|2008 F-Super Duty|
Some 2008 F-Super Duty vehicles equipped with a 5.4L or 6.8L engine and a manual transmission may exhibit high shift efforts when shifting into gears at cold ambient temperatures ranging from 0 to 40 degrees F (-18 to 4 degrees C). This is due to the viscosity of the current manual transmission fluid.
Follow the Service Procedure steps to correct the condition.
- Use the 2008 F-Super Duty Workshop Manual (WSM), Section 308-03: Manual Transaxle / Transmission – ZF 6-Speed – Transmission Draining and Filling.
- Drain the fluid from the transmission oil cooler and lines.
- Continue to follow WSM, Section 308-03 to properly fill the transmission to the correct level using Motorcraft® MERCON®V Automatic Transmission and Power Steering Fluid.
- Shifting will improve as the new lubricant works through the manual transmission. The time needed to improve shift efforts may vary by driver and operating conditions.
