TRANSMISSION VALVE BODY COMPONENTS
DESCRIPTION
Transmission operating pressure is supplied to the
clutch and brake apply circuits through the transmis-
sion valve body. The valve body consists of an upper
body, lower body, separator plate and upper and
lower gaskets (Fig. 14). The various spool valves,
sleeves, plugs and springs are located within the two
body sections.
The manual valve, 1–2 shift valve, primary regula-
tor valve, accumulator control valve, check balls, and
oil strainers are located in the lower body section
(Fig. 15). The remaining control and shift valves plus
check balls and one additional oil strainer are located
in the upper body section (Fig. 16).
TRANSMISSION VALVE BODY SOLENOIDS
The solenoids are mounted on the valve body and
operated by the TCM. The solenoids control operation
of the converter clutch and shift valves in response to
input signals from the module.
