Time Lag Test

  1. Engine and transaxle 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 shift lever is shifted from "N" to "D" position.
  2. Allow one minute intervals between tests. Perform time measurement several times and calculate average time. Time should be less than .7 second. Repeat test procedure to test time lag when shift lever is shifted from "N" to "R" position. Time lag should be less than 1.2 seconds. If test time is not as described, check transaxle line pressure.
