This concern is ONLY for vehicles with Ford Quality Remanufactured (FQR) 4R70W Transmission Exchange Units With Julian build dates between
062-97 And 04099 (corresponding serial numbers are between R0475797 and R0771887).
ISSUE
A delayed or no 2-3 upshift, primarily when the transmission is cold, may be evident on some vehicles In some cases, Diagnostic Trouble Code (DTC)
P0782 may also be present. This may be caused by fluid pressure leakage past the larger diameter seal of the 2-3 accumulator.
ACTION
Replace the 2-3 accumulator piston using a revised piston. The revised piston will increase seal/bore interference, eliminating any internal leak relating
to the 2-3 accumulator piston reducing the possibility of 2-3 upshift concerns. Refer to the appropriate Service or Workshop Manual for replacement
procedure.
