Yesterday i went to start my 1999 3500 dually with 24v and 47re trans. Being cold outside i let it warm up a little bit. I moved it up about 15 feet when i noticed it was pouring out transmission fluid. The leak looks to be coming from a cylinder shaped canister mounted on the side of the engine on the passenger side behind the turbo close to the rear of the engine. These lines looks to go to the side of the transmission and then to the trans cooler in front of the engine. I'm wondering the correct name for the part on the canister mounted on the side and possibly when to get replacement fittings or seals for it. I would try to search for it, but again dont know the name. Thanks.

 

THat is the oil to coolant cooler.
