REOF10E/JF017E CVT Valve Body
One of the solenoids on the valve body is called the Lock-Up Select Solenoid (#4 in Figures 2 and 3: two different style valve bodies are shown — Nissan/Mitsubishi and Dodge/Jeep). This solenoid controls the positioning of the Select “Switching” Valve in the valve body (#4 in Figure 4). By doing so, this solenoid controls two different functions. During drive and reverse engagement, this solenoid will place the “switching” valve in a position where it will direct pressure to the Select “Control” Valve (#5 in Figure 4). This “control” valve will reduce line pressure going to the Forward Clutch or Reverse Clutch for a smooth gear engagement. The Lock-up Select Solenoid can then position the “switching” valve where pressure is directed to the Torque Converter Lock-up Control Valve (#3 in Figure 4) for torque converter clutch apply control.
