Transmission juice flowing out of front, what am I going to find?

[Slickster]

48 P15, new to me, transmission was empty, filled it, lots of juice runs out of it after driving....will pull trans out, what will I find, front seal or what?....want to have parts on hand instead of tearing it down then have it all sit around...thanks

[Slickster]

Just did some light reading after searching, will have gasket set, check retainer to see if it needs a groove, and replace trans to bellhousing gasket....more dirty fun....

There is a gasket that installs between the front of the trans and the bell housing. This seals the holes the gear shafts mount in.  The other likely spots are the output shaft seal and the speedometer cable.

A regasket kit for the whole trans is cheap, Andy Bernbaum's sells them and the rear seal. 

 

I seem to remember there was a thread on this site regarding leaks from the input bearing retainer.

 

Here it is

While replacing the rear motor mounts,  a piece of paper gasket fell down into the mess of crud I was scraping....clue maybe?

What drivetrain system does your car have? Dry clutch and manual three speed? Or Fluid drive?

[Plymouthy Adams]

if this is for your listed car in profile you will need the gasket between the front of the tranny and the bell housing

Got it thanks, 3 on the tree.....

The front bearing has no seal.  Instead, there is a drain back passageway between the front bearing retainer ( this is the funnel shaped piece that supports the throw out bearing)  and the main case.  I am betting this drain is blocked by a carelessly placed gasket.   I spent 4 1/2 hours this past Labor Day repairing this very thing !   4 1/2 hours to replace  a 25 cent gasket !   Fixed the leak though !       I am not going to reveal who assembled the transmission but thankfully it was not me.

And be sure the retainer gets modified if necessary so it will drain properly:

Pulled transmission, half the gasket was gone, cleaned it up, made a gasket, sea!ed it up, no leaks now...thanks you all....

When I next replace the front bearing , I will use one that is sealed on the front side.  this should reduce flow through.

I talk about the 1-side sealed tranny input pinion bearing here. Part number shown fits my '38 Ply.
