Sam Buchanan Posted June 21, 2022 Report Share Posted June 21, 2022 (edited) My '48 P15 is losing tranny fluid in the area of the gearshift housing. It appears any loss would be through the o-rings on the selector shafts and past the housing gasket. At one time I found a source for the gasket and o-rings but can't find that anymore. Anyone have info about resealing the housing and shafts and where these o-rings and gasket can be found? They may be generic--in that case I should be able to source them and can make a housing gasket if necessary (Permatex Ultra-Black?). I use Redline MTF in the tranny and it being synthetic may be aggravating the leakage, but I LOVE how the transmission shifts with that lubricant.

DJK Posted June 22, 2022 Report Share Posted June 22, 2022 On my 52 Cranbrook I used an O ring from the hardware store for the upper shaft. On the side shaft, I sourced an "X" cut o ring from Clearwater Hydraulics (ebay) #2-111/Q SIZE = 7/16 x 5/8 x 3/32. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Sniper Posted June 22, 2022 Report Share Posted June 22, 2022 This is what I came up with for my 51 Cambridge I am going to pull my trans when I swap the 230 in. Thinking ahead I should probably reseal it and clean it up. Nice paint, etc. So with that in mind I am thinking to put together a good reseal kit. Best Gasket sells a gasket kit, no seals. So here's my reseal kit listing Best Gasket 5076 - gaskets NATIONAL 8160S - output shaft seal Speedo adapter seal - Honda 91204-HB3-004 Verify the input retainer groove lines up with the drain. lower shifter shaft seal Clearwater Hydraulics #2-111Q, McMaster Carr 90025K224 Clutch and shifter bushings, any insights there? 1135626 (clutch) What else am I missing? Thanks Oil Seal, Speedometer Drive Pinion (chrome leather, 11/62 I.D. 37/64 in O.D.m .150 in thick) Quote Link to comment Share on other sites More sharing options...

Sniper Posted June 22, 2022 Report Share Posted June 22, 2022 One thing I notice, earlier transmissions use a different part number speedometer pinion seal than my 51. No idea what the difference is though, 652840 - P15 up to 15250253 see thread 1134949 after, see thread Quote Link to comment Share on other sites More sharing options...

Tired iron Posted June 24, 2022 Report Share Posted June 24, 2022 I just did this job this morning. Got my gasket kit from bernbaum, if I remember right. It's too bad these transmissions sit sideways as it makes for much more sealing issues. Quote Link to comment Share on other sites More sharing options...
