WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If the line pressure is low at stall, do not carry out the Stall Speed Test or further transmission damage will occur. Do not maintain Wide Open Throttle (WOT) in any transmission range for more than 5 seconds.
This test verifies that the line pressure is within specification.
- Connect the Transmission Fluid Pressure Gauge to the line pressure tap using an M10 X 1.00 fitting.
- Start the engine and check the line pressures. Refer to the Line Pressure Chart to determine if the line pressure is within specification.
NOTE:
The line pressure tap is an M10 X 1.00 thread. Do not use a National Pipe Thread (NPT) fitting when installing a pressure gauge. If a NPT
fitting is used, damage to the transmission case will occur.
