My girlfriend has a 1999 Ford Taurus that is leaking transmission fluid. She had someone take a look at it for her and was told her front pump seal needs to be replaced. Is there anything we can do to stp this leak short of putting it in the shop as she can't do it right now. Is there something that we might be able to add to her transmission fluid that could possibly seal it from the inside for a while until such time as she can put it in the shop to get it replaced? Any answers will be highly appreciated.
