Time Lag Test

WARNING: This page is about a different variant/trim than selected.

Perform mechanical system test preparation. (See MECHANICAL SYSTEM TEST PREPARATION ).
Start the engine and warm up the engine until the ATF temperature reaches 60-70 °C {141-158 °F} .
Shift the selector lever from N position to D range.
Use a stopwatch to measure the time it takes from shifting until engagement is felt. Take 3 measurements for each test and average the results using the following formula.

Perform the test for the following shifts in the same manner.
- N position-->R position
  Average time lag
  
  N position-->D range: 0.4-0.7 sec.
  
  N position-->R position: 0.4-0.7 sec.

Evaluation of time lag test

EVALUATION OF TIME LAG TEST

Condition		Possible cause
N-->D shift	More than specification	Low line pressure Forward clutch slipping Oil leaking from forward clutch fluid circuit Shift solenoid A not operating properly
N-->D shift	Less than specification	Forward accumulator not operating properly Shift solenoid A not operating properly Excessive line pressure
N-->R shift	More than specification	Low line pressure Low and reverse brake slipping Reverse clutch slipping Shift solenoid B not operating properly
N-->R shift	Less than specification	Servo apply accumulator not operating properly Shift solenoid B not operating properly Excessive line pressure
