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: https://en.wikipedia.org/wiki/New_Venture_Gear |

I think you are thinking of the "old" Borg Warner OD units, that were used by many car manufactures back in the '50's, and '60's. They mounted onto the rear of a 3 speed standard shift trans with an adapter plate. Chevy, Ford, and Chrysler (probably others) all used them and they were almost identical to each other.I had several cars with them. Really liked them. I had one car that I put together for towing one of my race cars. 1962 Chevy Convert, 348 engine, with the 3 speed stick on the floor, and the BW overdrive. Had a electric switch on the shifter, to manually control the OD. I could do "split shifts". 1st, 2nd, 2nd od, 3rd, 3rd od. Just like a truck with a 2 speed rear. |
