Time Lag Test

If the selector lever is shifted while the engine is idling, there will be a certain time lapse, or time lag, before shock is felt. This step measures the time lag to check the condition of the N-D, 1-2, and N-R accumulators, forward and one-way clutches, 2 - 4 brake band, and low and reverse brake.




Preparation
Perform the preparation procedure outlined in STALL TEST. Stall Test

Procedure
1. Start the engine.
2. Check the idle speed and ignition timing in P range.

Idle speed:
B6 SOHC 700 - 800 rpm
K8 DOHC 640 - 700 rpm

Ignition timing (BTDC): 9 - 11 °
(TEN terminal of diagnosis connector grounded)

3. Shift from N range to D range.
4. Use a stopwatch to measure the time it takes from shifting until shock is felt.

CAUTION: Idling for at least one (1) minute cools the ATF and prevents its deterioration

5. Shift the selector to N range and run the engine at idle speed for at least one (1) minute.

NOTE: Make three measurements for each test and average the results.

6. Perform the test for the following shifts in the same manner.
1. N -> D range
2. N -> D range (hold mode)
3. N -> R range

Time lag:
N -> D range 0.5 - 0.6 second
N -> R range 0.6 - 0.7 second
