This is page AT-32 from a Nissan automatic transmission service manual section titled "Repair for Component Parts," covering the Forward Clutch (Rear). The page presents an exploded parts diagram (figure SAT459) identifying all components of the forward clutch assembly: the forward clutch (rear) drum, piston seal, piston, springs, spring retainer, snap ring, drive plates, driven plates, retainer plate, waving snap ring, and rear dished plate, with an inset showing the piston, driven plate, and rear dished plate arrangement. A note advises the reader to refer to S.D.S. (Service Data & Specifications) for the number of clutch sheets (drive and driven plates). The text states service procedures for the forward clutch (rear) are essentially the same as those for the high-reverse clutch (front), except for the specified clearance between the retainer plate and snap ring: standard 0.5–0.8 mm (0.020–0.031 in), allowable limit 2.8 mm (0.110 in). Figure SAT323 shows measuring this clearance with a feeler gauge, and figure SAT324 shows checking clutch operation after assembly. Readers can learn component identification, assembly order, and the critical clearance specification for rebuilding this clutch pack.
