Additional Notes

  • All six configurations of the Ford F-150 11th Gen. (USA) covered in these specifications share an identical manual transaxle fluid capacity of 3.5 liters, regardless of engine displacement, drivetrain layout, or fuel type.
  • A 3.5-liter transaxle fill capacity is consistent with a service fill level, meaning the amount of fluid required during a routine drain-and-refill service rather than a full overhaul or dry-fill of a new unit.
  • The 4.2 V6 configuration carries a narrower model year range of 2005-2008, while all V8 configurations span the full 2004-2008 range covered by these specifications.
  • The 6-month check interval applies uniformly across all listed configurations under normal use conditions, meaning the fluid level is to be inspected twice per year rather than only at mileage-triggered service points.
  • A time-based check interval of 6 months, rather than a mileage-based one, reflects the nature of manual transmission fluid monitoring, where fluid level can drop due to seal seepage or minor leaks independent of distance driven.
  • The 4x4 variants, including both the standard 5.4 V8 4x4 and the 5.4 V8 4x4 Flex Fuel, share the same 3.5-liter transaxle capacity and 6-month check interval as the two-wheel-drive configurations, indicating no difference in manual transaxle service requirements between drivetrain layouts.
  • The Flex Fuel designation on the 5.4 V8 4x4 Flex Fuel configuration refers to the engine's compatibility with ethanol-blended fuels, though the manual transaxle fluid specifications for that variant are identical to the non-Flex Fuel 5.4 V8 4x4.
