Summary
This bulletin supersedes 25-2587. Reason For Update: update the Parts list to add the F-clutch friction plates HL3Z-7B164-D
and the F-clutch steel plates PR3Z-7B164-A for the proper vehicle lines, replace the transfer case mounting bolt part number from W714288-S438 to W714288-S437, update the part number W720688-S439 quantity from 2 to 1, update the part number ML3Z-7869-C claim quantity from 2 to 1 (only if necessary), update the description of CXT-10-LV6 and XT-10-QLVC by adding "transfer case fluid, 4WD only", move HL3Z-7A191-B and L1MZ-7F396-A fluid pan gaskets to the parts to inspect and replace list, and remove TL1Z-6775-A self adhesive heat shield from the F-150/Expedition/Navigator parts list as it is not a discard item. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177).
