Hydraulic Pressure Tests: Notes
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2002 Mercury Grand Marquis, 2002 Lincoln Town Car, 2002 Ford Crown Victoria, 2001 Mercury Mountaineer, and 2001 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Perform line pressure test before stall speed test. If line pressure is low at stall speed, DO NOT perform stall speed test, or transmission damage will occur.
WARNING:
DO NOT maintain Wide Open Throttle (WOT) in any transmission range for more than 5 seconds, or internal transmission damage may occur.
NOTE:
Pressure test at idle position must be taken with engine at normal operating temperature. Pressure test at WOT position should be taken at full stall speed conditions. Run engine at 1000 RPM with gearshift lever in "N" position for one minute to cool fluid between tests.
