fitting leak
i noticed that a small fitting on the drivers side of my TH400 transmission is leaking. it has a hose coming out of it that runs toward the engine. Any idea what this fitting does and what fixing the leak involves?

It took me a while to figure out that the "hose" you refer to is actually the speedometer cable. Follow it to the other end and you'll find it actually passes through the firewall (unless you have cruise control, in which case it will run to a transducer on the inner fender panel). There are two O-ring seals here, one between the housing and the trans case and one internal to the housing that seals the speedo drive gear. Both are easy to replace.
