7. Recheck the continuity of the individual terminals.
WATER TEMPERATURE SWITCH
Inspection
1. Remove the water temperature switch.
2. Place the switch in water with a thermometer and
heat up the water gradually.
3. Check the continuity of the terminals. If necessary
replace the switch.

6. Ensure that the ATF level is between the F and L
marks. Add ATF to specification, if necessary.
Low temperature scale:
20°C (68°F)
High temperature scale:
65°C (149°F)
ATF type:
Dexron II or M HI
Inspection of Condition
1. Check the ATF for discoloration.
2. Check the ATF for any unusual smell.
Note
Determine whether or not the automatic trans-
mission should be disassembled by observ-
ing the condition of fluid carefully.
If the fluid is muddy and varnished, it indicates
burned drive plates.
SELECTOR LEVER
Inspection
1. Check that the selector lever can only be shifted
as shown in the figure.
2. Make sure there is a click at each range when shift-
ed from P <-> L or P <-» 1 range.
3. Check that the position of the selector lever and
the indicator are exact.
4. Check that the button returns smoothly when used
to shift the selector.
Adjustment
1. Loosen locknuts A, B, and lockbolt C.
2. Shift the selector lever to P range.
3. Shift the transaxle to P range by moving the man-
ual shaft of the transaxle.
4. While holding the selector lever forward in P range,
tighten lockbolt C to the specified torque.
Tightening torque:
8—11 N-m (80—110 cm-kg, 67—95 in-lb)

spacer.
6. Tighten locknut B to the specified torque.
Tightening torque:
8—11 N m (80—110 cm-kg, 67—96 in-lb)
7. Shift the selector lever to N range.
8. With the button on the selector lever knob pressed,
push the selector toward R range with a force of
20 N (2 kg, 4.4 lb) and check the amount of move-
ment (a) at the selector lever knob.
9. Pull the selector lever toward D range in the same
manner and check the amount of movement (b).
10. Verify the stroke difference of (a) and (b) is as
specified.
Stroke difference: 8 mm (0.315 in) max.
Note
If not with in specification, readjust locknuts
A and B.
11. Check the selector lever operation.
(Refer to Inspection section.)
