For sale is a Caterpillar 3116 Engine with Automatic Transmission from a GMC TopKick. That truck was owned by City of Chicago CTA and used as a salter truck. When I bought it, it was not drivable due to extensive rust on frame, caused by its use as a salter. The engine, however, started and ran great. The only thing is that the alternator was frozen (you can hear the main belt rubbing on the alternator pulley). Offered here is this complete engine, with automatic transmission, but without the radiator. None of the external components are guaranteed in any way. The alternator for sure is junk. Please be advised that the engine has sbustantial rust on the outside. See the video here http://www.youtube.com/v/VIFbpSteE4E
