Tranny ID help needed

3681843 is trans I.D. number. trans is a 1974

4661 is build date. 5-1-1974

5741 is the sequence # I believe

for future reference go to: http://www.mymopar.com/downloads/transguide.pdf

this is a listing of trans I.D. numbers.

the other numbers you posted I don't think really mean anything.

hope this helps
if anything I would say that the 5741 number would be the build date?
you said the build date is 5-1-1974 and that number is 5 for 5th month 74 for year and 1 for day?

\and 4661 would be the sequence number if thats the case?

im no expert,just asking questions is all
