No
Troubleshooting complete. Find cause for loss of oil.
No
Troubleshooting complete.
No
Check electrical connections at transmission. Is there power to the clutch solenoids?
Yes Check for broken universal joint or drive shaft and repair as required. Is there still a problem? Yes Check to see if drive shaft turns with transmission directional control lever (FNR) in forward or reverse and rear wheels off the ground. Does the drive shaft turn?
No
Yes
Check pressure and pump flow. See page 22 22.. Is flow in specified range?

Check regulated clutch pressure at Test Port 3 . See page 18 18.. Is the pressure in the specified range?
No
Possible causes include: 1. If pressure remains remains at zero in forward forward,, neutral and reverse the problem could be in the control valve.
Yes Check the transmission. See Section 6007. Repair or replace as required.
2. If pressure is low, low, problem could be in the the control valve. 3. If pressure for for forward forward and reverse reverse are the same, problem could be in the control valve. 4. If pressure for for forward forward and reverse reverse are different, inspect individual clutch circuits. See Section 4007 for repair.
4WD Does Not Work Check for broken universal universal joint or front drive shaft, and repair as required. Is there still a problem?
No
Troubleshooting complete.
No
If the front drive shaft turned with the directional control lever (FNR) in forward or reverse,, the problem is in the front axle. See reverse Section 5006. Repair as required.
No
Check rocker switch connection and fuse panel. See Section 4001.
No
See Section 6007. Repair or replace as required.
Yes Check to see if front drive shaft turns with transmission direction control lever (FNR) in forward forw ard or reverse and the all al l wheels off the ground. Does the ront drive shaft turn? Yes Check electrical connection at 4WD solenoid on the transmission. Is there power to the solenoid? Yes Check 4WD solenoid for proper operation. With no power to the solenoid the 4WD should be engaged. See Section 4001 and check the 4WD solenoid. Is solenoid performing correctly? Yes Inspect the front drive shaft and clutch engagement teeth for damage. See Section 6007. Repair as required.
