TRANSAXLE OIL
Inspection
1. Park the vehicle on level ground.
2. Remove the speedometer cable dust cover, and
disconnect the cable from the speedometer driv-
en gear.
3. After removing the bolt, pull the gear case to re-
move
it
from the housing. (Insert a flat-tipped screw-
driver between the speedometer gear case and
the clutch housing, and use
it
to pry the gear case
loose if necessary.)
4. Check that the oil level is between the "F" and "L".
5. If not, add the necessary amount of the specified
oil through the gear case hole.
Replacement
1. Park the vehicle on level ground.
2. Remove the speedometer driven gear.
(See "Inspection" section above.)
3. Remove the drain plug, and drain the oil.
4. Replace the drain plug, and add the necessary
amount of the specified oil through the speedom-
eter gear case hole.

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.
