Engagement Delay Test: Procedure
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Chock all 4 wheels and fully apply the parking brake in order to prevent any vehicle movement during testing.
- 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.
- 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.
- The time recording device is stopped at the exact moment that the automatic transmission is felt to have engaged into the selected gear.
Specifications:
- PARK or NEUTRAL to DRIVE position: Less than 0.7 seconds
- PARK or NEUTRAL to REVERSE position: Less than 1.2 seconds
