DESCRIPTION AND OPERATION (Continued)

TRANSMISSION VALVE BODY COMPONENTS

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.
