Our 1997 Grand Caravan with 170K has transmission fluid seeping from the outer seal where the left driveshaft connects to the transaxle. Is there a stop leak liquid that can be added to the transmission fluid safely? Is replacing the seal a major expense? Thanks
It’s wiser to have the halfshaft removed and replace the seal. Should cost less than replacing the halfshaft as seal costs a lot less than a new halfshaft.

Nothing short of a new seal will stop that leak. If the axleshaft is in bad shape, now’s the time to replace it.
