AAR, AUTO, Torque Converter Help Needed

So I send my trans off to the shop for rebuild along with the converter. Stress the importance that I get my original pieces back and told "no issue, the torque converter rebuild shop doesn't stock your converter AND I'll request they rebuild yours"

I pick it up today and I notice the converter they provided is missing the drain plug (not mine). The're trying to make it right but I have little faith they will locate my original converter (and hardware, as I recall the plug had markings). He claims if they can't find mine they will find a replacement. So here are my questions

Prior to turn in I wasn't able to find any PN's on my converter, any idea how one would be able to tell a correct one from an incorrect?

Parts manual doesn't show a converter for a 340 3-2bbl, only a 440 3-2bbl (3410839)
Would it have been the same as a 340 4bbl? (2801764), this PN also appears on 318 and 383 models??

Stall speeds as provided in the service manual doesn't address 340 2-6bbl converters at all, so whats the stall for a 340 3-2bbl, same as 340 4bbl (2250-2450)?

Tech service bulletin for AAR's doesn't address this topic either

So what am I suppose to do at this point?????

Thanks for the help

find out where they sent it to and go look for it..most likely on top of the pile of old ones..

Thats actually a good thought, its a local place I'm sure. I'll try calling to get the information tomorrow.

So if I understand this correctly, the same Torque Converter (TC) PN was used on a 318, 340, and 383 4bbl, the stall speed being dictated by the engine torque when applied to the same TC.

So now what remains unknown is if there was any difference between a TC on a 3-2bbl 340 and a 340 4bbl car.

Since the trans ID number (3410969) were all used on 340 engines with 2-3bbl and 4bbl combinations, it seems reasonable the torque converters were identical as well.

I'm still hopeful someone has information to validate what TC went in the AAR's & T/A's, but thought I'd pass along my findings/thoughts

Update - Original located

Glad to hear that you tracked down tour original TC.
