Leaking 1940 Ford Transmission
I am trying to help my father solve a problem with his 1940 Ford Coupe. He told me that transmission is leaking and it is a well know problem with this transmission. Any help would be appreciated.
It is leaking from the rear.

Yes it would help if we knew where the leak was since we cannot see it.

1940 Fords are 66 years old now ...
And they leak ... and then ... leak some more ...

I drove this one for many years ... until 2005 ... when I sold it ...
I rebuilt the transmission and it still leaked ... less to be sure ... but it still leaked ...

I have been told they leaked NEW ... :(
I put new shift seals and a new side cover gasket on mine and it slowed the leak way down ... but it was NOT the best seal area on the shift lever seal areas ... they were just worn ... 60 plus years will do that :D

1939 Ford transmissions leak WAY less ... because they are a top shift ... and the 40 is a side shift ...

1939 Top shift

1940 Ford style side shift ...

Most V8 Ford parts suppliers have this kit ...
About $60 ...
This should Slow down or fix the leaks ...
