0A-2 GENERAL INFORMATION
GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or the frame.
3. Support the vehicle on chassis stands.
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination.
5. Disconnect the grounding cable from the battery before performing service operations.
This will prevent cable damage or burning due to short circuiting.
6. Handle brake fluid and antifreeze solution with great care.
Spilling these liquids on painted surfaces will damage the paint.
7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe
service operations.
8. Always use genuine ISUZU replacement parts.
9. Discard used cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts at disassembly.
Normal function of these parts cannot be guaranteed if they are reused.
10. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation.
11. Keep the disassembled parts neatly in groups. This will facilitate smooth and correct reassembly.
12. Keep fixing nuts and bolts separate. Fixing nuts and bolts vary in hardness and design according to installation position.
13. Clean all parts before inspection or reassembly.
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and obstructions.
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation.
16. Use the recommended liquid gasket to prevent leakage.
17. Carefully observe all nut and bolt torque specifications.
18. W hen removing or replacing parts that require refrigerant to the discharged from the air conditioning system, be sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a,
to promote the aim of the protection of the ozone layer covering the earth.
19. Check and recheck your work. No service operation is complete until you have done this.

Disassembly
1. Clean the oil pump with solvent (plug the discharge
and suction ports to prevent the entry of solvent).
Be careful not to expose the oil seal of the shaft assembly to solvent.
2. Remove the bolt, suction pipe and O-ring.
3. Remove the nut and bracket.
4. Remove the nut, washer and joint.
5. Remove the connector, O-ring, relief valve and spring.
6. Remove the bolt, rear housing and O-ring.
7. Remove the pump cartridge assembly and the side plate from the shaft. Remove two O-rings.
Inspection and Repair
Make all necessary adjustments, repairs, and part
replacements if wear, damage, or other problems are
discovered during inspection.
Rotor
442RS002
Check that the groove in the vane is free from excessive
wear and that the vane slides smoothly. W hen part
replacement becomes necessary, the pump cartridge
should be replaced as a subassembly.
Vane
442RS003
Sliding faces of the vane should be free from wear. (In
particular the curved face at the tip that makes contact
with the cam should be free from wear and distortion).
W hen part replacement becomes necessary, the pump
cartridge should be replaced as a subassembly.
Cam
The inner face of the cam should have a uniform
contact pattern without a sign of step wear. W hen part
replacement becomes necessary, the pump cartridge
should be replaced as a subassembly.
Side Plate
The sliding faces of parts must be free from step wear
(more than 0.01 mm (0.0004 in)), which can be felt by a
finger nail.
Parts with minor scores may be reused after lapping the
face.
Relief Valve
The sliding face of the valve must be free from burrs
and damage. Parts with minor scores may be reused
after smoothing with emery cloth (#800 or finer).
Shaft and Housing Assembly
The bushing fitting face on the shaft must be free from
damage and wear.
O-ring
Be sure to discard used parts, and always use new
parts for installation. Prior to installation, lubricate all
seals and rings with power steering fluid.

Clean and Inspect
Do not use solvents on neoprene seals,
composition faced clutch plates or thrust
washers as damage to parts may occur.
After complete disassembly of a component, wash all metal parts in a clean solvent and dry with compressed air. Blow
oil passages out and check to make sure they are not obstructed, small passages should be checked with tag wire. All
parts should be inspected to determine if replacement is required.
Pay particular attention to the following:
• Inspect linkage and pivot points for excessive wear.
• Bearing and thrust surfaces of all parts should be checked for excessive wear and scoring.
• Check for broken seal rings, damaged ring lands and damaged threads.
• Inspect seals for damage.
• Mating surfaces of castings should be checked for burrs. Irregularities may be removed by lapping the surface with
emery paper laid on a flat surface, such as a piece of plate glass.
• Castings should be checked for cracks and porosity.
1.3 7C2 Automatic Transmission – 4L60E –
Electrical Diagnosis
For transmissions fitted to V6 engines, the electrical diagnosis is in this Section. A new electrical circuit and control
module has been introduced for automatic transmissions fitted to the V6 engines.
1.4 7C3 Automatic Transmission – 4L60E – Hydraulic and Mechanical Diagnosis
Information contained in 7C3 Automatic Transmission – 4L60E – Hydraulic and Mechanical Diagnosis will assist in the
diagnosis of the mechanical and hydraulic components in the 4L60E automatic transmission, while the transmission
remains installed on the vehicle.
Examples of the type of diagnostic information contained within this section are:
• transmission functional test,
• line pressure information,
• transmission fluid diagnosis,
• symptom diagnosis and
• shift speed charts.
1.5 7C4 Automatic Transmission – 4L60E –
On-vehicle Servicing
Information in 7C4 Automatic Transmission – 4L60E – On-vehicle Servicing covers transmission fluid level checking, as
well as specific information for servicing some components while the transmission remains installed on the vehicle. This
Section also covers the transmission removal and reinstallation to the vehicle.

5 Service Notes
In the interests of safety to personnel, equipment and to the vehicle and its components, read and adhere to the following
notes whenever servicing operations are to be carried out on the Hydra-matic 4L60E automatic transmission. In addition,
some of this information also refers to sound workshop practices and, to achieve the design life of affected components.
Fasteners
• Always reinstall fasteners in the same locations as they were removed.
• If a fastener requires replacement, always use a part of the correct part number or of equal size and strength or
stronger.
General Workshop Practice
• Keep work area and tools clean.
• To avoid unnecessary contamination, always clean the exterior of the transmission before removing any parts.
• Do not use wiping cloths or rags because of the risk of lint being trapped in the transmission.
• Do not use solvents on:
• neoprene seals,
• composition faced clutch plates, or
• thrust washers.
• Always wear eye protection when using compressed air.
• Blow out all passages with compressed air. Only probe small passages with soft, thin wire.
• Handle parts with care to avoid nicks and scratches.
• Do not remove Teflon oil seal rings unless damaged or performing a complete overhaul.
• Expand internal snap rings and compress external snap rings to maximise retention and security.
• Lubricate all internal parts with transmission fluid (only use Dexron® III), as they are being installed.
• When installing cap screws into aluminium castings:
• always use a torque wrench and
• stripped or damaged threads in aluminium castings may be reconditioned by using commercially available
thread inserts.
• Once removed, replace all gaskets, seals and O-rings with new parts.
• Always use seal protectors where indicated and do not use gasket cement or sealant on any joined face unless
specified to do so.
