There really hasn't been a change in the reservoir level which I would have expected...maybe a very very little??? Clutch still operates fine. Going to drive it to work tomorrow and see how it goes. Extra bottle of brake fluid in the back just in case.
When you replace a leaking master cylinder, the new master cylinder starts producing higher pressures, so it's not all that surprising that the an old slave cylinder would react to the higher by leaking. On cars with an external slave cylinder you might as well replace it when you replace the master. On cars with an internal slave cylinder, and where it is a large amount of labor to pull the transmission, you replace the master cylinder and pray for the best.

In your case I'm guessing you need the slave cylinder replaced. If the leak is not bad then you may be able to drive on it for a while. In the mean time start saving your pennies for repairs. If you are not doing it yourself, start finding transmission shops you can trust and get quotes. When you pull the transmission you'll want to replace everything in there that is replaceable.

Good luck.
