Usage:
Start By:
a. remove engine and transmission
NOTE: It is not necessary to make a separation of the transmission and engine as shown in the illustrations.
1. Remove cover (1) from the transmission.
2. Remove sleeve (2) from the manifold and transmission case. Remove the O-ring seals from the sleeve.
3. Remove bolts (3) and (4) that hold the transmission hydraulic control valves to the clutch housing.
4. Install tooling (A) as shown and fasten a hoist. Remove transmission hydraulic control valves (5). The weight is 34 kg (75 lb).
NOTE: The following steps are for the installation of the transmission hydraulic control valves.
5. Install tooling (A) and a hoist to the transmission hydraulic control valves. Put transmission hydraulic control valves (5) in position in the transmission, on the clutch housing.
6. Install bolts (3) and (4) that hold the transmission hydraulic control valves to the clutch housing. Tighten the bolts to a torque of 48 ± 4 N·m (35 ± 3 lb ft)
7. Inspect O-ring seals for damage and make a replacement if needed. Install O-ring seals on sleeve (2). Install sleeve (2).
8. Put the gasket in position and install cover (1) on the transmission.
