When the locknuts are moved, line pressure is in-
creased or decreased as shown. Adjust the lock-
nuts to the correct position using the following
procedure.
(1) Initially install the locknuts fully away from the
throttle cam. (Loosen the cable all the way)
(2) Adjust the locknuts in a clockwise direction as
viewed from the front of the vehicle until the
line pressure begins to increase above the
specification shown below.

TROUBLESHOOTING
GENERAL NOTE
In the event of a problem with the automatic transaxle, the cause may be in the engine, powertrain,
hydraulic control system, or electrical control system. When troubleshooting, it is recommended to
begin from those points that can be judged quickly and easily. The recommended troubleshooting
sequence is described below.
STEP 1: PRELIMINARY INSPECTION Check preliminary items • ATF level and condition
• Oil leakage • Selector lever position
• Vacuum leakage
• Idle speed and ignition timing
• Tire inflation pressure • Inhibitor switch
This step checks conditions surrounding the automatic
transaxle.
STEP 2: STALL TEST Check engine stall speed This step checks the powertrain.
• Friction element slipping
• Torque converter capacity
STEP 3: TIME LAG TEST Check time lag of oil pressure supply This step checks operation of the hydraulic control system. • Friction elements slipping
• Regulating valves
STEP 4: ROAD TEST Check items on road test
• Shift point • Shift schedule
• Kick-down • Shift shock
This step checks functions of the electrical control system
and hydraulic control system.
STEP 5: OIL PRESSURE TEST Check line pressures and governor pressure This step checks major points of the hydraulic control system.
• Oil pump • Line pressure control • Governer pressure control
By following the above five 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 7C—9 to 7C—11.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 54
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.

4. Vacuum Leakage
Check for vacuum leakage.
(1) Disconnect the vacuum hose to the vacuum
diaphragm.
(2) Connect a vacuum pump to the hose.
(3) Apply vacuum and check if vacuum leaks.
(4) If vacuum leaks, check the vacuum hose and
vacuum diaphragm. Replace if necessary.
5. Idle Speed and Ignition Timing
Check idle speed and ignition timing. (Refer to Sec-
tion 4A.)
6. Tire Inflation Pressure
Check tire inflation pressure. (Refer to page 12—2.)
7. Inhibitor Switch
Check the inhibitor switch for operation. (Refer to
page 7C—23.)
