Ford F4E-III
Valve-Body Changes
|
Change:
At the start of production for the 1998 model
year, the F4E-III valve body was redesigned.
Reason:
For better line pressure and torque-converterclutch
control.
Parts Affected:
• The pressure-control solenoid, solenoid body,
spacer plate and gaskets were changed. The pressure-
modifier valve also was changed and a spring
was added to the end of the valve, and an adjustable
bore plug replaced the old retainer. Refer
to Figure 1 for the previous-design parts and
Figure 2 for the new-design parts as well as the
new pressure-modifier valve line-up.
• The upper side of the main valve body was
changed to accommodate the new pressure-control
solenoid body and spacer plate. Refer to Figure 3.
• The lower side of the main valve body was
changed to incorporate a new solenoid-reducing
valve. See Figure 4 for the previous design and
Figure 5 for the new design.
