NOTE:
o Clean all parts thoroughly in solvent or carburetor cleaner, and dry them with com-
pressed air. Blow out all passages.
. Replace the valve body as an assembly if any parts are worn or damaged.
. Checkall valvesforfree movement. lf anyfail toslidefreely, see Valve Body Repair on page l4-192.
'1. Hold the regulator spring cap in place while removing the stop bolt. The regulator spring cap is spring loaded Once
the stop bolt is removed, release the spring cap slowly so it does not pop out.
2. Reassembly is the reverse order of disassembly.
NOTE:
. Coat all parts with ATF during reassembly.
. Align the hole in the regulator spring cap with the hole in the valve body, thenpress the spring cap into the valve

Cooler Flushing
@@ To prevent in;ury to face and eyos, atwayswear safety glasses ot a face shield when using thetlansmission flusher.
This procedure should be performed before reinstallingthe transmission.
2.
LCheck equipment for wear and cracks before using.Replace any worn or cracked components.
Using the measuring cup. fill the tank with 21 ounces{approximately 213 lull) ol biodegradable flushingfluid (J35944 - 20). Do not substitute with any otherfluid. Follow the handling procedure on the fluidcontaaner.
Secure the flusher filler cap, and pressurize theflusher with compressed air to 550 - 829 kpa (5.6 _
8.45 kgf/cm,, 80 - 120psi). The air line should beequipped with a water trap to ensure a dry air sys-tem.
Hang the flusher under the vehicle.
Attach the flusher discharge hose to the return lineof the transmission cooler using a clamp.
Connect the drain hose to the inlet line on the trans-mission cooler using a clamp.
IMPORTANT:
Securely clamp the opposite end ofthe drain hose to abucket or floor drain.

Turn on the water valve for 1O seconds. lf waterdoes not flow through the cooler, it is completelyplugged, cannot be flushed, and must be replaced.
Depress the trigger to mix the flushing fluid into thewater flow. Use the wire clip to hold the trigger down.
While flushing with the water and flushing fluid fortwo minutes, turn the air valve on for five secondsevery 15 - 20 seconds to create a surging action.AIR PRESSURE: MAX 845 kpa (8.45 kgf/cmr, t20 psi)
Turn the water valve off. Release the trigger, thenreverse the hoses to the cooler so you can flush inthe opposite direction. Repeat steps 8 through 10.
Release the trigger, and rinse the cooler with wate.for one minute.
Turn the water valve off, and the water supply off.
Turn the air valve on for two minutes, or until nomoisture is visible leaving the drain hose. Residualmoisture in the cooler or lines can damage thetransmission.
Remove the flusher from the cooler line. Attach thedrain hose to a container.
Install the transmission, and leave the drain hoseattached to the cooler line.

Description
Hydraulic Flow
Forward Start and Acceleration l4WD)During a forward start and forward acceleration, the dual pump system can engage four wheel drive.lf the front wheels spin faster than the rear wheels, the front oil pump spins faster than the rear oil pump. The front pump
draws fluid through check valve B and discharges it. Some of the discharged fluid is drawn in the by the rear oil pump.The remaining fluid will pass through check valve E into the clutch piston. There, hydraulic pressure is regulated by twoorifices.
The regulated hydraulic pressure at the clutch piston pushes the plates and discs of the clutch together to form a connec-tion. The engaged clutch then passes driving force from the transfer assembly to the rear wheels, producing 4WD.
oRrFtcEsFRONT OIL PUMPREAR OIL PUMP
Forward Driving at Constant Speed lzWD)When driving forward at a constant speed (cruising), the dual pump system functions in two wheel drive mode.The rotation speed of the front and rear wheels is the same, so the speed of the front and rear pumps is also the same.Fluid discharged by the front oil pump is drawn in by the rear oil pump and is circulated through the system. Becausethere is no pressure built up at the clutch piston, the clutch does not engage, and the vehicle remains in 2WD (front wheeldrive).
