Pressure Differential Valve Test
1. With the engine stopped, move the transmission selector lever to any position except NEUTRAL.2. Engage the brakes and hold them.3. Start the engine and run it at HIGH IDLE (2400 RPM).4. The direction clutch pressure (P2) must be 0.0 kPa (0.0 psi).5. The speed clutch pressure (P1) must be 2600 105 kPa (377 15 psi).6. The direction clutch pressure (P2) must remain at 0.0 kPa (0.0 psi).7. Move the transmission selector lever to NEUTRAL and then to THIRD SPEED FORWARD or REVERSE.8. The direction clutch pressure (P2) must now be 380 55 kPa (55 8 psi) less than speed clutch pressure (P1).D4C
