Time Lag Test
AUTOMATIC TRANSMISSION
6. Time Lag Test
A: INSPECTION
NOTE:
When the select lever is shifted while the engine is
idling, there will be a certain time elapse or lag be-
fore shock is felt. Using this, check the condition of
forward brake, reverse brake, 1st one-way clutch,
forward one-way clutch and 3rd one-way clutch.
•Perform the test at normal operation fluid tem-
perature of 70 — 80°C (158 — 176°F).
•Be sure to allow a one minute interval between
tests.
•Make three measurements and take the average
value.
1) Fully apply the parking brake.
2) Start the engine.
Check the idle speed (A/C OFF).
3) Shift the select lever from “N” to “D” range. Using
a stop watch, measure the time-lag from shifting
the lever until the shock is felt.
Time-lag
Specification: 1.2 sec. or less
If “N” → “D” time-lag is longer than specification:
•Line pressure too low
•Forward brake worn
•One–way clutch not operating properly
4) In the same manner, measure the time lag of “N”
→ “R”.
Time-lag
Specification: 1.5 sec. or less
If “N” → “R” time lag is longer than specification:
•Line pressure too low
•Reverse brake worn
