A: The transmission vacuum modulator valve determines how much load is on the engine so the transmission can shift properly. It has a vacuum line that connects to the intake and measures the amount of vacuum in the engine. Remove the vacuum hose from the modulator. Using a small screwdriver, turn the screw inside the modulator. Vacuum should measure 13-17 at the modulator idling hot in drive brakes applied. It may take several tries to get it right.

A: Is the fluid transmission fluid? (Transmission fluid has a distinctive odor.) Is the vehicle not shifting properly? If both answers are, "Yes", this is likely the part that is leaking and needs replaced. If I remember correctly the transmission vacuum modulator is the only round part attached to the transmission on that side other than a couple of lines a few inches above it, but without looking at it I can't say for sure.
