TRANSIMISSION FLUID LEVEL AND
CONDITION
Park vehicle on level ground and set parking brake.
With the engine idling, move the shift lever through all
positions from "P" to "L", then return to position "P".
Check to see If the level of fluid comes to "HOT" range
of about 80
°
C (176
°
F) on the dipstick gauge.
If the level of fluid is too low, replenish to bring it to
maximum level in "HOT" range.
Inspection of fluid condition
If the ATF is black or smells burnt, replace it.
ATF REPLACEMENT
NOTE:
Do not overfill.
1) Remove the drain plug from oil pan and drain the
fluid.
2) Reinstall the drain plug securely.
3) With the engine OFF, add new fluid through the filler
tube.
4) Start the engine and shift the selector into all
position from "P" through "L", and then shift into "P".
5) With the engine idling, check the fluid level. Add fluid
up to the "COLD" level on the dipstick.
6) The ATF level must be checked again for correct
level with the "HOT" level.
NOTE:
To prevent fluid leaks, the drain plug gasket must be
replaced each time this plug is removed.

NEUTRAL START SWITCH INSPECTION
Inspection
With a circuit tester, make a continuity test on the neutral start
switch with the moving piece set in each position.

Continuity
Removal
Preparation:
Disconnect negative (–) battery cable.
1. Remove rear sound cover.
2. Remove the rear side ATF cooler pipe from the
transmission elbow.
3. Disconnect neutral start switch connector.
4. Unstake the lock washer, and then remove the shaft nut.
5. Remove the neutral start switch.
Installation
To install, follow the removal steps in the reverse order, noting
the following points;
Adjustment
1) Loosen the neutral start switch bolt and set the shift
selector to the "N" range.
2) Align the groove and neutral basic line.
3) Hold in position and tighten the bolt.

BRAKE SIGNAL INSPECTION
Check that the brake light comes on when the brake pedal is
depressed.
VEHICLE SPEED SENSOR INSPECTION
1. Connect the Vehicle speed sensor connector terminal (1) to
the battery (+) terminal and terminal (2) to the battery (-)
terminal.
2. Connect a resistance of 1.3k ohm to 5k ohm (1.4W or
more) between terminals (1) and (3).
NOTE:
Be extremely careful not to connect the battery (+) terminal
to the terminal (3)
This may damage the vehicle speed sensor.
3. Rotate the shaft of the vehicle speed sensor slowly and
measure the voltage at both ends with a digital tester.
Replace the sensor when the result of inspection is found
abnormal.
INPUT AND OUTPUT REVOLUTION
SENSOR INSPECTION
Use an ohmmeter to measure the resistance between
terminals 1 and 2.
The voltage, with one rotation of shaft, fluctuates four
times in the following range: 10 to 14V
⇔
2V or less.
Standard resistance
560 – 680
Ω
(20
°
C)
610 – 740
