Re: Transmission question

It is Packard as they built their own transmissions thru 54 and from about 40 on all are essentially the same inside. The exception is that those used with the 356 engine had a larger diameter input shaft and if an OD was attached, a stronger planetary unit in the OD. Externally they are also similar over the years with the mounting bolt hole locations, the levers for the arms, and the tail shaft or the bolted on OD unit being the main difference.

The basic transmission case is the same but the overall length will vary with tailshaft or OD so there is not a fixed number.

You can check out the training manualhttps://packardinfo.com/xoops/html/downloads/TransmissionAndOverdriveTrainingManual.pdf for details on the unit.
