Ford Transmission Pan Identification Chart - C4, C5, C6, AOD, E4OD, 4R70W

This document is a Ford automatic transmission identification chart titled "How to Identify Your Transmission." It shows outline drawings of six different transmission oil pans, each labeled with its bolt count and the transmission model it belongs to. The C4 and C5 transmissions both use 11-bolt pans (distinguished by pan shape), the C6 uses a 17-bolt pan with a tip noting that the rear edge of the C6 pan is S-shaped, the AOD/AOT uses a 14-bolt pan, the E4OD uses a 20-bolt pan, and the AODE-W (also called 4R70W) uses a 14-bolt pan of a different shape than the AOD. A closing note explains that transmissions can be identified by the shape of the transmission pan, the original gasket, and/or the number of pan bolts. A reader can use this chart to determine which Ford automatic transmission is installed in their vehicle by counting the pan bolts and comparing the pan outline shape, which is useful when ordering filters, gaskets, or rebuild parts. The document itself lists no specific vehicle years, models, or part numbers.
