Transmission Pressure    
Pressure     Pressure Tap     Engine RPM     Adjustment    
Pressure at Low Idle Pressure at High Idle    
Transmission Lubrication Oil     (A)         This pressure is
152 kPa (22 psi).     None    
Converter Outlet     (B)         This pressure is
415 kPa (60 psi) minimum. This pressure is
550 kPa (80 psi) maximum. The axle shafts must be installed. The speed selector must be in the THIRD SPEED position. The brakes must be applied and the converter stalled.     Add spacers (2) or remove spacers (2).    
Converter Inlet P3     (C)         This pressure is
980 kPa (142 psi) maximum with cold oil.     None    
Speed Clutch P1 (Initial Pressure)     (D)     The pressure is
550 35 kPa (80 5 psi) when the direction switch is in the NEUTRAL position and the speed selector is in FIRST. Plug (G) for the load piston is removed.         Add spacers (3) or remove spacers (3).    
Speed Clutch P1     (D)     This pressure must be a minimum of
2206 kPa (320 psi) when the direction switch is in FORWARD or in REVERSE and any speed is selected. Plug (G) for the load piston is installed.     This pressure is
2550 140 kPa (370 20 psi) when the direction switch is in FORWARD or in REVERSE and any speed is selected. Plug (G) for the load piston is installed.     None    
Oil Pump     (E)     The pressure is
2150 kPa (310 psi) minimum.     This pressure is
2685 115 kPa (390 17 psi).     None    
Direction Clutch P2     (F)     This pressure is
380 55 kPa (55 8 psi) lower than the speed clutch pressure at pressure tap (D). Plug (G) for the load piston is installed.     This pressure is
380 55 kPa (55 8 psi) lower than the speed clutch pressure at pressure tap (D). Plug (G) for the load piston is installed.     None    Adjustments for the Transmission Pressures
