It could be as simple as a a leaking drain plug or as complex as an output shaft seal. The usual diagnosis is to clean the area then spray on some tracing powder. Around here, $166 would get about 1.5 hours labor. I would want to know exactly what that money covers. Flimsy diagnostic procedure can create a black hole for money.

In the meantime, check the ATF level. The leak itself won't affect the transmission, but if the level goes too low it will cause problems.
