Maintenance and Specifications 3. With the parking brake engaged and your foot on the brake pedal, start the engine and move the gearshift lever through all of the gear ranges. Allow sufficient time for each gear to engage. 4. Latch the gearshift lever in P (Park) and leave the engine running. 5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If necessary, refer to Identifying components in the engine compartment in this chapter for the location of the dipstick. 6. Install the dipstick making sure it is fully seated in the filler tube. 7. Remove the dipstick and inspect the fluid level. The fluid should be in the designated area for normal operating temperature or ambient temperature. Low fluid level Do not drive the vehicle if the fluid level is at the bottom of the dipstick and the ambient temperature is above 50°F (10°C). Correct fluid level The transmission fluid should be checked at normal operating temperature 150°F-170°F (66°C-77°C) on a level surface. The normal operating temperature can be reached after approximately 20 miles (30 km) of driving. You can check the fluid without driving if the ambient temperature is above 50°F (10°C). However, if fluid is added at this time, an overfill condition could result when the vehicle reaches normal operating temperature. The transmission fluid should be in this range if at normal operating temperature (150°F-170°F [66°C-77°C]). The transmission fluid should be in this range if at ambient temperature (50°F-95°F [10°C-35°C]). 285 2005 F-150 (f12) Owners Guide (post-2002-fmt) USA (fus)
