Thats not entirely true - there is a 3 pin 518 that uses a 727 converter ( it's a non lockup version ) and I have it bolted up to an early hemi. I didnt want the lockup or the different converter and this was my best option.
They are hard to find, I forget the specifics , but i found one locally as a core.
Never seen a 3 wire non lock up... it would be
sorta strange to have a 3 wire connector to work
just 1 thing in the trans... the single wire was all
I seen as just the OD version.... but I guess you
never know when it comes to Mopar
