ISSUE
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.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1.
Use the 2008 F-Super Duty Workshop Manual (WSM), Section 308-03: Manual Transaxle / Transmission - ZF 6-Speed - Transmission Draining
and Filling.
2.
Drain the fluid from the transmission oil cooler and lines.
3.
Continue to follow WSM, Section 308-03 to properly fill the transmission to the correct level using Motorcraft(R) MERCON(R)V Automatic
Transmission and Power Steering Fluid.
4.
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.
