How to Change Transmission Oil in an F-150 Triton
by John Stevens J.D.
Ford’s Modular engine, commonly referred to as the “Triton,” was first produced in 1991 and first installed in the F-150 in 1997. The powerful engine requires a durable transmission, and the best way to ensure that the transmission functions properly is to regularly change the transmission fluid. Fortunately, changing the transmission oil in a F-150 equipped with the Triton is a straightforward process.
Step 1
Apply the parking brake and allow the engine at least 30 minutes to cool.
Step 2
Place a container large enough to safely contain approximately 7 qts. of fluid underneath the pan on the bottom of the transmission.
Step 3
Twist the drain bolt on the bottom of the pan in a counterclockwise direction with a socket wrench until the bolt detaches from the pan, then allow the transmission fluid to drain into the container.
Step 4
Insert the transmission pan’s drain bolt into the pan, then twist the bolt in a clockwise direction with the socket wrench until the bolt is tight.
Step 5
Raise the hood and withdraw the transmission’s dipstick.
Step 6
Insert a long funnel into the transmission’s dipstick tube, then pour approximately 6 qts. of Mercon V-type transmission fluid into the funnel.
Step 7
Turn the engine on and allow it to idle for approximately 30 seconds, then turn the engine off.
Step 8
Insert the transmission’s dipstick into the transmission, then withdraw the dipstick and check the fluid level.
Step 9
Add transmission fluid until the fluid level reaches the “FULL” mark on the dipstick.
