This scanned page from an automotive service manual contains two exploded/location illustrations concerning an automatic transmission boost valve assembly. Fig. 269, "Boost Valve Cover Location" (illustration reference J9321-467), shows the valve body with two callouts: (1) the boost valve housing and cover, and (2) the boost valve tube, indicating where the boost valve assembly is located on the valve body. Fig. 270, "Boost Valve Components" (illustration reference J9321-468), is an exploded view showing the six components of the boost valve assembly in disassembly order: (1) spring and valve retainer, (2) cover screws, (3) boost valve cover, (4) boost valve plug, (5) boost valve, and (6) boost valve spring. A reader can use this page to identify the location of the boost valve on the transmission valve body and to identify and correctly order each individual component when disassembling or reassembling the boost valve. Surrounding procedural text from the opposite side of the page bleeds through the scan but is not legible. No year, make, model, torque specifications, or part numbers are stated on the page other than the figure/illustration reference numbers J9321-467 and J9321-468.
