streetdemon Posted March 3, 2023 Report Share Posted March 3, 2023 (edited) I recently started leaking oil between my transmission and the bell housing. I ordered a gasket kit but there was no input shaft seal and I want to make sure I have all the parts before I tear into it. The only schematic breakdown of parts I could find doesn’t show a seal. I am certain that there has to be some sort of packing or rubber seal for the input shaft. Has anyone resealed their transmission and know how I can find the seal I need or what to do? The gasket set I have is NOS and it is all flat paper style gaskets. thanks, Brad Edited March 3, 2023 by streetdemon Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted March 3, 2023 Report Share Posted March 3, 2023 The 3 speed uses no input shaft seal. Quote Link to comment Share on other sites More sharing options...
Sniper Posted March 3, 2023 Report Share Posted March 3, 2023 There is no seal there. This has been covered several times, once fairly recently. I put together a fairly complete reseal listing for all seals and gaskets on a 51 Plymouth three speed.

Young Ed Posted March 3, 2023 Report Share Posted March 3, 2023 This is a leak I've been fighting on my 48 equiped with a 52 overdrive. Next time I mess with it it's getting a nickel pushed into the shift rail. Quote Link to comment Share on other sites More sharing options...
streetdemon Posted March 3, 2023 Author Report Share Posted March 3, 2023 What is the best manual or source for schematics for the manual 3-speed? I bought this one a couple years ago and it has zero information about the manual transmission. I have tried searching the site but I can only find bits and pieces, I like to get a copy if I can.

Jonathan Posted April 13, 2023 Report Share Posted April 13, 2023 Working on my 1950 Plymouth p-19 manual transmission and am chasing down leaks. I believe I need the seals for the Lower Gearshift Selector Lever & the Gearshift Lever Shaft. (See the attached picture where I outlined the seal designations in red.) Looking elsewhere on the forum it seems to me as if the Lower seal is either the Clearwater Hydraulics #2-111Q or the McMaster Carr 90025K224. Is this correct? I couldn't find any info on the seal for the Gearshift Lever Shaft. Thanks. Quote Link to comment Share on other sites More sharing options...

Mine starts on page 205 for transmission info. Quote Link to comment Share on other sites More sharing options...
