Article No. 88-8-20
LIGHT TRUCK:
1987-88 F SERIES, BRONCO
ISSUE:
A hard shifting transmission during a 2-3 upshift or 4-3 downshift may be caused by a third gear synchronizer that has an improper surface
finish. The hard shifting condition may also cause the transmission to disengage from third gear because of incomplete third gear
engagement.
ACTION:
To correct this, install a new design third gear synchronizer that was manufactured using a new machine lapping process to improve the
surface finish. Refer to the 1988 Light Truck Shop Manual, Section 16-34-1 for removal and installation procedures.
