Having a nagging drip from my 64.5-65 4 speed trans leak between the trans and bell housing. Had new seals put in but the drip continues. Starts at the lower bell housing , follows along the housing and drips from the trans drain plug.
Here is a pic of the leak/drip.
Any one else have or seen this issue?
Thanks

Probably the plug for the shift rail on the face of the transmission case, a well known issue. Remove the plug, clean the oil off the case and replace it with a new one with a small bead of sealant around the perimeter. Some have also filled the recess over the plug and troweled it flat. Permatex makes and RTV for use with gear oils, other products will work as well. Make sure the vent in the top plate is not restricted or clogged, or drill and tap the tailhousing for a Stewart vent.

Thanks do you have a drawing or pic of where the shaft plug is located?
Also if one did nothing what is the long term effect other than losing fluid?

the plug has a bolt head and is between 2 shift arms. long term of loosing fluid is a burned up transmission. the leak can also be from a shift cam o-ring

Sorry for more questions would the leak from the plug flow forward or straight down? The drip ends up coming down off the drain plug.
thanks again

Leaks do not flow upwards unless forced by air or slung off a rotating part.

There's another possibility and that's the countershaft bore. This is assuming that when you had it resealed they replaced the input shaft seal and gasket.

Pic below shows the face of a toploader case, silver plug is the shift rail plug. Part number is Dorman 550-006. Hole at 6:30 is the countershaft bore, which typically doesn't leak unless it's worn or the countershaft is out of tolerance. You could remove the tailhousing, push the countershaft back a bit and smear a little sealer in the bore.
