E position
Reverse Inhibitor Conirol
lf the E position is selected while the veiicle is moving forward at speeds over 6 mph (10 km/h), the inhibitor solenoiddoesn't turn off by means of the TcM or PCM Reverse inhibitor pressure (Rl) is not applied to the reverse inhibitor valveas the reverse inhibitor solenoid turns on. The reverse inhibitor valve is kept on the right side, and covers the pon ro sropreverse brake pressure {RVS} to the reverse brake from the manual valve. Reverse brike pressure (RVs) i; not appried tothe reverse brake, and power is not transmitted to the reverse direction.

Description
Hydraulic Flow (cont'd)
lll position, when th€ electronic control system is fauhy.
when the electronic control svstem (linear solenoids and sensors) is faulty, the transmission uses the pitot pipe pressure(PP) to 311o- rh" u"hicle to drive.
when all linear solenoids and sensors are off because of a faulty electronrc control system, clutch reducing pressure (cR)flows to the start clutch control valve, the manual valve, the PH-PL control valve, and the shift control valve. clutch reduc-ing pressure (cR) becomes shift varve pressure (sV) at the shift contror varve, and shift varve pressure {sv) is appried tothe left end of the shift valve and the right end of the shift inhibitor valve. The shift valve moves to the right side. anduncovers the pon that leads high pressure (PH) to the drive pulley and uncovers the po.t tlr"t r""1" ro,,"-pressure (pL) tothe driven pulley At this time, the pulley ratio is high, The shift inhibitor valve moves to the left side, and uncovers theport that leads shift inhibitor pressure (Sll to the pitot lubrication pipe and the pitot regulator valve. tne prtot lubricationpipe discharges fluid inside of the pitot flange, and discharged fluid enters into the pitot pipe and it is applied to the leftend of the pitot regulator valve. The pitot regulator valve moves lo the right side, and uncovers the port that leads pitotregulator pressure (PR) to the shift inhibitor valve. Pitot regulator pressure {pR) becomes start clutch pressure {sc1 at theshift inhibitor valve, and is applied to the stan clutch. The stan clutch rs engaged. The forward clutch pressure (FWD) isapplied to the forward crutch, and the forward crutch is engaged. This alows the vehicre to drive.

Description
Park Mechanism
The park mechanism locks the transmission by engaging the park pawl with the park gear which is integral with the sec-ondary drive gear' The secondary drive gear engages with the secondary driven gear which engages wit-h the final drivengear.
shifting to E position causes the park cone (installed at the end of the park rod) to press the park pawl onto the park gear.Even if the end of the park pawl rides on the top of the park gear teeth, slight movement of the vehicle will cause the parkpawl and the park gear to mesh with each other completely because the park cone receives the tension from the park rodspring The park pawl receives the tension (which acts to separate the park pawl from the park gear) from the park pawlspring.
