Time Lag Test: Notes
- Engine and transmission must be at normal operating temperature. Start engine and ensure idle speed RPM is within specification withA/C off. Apply service and parking brakes. Block all 4 wheels. Using a stop watch, measure amount of time until engagement shock is felt when gear selector lever is shifted from "N" to "D" position.
- Allow one minute intervals between tests. Perform time measurements 2 more times and calculate average value. Time lag to "D" position should be less than .7 second. Repeat test procedure to test time lag when gear selector lever is shifted from "N" to "R" position. Time lag should be less than 1.2 seconds.
