ENGINE OIL
REPLACEMENT
1. Warm up the engine to the normal operating tem-
perature and stop it.
2. Remove the oil filler cap and the oil pan drain plug.
3. Drain the oil into a suitable container.
Warning
Be careful when draining, the oil is very hot.
4. Install the drain plug and a new gasket.
Tightening torque:
29—41 N-m (3.0—4.2 m-kg, 22—30 ft-lb)
5. Refill the engine with the specified type and amount
of oil.
6. Refit the oil filler cap.
Oil pan capacity:
5.0 liters (5.3 US qt, 4.4 Imp qt)
7. Recheck the oil level after the engine has been run.

OIL
FILTER
REPLACEMENT
1. Remove the oil filter with a suitable wrench.
2. Use a clean rag to wipe off the mounting surface
on the engine.
3. Apply a coat of engine oil to the filter rubber seal.
4. Install the oil filter until the rubber seal contacts the
oil cooler by hand. Then tighten it a 7/6 turn fur-
ther with a band type wrench.
5. Start the engine and inspect around the filter seal
for leaks.
6. Check the oil level and add oil if necessary.
Oil filter capacity:
0.50 liters (0.52 US qt, 0.44 Imp qt)

TROUBLESHOOTING (G4A-HL) 7B
TROUBLESHOOTING (G4A-HL)
GENERAL NOTE
In the event of a problem with the automatic transaxle, the cause may be in the engine, power train,
hydraulic control system, or electrical control system.
When troubleshooting, therefore, it is recommended to begin from those points that can be judged
quickly and easily. The recommended troubleshooting sequence is described below.
STEP 4: TIME LAG TEST
Check time lag of oil pressure supply
STEP 6: OIL PRESSURE TEST Check line, throttle, and governor pressures
This step checks conditions surrounding the automatic
transaxle.
This step checks the electrical control system.
• Function of the electrical control system
• Components
This step checks the power train. • Friction element slipping • Torque converter capacity
This step checks operation of the hydraulic control system. • Accumulators • Friction elements slipping • Regulating valves
This step checks functions of the electric control system and
hydraulic control system.
This step checks major points of the hydraulic control system.
• Oil pump • Line pressure control • Throttle pressure control
• Governer pressure control
STEP 5: ROAD TEST Check items on road test
• Shift point • Shift schedule
• Kick-down • Shift shock • Lock-up and overdrive inhibition
By following the above 6 steps, the cause of the problem should be located.
As another guide to faster location of the causes of problems, the Quick Diagnosis Chart is included
at pages 7B—42, 43.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 20
types of problems. It is only necessary to check those components indicated by circles, at each step
of the troubleshooting process, in order to quickly locate the cause of the problem.
