Disassembly (fig. 5-74) NOTE All related items not covered in a and b below or in separate rebuild sections, were removed from the transmission as outlined in paragraph 5-6, steps 40 through 45 (fig. 5-40 through 5-45). No further disassembly of those parts is required. a. Intermediate-Range Clutch Piston Housing Assembly (fig. 5-74). (1) Remove 12 springs (34) from housing assembly (25) only if replacement is necessary. (2) Tap housing assembly to loosen piston assembly (22), and remove piston assembly. (3) Remove outer seal ring (20) and expander (21) from outer groove of piston. WARNING Do not dispose of Teflon seals by burning; toxic gases are produced. (4) Remove inner seal ring (24) and expander (23) from inner groove of piston. b. Low- and Reverse-Range Clutch Piston Housing Assemblies (fig. 5-74). (1) Tap housing assembly (fig. 5-76) lightly to loosen low-range clutch piston assembly, and remove piston assembly. (2) Remove reverse-range clutch piston (47) in the same manner. (3) Remove outer seal ring (49) and expander (48) from low-range clutch piston. (4) Remove outer seal ring (1, fig. 5-75) and expander (2, fig. 5-75) from reverse-range clutch piston (3, fig. 5-75).
