Time Lag Test: Preparation
Check and adjust coolant, engine oil and ATF levels. Warm engine and transaxle to normal operating temperature. Block front and rear wheels on both sides. Set parking brake. Ensure engine idle speed and ignition timing is correct. See appropriate ON-VEHICLE ADJUSTMENTS article in ENGINE PERFORMANCE.
This test measures time lag between selecting specific gear and actual transaxle shift. Test checks condition of the 1-2, N-R and N-D accumulators, forward and one-way clutches, 2-4 brake band and low-reverse brake.
