputs of the ECM. The upshift solenoid connects to the ECM at connector contact J2-3. The downshift solenoid connects to the ECM at connector contact J1-12. The upshift solenoid and the downshift solenoid are used to shift the transmission. When the ECM decides to shift, the corresponding solenoid is activated with +battery voltage until the shift occurs. The upshift solenoid and the downshift solenoid control the flow of oil that turns the rotary actuator. The rotary actuator is in the transmission hydraulic control system. Movement (turning) of the rotary actuator shifts the transmission. The upshift solenoid and the downshift solenoid are located on the transmission hydraulic controls at the top of the transmission.The lockup solenoid is an output of the ECM. The lockup solenoid connects to contact J1-62. The lockup solenoid electrically controls the direct drive function. The ECM activates the lockup solenoid with +battery voltage and the lockup solenoid is deactivated when +battery voltage is not present. The lockup solenoid controls the flow of the oil to the lockup clutch valve. Direct drive is used in the upper transmission speeds. The lockup solenoid is activated when the machine is in direct drive. Torque converter drive is used in the lower transmission speeds. The lockup solenoid is deactivated when the machine is using torque converter drive.The solenoids have a connector with two contacts. The solenoid receives +battery voltage from the ECM through Contact 1. The solenoid receives ground from the ECM through contact 2.The ECM records diagnostic codes that occur with the following solenoids: the upshift solenoid, the downshift solenoid and the lockup solenoids. A diagnostic code with the upshift solenoid is recorded as a CID 0707. A diagnostic code with the downshift solenoid is recorded as a CID 0708. A diagnostic code with the lockup solenoid is recorded as a CID 0709.
