aunty norm Posted February 14, 2017 Share Posted February 14, 2017 Re: building a 1935 Chrysler overdrive gear box for my 1937 Dodge D5 sedan. The input shaft and 2nd gear need to be replaced! I have found a few input shafts, part number 661300 without overdrive. They look the same as the one I removed! Can these but used? What is the difference between the two shafts? What is the part number of the overdrive shaft? Any help would be appreciated! Does anybody have any that they are willing to part with?

aunty norm Posted February 14, 2017 Author Share Posted February 14, 2017 It could be a 33 / 34 free wheeling overdrive unit? Link to comment Share on other sites More sharing options...

aunty norm Posted February 19, 2017 Author Share Posted February 19, 2017 Thanks for the reply! On further investigation, It appears to be R6 -1 OD and a T86-1P W.G.DIV 11.19.35 box. But I am still after the main drive gear plus 2nd gear. Link to comment Share on other sites More sharing options...

Plyroadking Posted February 20, 2017 Share Posted February 20, 2017 I don't have my R6 unit apart yet to be certain, but on my '39 R7 the transmission internals were the same as the '36 plymouth standard transmission internals. Link to comment Share on other sites More sharing options...
aunty norm Posted February 20, 2017 Author Share Posted February 20, 2017 Thanks for the input! I don,t have a main drive gear to compare with the one I removed! But looking at various photos it does appear to be the same. The only way I can be sure is to take the punt and purchase a new standard one. Then compared the two. When I get it I will let you know!

Just wondering. Did your 39 have the floor shift or column shifter? Link to comment Share on other sites More sharing options...

I was thinking I'd relocate the shifter and rails back till the top was flush with the front of the transmission so it potentially would fit better in my '30 sedan. Got to looking at the difference between the input shafts of the 30 and 39 boxes and decided I'd figure something else out. I came across a 36 R6 and might try that one instead as I like the fully mechanical overdrive better. Link to comment Share on other sites More sharing options...
