Dynaflow leak

[Robert Reppert]

My 1951 special dynaflow leaks somewhere by the tail it starts to leak when she starts up and stops after she sits off for about 3 min. I suspect the torque ball butI am not sure.

Hi Robert,

yes, torque ball is the most likely source for leakage at the rear of an Dynaflow.
These torque balls seem to have a mind of their own. After highway driving with oil hot and thin they keep tight and after sitting for month in a cold garage afterwards with the oil being thickened by the cold you can find a puddle...
You will never know without determining the source. Wash the transmission with brake cleaner as good as possible, start the engine and look where the oil comes from.
As I said: Torque ball is likely, but since it is quite a job to get the transmission out there you probably wanna be sure you do not have to look for another seal also.:waving:

I have heard if there is a torq ball seal leak it may have let oil into the rear end so you might want to check oil level in the differential, not good for it.
