TIME LAG TEST
This test is to check conditions of clutch, reverse brake and fluid
pressure. "Time lag" means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed in front and behind front and rear wheels re-
spectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from "N" to "D" range
and measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from "N" to "R"
range.
Specification for
time lag
NOTE:
D Make sure that selector cable is propery adjusted.
D When repeating this test, be sure to wait at least minute
after select lever is shifted back to "N" range.
D Engine should be warmed up fully for this test.
Test result
When "N"!"D"
time lag exceeds specification.
When "N"!"R"
time lag exceeds specification.
LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part by
measuring fluid pressure in fluid pressure line.
Line pressure test requires following conditions.
D Automatic fluid is at normal operating temperature (70 – 80_C/
158 – 176_F).
D Fluid is filled to proper level (between FULL and LOW on dip-
stick).
1) Apply parking brake securely and place chocks against wheels.
2) Remove fluid pressure check hole plug bolt (1).
3) Attach oil pressure gauge to fluid pressure check hole in trans-
mission case.

(A) : 09925-37810
CAUTION:
After attaching oil pressure gauge, check that no fluid
leakage exists.
