Time Lag Test
TIME LAG TESTIf the shift lever is shifted while the engine is idling, there will be a certain time elapse or lag before the shock can be felt. This is used for checking the condition of the front clutch, rear clutch and brake No.3.
CAUTION:
a. Perform this test with the fluid at normal operating temperature (50 - 80°C or 122 - 176°F).
b. Allow a one minute interval between tests.
c. Make three measurements and calculate the average value.
MEASURE TIME LAG
a. Fully apply the parking brake.
b. Turn off the 4WD change-over switch.
c. Start the engine.
Idle speed (cooling fan and A/C OFF):
w/o PS "N" range 800 rpm
w/o PS "N" range 900 rpm
d. Shift the shift lever from "N" to "D" range.
Using a stop watch, measure the time it takes from shifting the lever until the shock is felt.
Time lag: Less than 1.2 seconds
e. In same manner, measure the time lag for "N" - "R".
Time lag: Less than 1.5 seconds
EVALUATION
a. If "N" "D" time lag is longer than specified,
- Line pressure too low
- Front clutch worn
b. If "N" "R" time lag is longer than specified,
- Line pressure too low
- Rear clutch worn
- Brake No.3 worn
