Diesel Bombers - Need help identifying this tourque converter!

Had a costumer come in with a 06 Dodge he had just bought from a used car dealer and the tranny went out on him about a month after he bought it! Anyway looking under the hood its all stock now, but it has been modified in the past! Anyway we pulled the trans and found that the tourque converter is aftermarket but I have no idea what it is! He is going to put a new trans in it and he does not want this tourque converter so he said we could keep it! I would really like to know what it is if anyone can help me! the pic I took of the sticker is blurry but it says 5451HD and under that a date 03/16/07 and ofcourse under that it says removal of this sticker will void warrenty. That is all I can find on the whole thing. Any help is much appreciated!!! Thanks!!!
