This document is a hydraulic oil circuit diagram (Fig. 5) for the Ford AOD automatic transmission, showing fluid flow in 2nd Gear at Part Throttle in the "OD" (Overdrive) range. The header attributes it to a 1987 Ford LTD Crown Victoria and it was printed via a JV AUTO/MRIC service-information system (copyright 2003 MRIC, LLC; printed February 3, 2004). The schematic identifies which friction elements are applied in this operating state — the Intermediate Clutch and Forward Clutch are marked APPLIED — and traces oil passages between all major hydraulic components: pump, screen, sump, main oil pressure regulator valve, oil pressure booster valve, converter and converter relief valve, cooler and lube circuits, manual valve (P R N D 3 1), throttle valve/plunger/plug, governor assembly, 1-2/2-3/3-4 shift valves, shuttle, backout, accumulator, capacity modulator, orifice control, TV limit and TV relief valves, plus the OD and reverse servos and the reverse and direct clutches. A "Pressures" legend distinguishes Line, Governor, Throttle (T.V.), T.V. Limit, Regulated, Pump Inlet, and Converter pressures, plus exhaust and cooler/lube flow arrows. Reference number G97E03227 appears on the drawing. It is one page of a set covering the AOD in various gears and throttle positions, useful for diagnosing AOD shift and pressure problems.
