MANUAL ROAD TEST
This test check the gear being used in ªLº, ª2º or ªDº range when
driven with unoperated gear shift control system. Test drive vehicle
on a level road.
NOTE:
Before this test, check diagnostic trouble code (DTC).
1) Disconnect coupler of shift solenoid valves on transmission.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid
valves coupler.
2) With select lever in ªPº, start engine and warm it up.
3) With select lever in ªLº range, start vehicle and accelerate to 20
km/h (12.5 mile/h). Check in this state that 1st gear is being
used.
4) At 20 km/h (12.5 mile/h), shift select lever to 2 range and acceler-
ate to 40 km/h (25 mile/h). Check in this state that 3rd gear is
being used.
5) At 40 km/h (25 mile/h), shift select lever to D range and check
that O/D gear is used when speed is higher than 40 km/h (25
mile/h).
6) After above checks, stop vehicle then engine, and connect shift
solenoids coupler with ignition switch OFF.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when connecting shift solenoid valves
coupler.
7) Clear DTC with scan tool.
TIME LAG TEST
This test is to check conditions of clutch, reverse brake and fluid
pressure. ªTime lagº means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels re-
spectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from ªNº to ªDº range
and measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from ªNº to ªRº
range.
Specification for ªNº
ªDºLess than 1.2 sec.
time lagªNº
ªRºLess than 1.5 sec.
NOTE:

When repeating this test, be sure to wait at least minute
after select lever is shifted back to ªNº range.

Engine should be warmed up fully for this test.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature performed after repair or
fluid change before test driving is just preparation for level check of
normal operating temperature. The checking procedure itself is the
same as that described previously. If the fluid level is between FULL
COLD and LOW COLD, proceed to test drive. And when the fluid
temperature has reached the normal operating temperature, check
fluid level again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) With engine is cool, remove drain plug from oil pan and drain A / T
fluid.
3) Install drain plug.
