Time Lag Test
- Engine and transmission must be at normal operating temperature. Start engine and ensure idle RPM is within specification with A/C off. Apply service and parking brakes. Using stop watch, measure time until engagement shock is felt when 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 should be less than 1.2 seconds. Repeat test procedure to test time lag when selector lever is shifted from "N" to "R" position. Time lag should be less than 1.5 seconds. If results are not within specification, inspect internal components.
