The Tail Housing Bushing is usually what needs replacing.

For what it's worth, in our case, I saw no drips under the car.
But, we had a significant leak at tailhousing bushing.
Happened on our other 245 also, fixed w/bushing replacement.

Someone here should state how to inspect to check the bushing - I'm out of my depth on that.

I suspect it leaks primarily when driving. Makes a mess on car's underside wherever the airflow blows the fluid, but you see little or none on the ground when parked.

The rubber seal is a fairly inexpensive job. However, to really seal the leak (if that'w where it is), the tail housing bushing needs replacing. That takes some time.

Ours was so bad that it fouled the O2 sensor and so caused the "Check Engine" light to come on. Bushing replacement and new O2 sensor cured the "Check Engine" light! We'd had the sensor replaced just a month or two earlier, it died early due to tranny fluid attack.
