I do know the A500 and A518 share the same Borg Warner overdrive unit

Mmm…no, sir. There is no Borg-Warner overdrive in either of those transmissions. They were in-house designed, in-house built by Chrysler.

D'OH! Dan strikes again. I hadn't looked closely at these transmissions for over a year, so I got it wrong. I just looked closer and it is not Borg Warner, but NEW PROCESS. I knew it was one of those gear companies. Whoops.

New Process was Chrysler's gear operation for quite a long time. In '90 there was a GM tie-in and a rename to New Venture. In '12, the whole outfit closed down. Good history in the Wiki:
