Engagement delay is the time delay in seconds that it takes one to feel the slight engagement of the automatic transmission assembly into gear. The engagement delay test starts when the automatic transmission gearshift selector is moved from the PARK to the REVERSE or DRIVE positions. This test can also be performed by starting in the NEUTRAL position and then shifting to the DRIVE or REVERSE positions. Engagement delay times can be used to diagnose the hydraulic system and internal clutch conditions/concerns.

1. Chock all 4 wheels and fully apply the parking brake in order to prevent any vehicle movement during testing.

Important: 

•	Perform each test 3 times and take the average value.

•	Maintain a time interval of greater than 1 minute between engagement delay tests. The purpose of the 1 minute delay is to remove any clutch fluid pressure is left in the circuit.

2. Begin the test by using a time recording device, starting the device at the moment when the automatic transmission gearshift selector is moved from either the PARK or the NEUTRAL position to either the REVERSE or the DRIVE position.
3. The time recording device is stopped at the exact moment that the automatic transmission is felt to have engaged into the selected gear.
