G'day miller91,
![]() But sorry I can't help with the mainshaft, although there must be someone here who has a spare they'd be willing to part with? Or maybe the Flackmaster, '37 parts Guru, will see this post and respond? And if, by the merest of chances, you have a Packard to wrap around the trans I invite you to include it in the Packard Owner's Registry!

35-37 Six and 120 trans are identical, everything interchanges. 38-up virtually nothing does

The 1935 to 1938 Six and 120 trans. are the same. The 1939 trans. was redesigned to handle the power of the 320 super 8 which was used in the 120 body in 39, and the new 356 coming in 1940...

Thanks for the responses and welcome.
The site is terrific, as I downloaded all the service manuals and tech bulletins regarding this transmission. I suppose in the end I can see if the mainshaft core is viable to be reconditioned, of course I peruse eBay to see if I can get lucky. Hoping to avoid the 650 expenditure from Kanter or Max Merritt, but if I have to pony up I will. So far things are cleaning up nicely, but boy, what is up with the universal joint nut? I know Packard made a special thin wall socket to get these off, what a pain in the you-know-what! Can you adapt a modern u-joint carrier to these boxes? Jeez...

Not all parts interchange between 115s and 120 for 1937 for sure. The 115 cane was painted whereas the 120 was chromed. I have 7 of those. 35-38 trannys and have some mainshafts removed. PM me if interested.

1936 and 1937 120's Are what we like best. But we also like all other Packards too.

Correction- The Packard parts book gives one part number for transmission assembly from '35 120 through '38 16th series six and 120/Eight. All parts interchange from '35-'38 with the exception of the shifter cane but not because there is a difference in finish. From what I see it is the relationship of the dash, seat and cane that may require a different cane.
As a unit without the cane all '35-'38's interchange.

I sacrificed a box end wrench for that universal nut. I ground it down thinner to fit in there.

Quote:
Tight clearance on the flange nut indicates a transmission from a 6 cylinder car which used a smaller u-joint than the 8 cylinder models. Outside width of the flange is approximately 3-1/4" for the 6 and 3-3/4" for the 8.

Yeah what a pain the ass! Maybe I'll look for an 8 flange...what a bear to get off.
