Disassembly And Assembly: Assembly

Before assembling the valve body, thoroughly clean all of the components with a suitable solvent and blow them dry with 344 kPa (50 psi) regulated  shop air. Clean the work surface and lay out a clean lint free cloth to avoid contaminating the clean valve body components. Lay the valve components out on the cloth in the order they will be installed in the valve body. The cloth will hold the valve components in place and keep them from rolling out of position. A light coating of the proper transmission fluid may be applied to each component as the valve body is assembled.

  1. Install the springs, Pressure Control Valves, plug valves, and plugs into their bores in the inner valve body.
  2. Install the Limp Home Mode latch valve, spring, and plug into its bore in the inner valve body.
  3. Install the solenoid limit valve, spring, and plug into its bore in the inner valve body.
  4. Install the boost valve, spring, and plug into its bore in the inner valve body.
  5. Turn the inner valve body so the plugs are facing upward.
  6. While pressing downward on the plugs, install the spring clips to retain the plugs in the inner valve body.
