Default Re: My 56 Thunderbird transmission Leaks?

Most likely leak points would be: 1) converter-to-impeller housing large o-ring seal cracked, 2) front pump seal worn out, 3) trans pan gasket shot, 4) fluid filler tube-to-pan nut not tight enough.
The last two are the only ones that don't require transmission removal.
I would suspect that if the pan gasket was shot, it might only leak when driving. Same holds true if the park plug in the back of the trans case was blown out.
Also, a leak after sitting (during which the torque converter drains back into the pan) can be from the shift shaft or kickdown lever seals.
