You will need a pressure tap because they are not on the transmission, just plugs. you can remove one from the hyd pump if you don't have one.
You will need to remove the access plate in the floor.
(A) Pressure tap for pump pressure. (B) Pressure tap location for lube pressure. (C) Pressure tap location for clutch 1 pressure. (D) Pressure tap location for the clutch 2 pressure. (E) Pressure tap location for the forward low pressure. (F) Pressure tap location for forward high pressure. (G) Pressure tap location for clutch 3 pressure. (H) Pressure tap location for the all-wheel drive clutch pressure. (J) Pressure tap location for the reverse clutch pressure.
1. At pressure tap (A), use a coupler and connect a pressure gauge [4000 kPa (600 psi)] to the nipple.
2. Place the direction conrtol lever in the NEUTRAL position.
3. With the parking brake engaged, start and run the engine at LOW IDLE rpm.
4. Shift the direction control lever into the FORWARD position and with the speed shift lever in NEUTRAL, run the engine at HIGH IDLE rpm. The pressure on the gauge must be 1450 ± 100 kPa (210 ± 15 psi).
5. When this test is complete, reduce engine speed
3. At pressure tap (F), (E), (C), (D), (G) AND (J) connect a pressure gauge [4000 kPa (600 psi)] to the hose group.
4. At pressure tap (B) connect a pressure gauge [400 kPa (60 psi)] to the hose group.
5. Start and run the engine at LOW IDLE speed.
6. With the transmission gear shift lever in NEUTRAL, shift the direction control lever to 1st speed FORWARD. The pressure on the forward low clutch gauge must be 1325 ± 225 kPa (190 ± 30 psi). The pressure on the clutch 1 gauge must be 1375 ± 225 kPa (200 ± 30 psi). The lubrication gauge must be 50 ± 25 kPa (10 ± 5 psi).
7. Shift the direction control lever to 2nd speed forward. The pressure on the forward high clutch must be 1325 ± 225 kPa (205 ± 30 psi). The pressure on the clutch 1 gauge must be 1375 ± 225 kPa (200 ± 30 psi).
8. Shift the direction control lever to 3rd speed forward. The pressure on the forward low clutch must be 1325 ± 225 kPa (205 ± 30 psi). The pressure on the clutch 2 gauge must be 1475 ± 225 kPa (215 ± 30 psi).
9. Now shift the direction control lever to 3rd speed REVERSE. The reverse clutch pressure must be 1325 ± 225 kPa (190 ± 30 psi). The pressure on the clutch 3 gauge must be 1475 ± 225 kPa (215 ± 30 psi).
