REASON:
PARTS AFFECTED:
INTERCHANGEABILITY:
Ford Motor Co. eliminated one of the checkballs in the 5R55N transmission as a running change
during the 2000 model year. Early version, which requires 3 checkballs, is illustrated in Figure 1,
and the late version, requires 2 checkballs, as shown in Figure 2.
Improved driveability and pleaseability.
VALVE BODY CASTING - The valve body casting changed in the location of the checkball that
was eliminated, as shown in Figure 1 and 2.
VALVE BODY SPACER PLATE - The valve body spacer plate was modified to accommodate the
elimination of the one checkball, as shown in Figure 1 and 2.
The spacer plates "Cannot" be interchanged between the early and late style valve bodies.
The "Late Style" valve body and spacer plate as a package will retro-fit back on all models of the
5R55N transmission and is recommended.
