Nissan Automatic Transmission Low & Reverse Brake Inspection - Exploded Diagram

This page (AT-33) from a service manual's 'Repair for Component Parts' section covers the Low & Reverse Brake assembly of an automatic transmission. It features an exploded-view diagram (figure SAT325) identifying the components of the low and reverse brake in assembly order: piston, piston retainer, alternating drive plates and driven plates, retainer plate, and snap ring. The inspection procedure instructs the technician to examine the low and reverse brake for damaged clutch drive plate facing and a worn snap ring, and to check drive plate facing for wear or damage, replacing parts if necessary. Key specifications given are drive plate thickness: standard 1.90 - 2.05 mm (0.0748 - 0.0807 in), with an allowable (wear) limit of 1.8 mm (0.071 in). A reader can learn the component layout of the brake pack, which parts to inspect during transmission overhaul, and the measurable criterion for deciding whether drive plates must be replaced. The page contains no vehicle year, model, or engine identification, though the styling and 'SAT' figure code are consistent with a Nissan service manual automatic transmission (AT) section.
