Neutral Coast Down Speed Test
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
To carry out this test, proceed as follows:
- Drive at a higher rate of speed than where the concern occurred when carrying out the Slow Acceleration Test.
- Place the vehicle in NEUTRAL and coast down past the speed where the concern occurs.
- The concern is vehicle speed-related if duplicated while carrying out this test. This eliminates the engine and the torque converter as sources.
- If the concern was not duplicated while carrying out this test, carry out the Downshift Speed Test to verify if the concern is engine speed-related.
- Proceed as necessary.
