Ford 4-Speed Automatic Transmission Pan ID Chart - AOD, AODE, E4OD, A4LD

This document is a transmission identification chart titled "Four-Speed Ford Automatics." It shows the oil pan gasket outlines (pan shapes) of four families of Ford four-speed automatic transmissions, allowing a reader to identify which transmission is installed in a vehicle by comparing the shape of the transmission pan. The four shapes shown are: (1) the A4LD, 4R44E, and 4R55E, which share a tall, narrow rectangular pan with a notched right edge; (2) the AOD, with a roughly square pan; (3) the AODE and 4R70W, which share a similar squarish pan shape; and (4) the E4OD and 4R100, which share a large, wide rectangular pan with a distinctive notch in the lower right corner. Each outline includes the pan bolt hole locations around the perimeter, which can also aid identification by bolt count and spacing. No years, torque values, or part numbers appear on the chart. A reader can use this page to visually distinguish among Ford's four-speed automatic transmissions (A4LD/4R44E/4R55E, AOD, AODE/4R70W, E4OD/4R100) when working under a vehicle or shopping for pan gaskets and filters.
