  • MANUAL TRANSMISSION – DIFFICULT TO SHIFT COLD – 0 TO 40 DEGREES F (-18 TO 4 DEGREES C)
Publication Date: July 29, 2008

FORD:
2008 F-Super Duty

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® MERCON®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.
