Shift Valve Body Assemble





Important:
^ Transmission damage may occur when control valve assembly springs and other parts are mistakenly interchanged. Interchanging parts can be avoided by the following:
^ Tag each part as it is removed.
^ Use J 33163 to organize parts and to simplify correct valve body reassembly.
Protect control valve assembly parts from damage observing the following precautions
^ Handle all valves carefully.
^ Protect control valve assembly parts during removal, cleaning, inspection, and reassembly.
^ Keep parts in a clean container until the parts are installed.
