Trans leaking out of tail shaft.

[Fran Blacker]

If you jacked the front of car drive shaft yoke would have fluid in it.

I just ran into this . I know I have a bad front seal. I'm in the process of dropping the tanny , I pull the drive line out and i'm getting fluid leaking out of the tail shaft
the hallow shaft of the drive line that goes into the tail was full of fluid. Could the leak from the front seal work its way back. Tail had not been leaking until I pulled.
this is a fairly fresh build

It would pass trough the rear seal ? and yes the car has been jacked up

There's no seal where the tail housing&main case are, just the paper gskt where they mate up. Yup jacking it up will let fluid slosh back there. I would think the only way to have a leak at d/shaft would be the shaft seal or a plugged vent at front letting to much pressure to build up.
