Transmission Pressure Chart
Pressure	Pressure Tap	Governor Control Lever Position
Pressure	Pressure Tap	Low Idle	High Idle	Adjustment
Transmission Lubrication Oil	A	7 kPa (1 psi)	331 ± 41 kPa (48 ± 6 psi)	None
Converter Outlet Pressure	B		415 kPa (60 psi) minimum 550 kPa (80 psi) maximum with the engine speed at 2100 rpm and transmission in NEUTRAL	Add or remove the amount of spacers (28). See the SPACER CHART.
Converter Inlet Pressure P3	C		980 kPa (142) Maximum with cold oil	None
Speed Clutch (P1) (Initial Pressure)	D	550 ± 35 kPa (80 ± 5 psi) with the direction selector in the NEUTRAL position, and the speed selector in the FIRST position. Load piston plug (G) is removed.		Add or remove the amount of spacers (29). See the SPACER CHART.
Speed Clutch (P1)	D	The pressure must be 2206 kPa (320 psi) minimum, with the speed selector in the FIRST position, and the selector lever in a FORWARD position. Load piston plug (G) is installed.	2550 ± 138 kPa (370 ± 20 psi) with the selector lever in any FORWARD speed. Load piston plug (G) is installed.	None
Oil Pump	E	2150 kPa (310 psi)	2760 ± 115 kPa (400 ± 17 psi)	None
Direction Clutch P2	F	379 ± 55 kPa (55 ± 8 psi) less than the speed clutch pressure at tap (D). Load piston plug (G) is installed.	379 ± 55 kPa (55 ± 8 psi) less than the speed clutch pressure at tap (D). Load piston plug (G) is installed.	None
