Automatic Transmission (Possibly TH350 or TH400 type)

The item appears to be an automatic transmission from a vintage or classic vehicle, likely a General Motors model from the late 1960s to 1980s, such as a Turbo-Hydramatic 350 (TH350) or 400 (TH400) given its general form factor. It is made of cast aluminum alloy for the main case, exhibiting a dull, oxidized gray finish indicative of age and outdoor exposure. The transmission features a prominent bellhousing that tapers significantly towards the rear, where the output shaft housing extends. The bellhousing appears to be an integrated part of the transmission case. Visible within the bellhousing is the flywheel or flexplate, which is heavily rusted, displaying a deep reddish-brown color, and has external gear teeth. Several bolts, also rusted, are visible attaching to what would be the torque converter mounting points. The exterior of the case shows significant weathering, including scratches, dirt accumulation, and some minor impact marks or abrasions. There are no clear manufacturer's marks or identifying stamps immediately visible in the provided image; however, such markings are typically cast into the body of the transmission or stamped on an identification tag which isn't apparent. The overall condition suggests it has been stored outdoors for an extended period, leading to the notable corrosion on the flexplate and general grime on the housing. Its weight and size indicate it's from a full-size passenger car or light truck. The general construction points to robust engineering typical of its period. The absence of a visible torque converter, pan, and other ancillary components implies it's either incomplete or disassembled for parts/storage. The long tailshaft portion is characteristic of 2WD applications, but without further views, it's hard to definitively tell.
