PL Regulator Valve Body
The PL regulator valve body contains the PL regulator valve and the PH-PL control valve. which is joined wirh the pH-pL
control linear solenoid. The inhibitor solenoid is bolted on the pL regulator valve body.
. PL Regulator Valve
The PL regulator valve supplies low p.essure (pL) to the pulley to eliminate steel belt slippage.
The PL pressure is controlled by the pH-pL control pressure (HLC).
. PH-PL Control Valve
The PH-PL control valve controls the PL regulator valve according to engine torque. The PH-PL control valve suoolies
PH-PL control pressure (HLC) to the PH control valve to regulate PH pressure higher than pL pressure. The pH-pL con-
trol valve is controlled by the PH-PL control linear solenoid. which is controlled by the TcM or pcM,
. Inhibitor Solenoid
The inhibitor solenoid controls the reverse inhibitor valve by turning on and off. Also, the inhibitor solenoad controls pH
control pressure (PHC) by applying reverse inhibitor pressure (Rl) to the PH control valve. The inhibitor solenoid is con-
trolled by the TCM or Pclvl.
Start Clutch Control Valv€ Body
The start clutch control valve body contains the start clutch control valve. Both are joined to the stan clutch control linear
s o l e n o i d .
. Start Clutch Control Valve
The start clutch control valve controls start clutch engagement according to the throttle opening. The start clutch con,
trol valve is controlled by the stan clutch control linear solenoid, which is controlled bv the TCM o. pCM.
