Shift Point Road Test

WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

This test verifies that the shift control system is operating correctly.

Bring engine and transaxle up to normal operating temperature.
Operate vehicle with selector lever in D range.

Apply full and half throttle to observe the speeds at which upshift occurs.
