What does this Ford AOD diagram show?

It shows the oil (hydraulic) circuit of the Ford AOD transmission in 1st Gear at Closed Throttle with the selector in the "OD" Range, including which clutch is applied and how fluid routes through the valves, servos, and accumulators.

Which pressures are identified in the diagram's legend?

The Pressures legend identifies Throttle (T.V.), Line, Converter, Regulated, and Pump Inlet pressures, plus arrow symbols for Exhaust and Cooler And Lube flow.

What clutch is applied in 1st gear closed throttle OD range on the AOD?

The diagram marks "APPLIED" at the forward clutch area, indicating the forward clutch is applied in this condition.

What vehicle does this AOD oil circuit diagram apply to?

The document states it is for a 1987 Ford LTD Crown Victoria (Ford AOD transmission).

What valves are shown in the AOD hydraulic circuit?

It includes the main oil pressure regulator, oil pressure booster, converter relief, manual valve, throttle valve, T.V. limit and relief valves, 1-2/2-3/3-4 shift valves, 3-4 shuttle valve, 2-1 scheduling valve, 2-3 and 3-4 backout valves, capacity and TV modulator valves, orifice control valve, OD servo regulator valve, and low servo modulator valve, plus the governor assembly.

This document is an oil (hydraulic) circuit diagram for the Ford AOD automatic transmission, labeled Fig. 4: 1st Gear (Closed Throttle) - "OD" Range, published for a 1987 Ford LTD Crown Victoria (diagram reference G97C03226, copyright 2003 MRIC, LLC). It shows fluid routing through the transmission when the selector is in Overdrive with the vehicle in 1st gear at closed throttle. The diagram identifies which friction elements are applied (marked "APPLIED" near the forward clutch) and traces circuits among major components: the pump, screen, sump, main oil pressure regulator valve, oil pressure booster valve, converter relief valve, cooler and lube circuits, manual valve (PRND31), throttle valve/plunger/plug, T.V. limit and relief valves, governor assembly, 1-2/2-3/3-4 shift valves, shuttle, backout, scheduling, capacity and TV modulator valves, accumulators (1-2, 2-3, 3-4), and the intermediate, reverse, forward, and direct clutches plus OD and reverse servos. A pressure legend distinguishes Throttle (T.V.), Line, Converter, Regulated, and Pump Inlet pressures along with exhaust and cooler/lube flow symbols. Numbered callouts (1–17) mark specific valves and components. Readers can use it to understand or diagnose AOD hydraulic operation in 1st gear closed-throttle conditions.
