Yes, check the vacuum line between the transmission and the throttle body. If you can see ANY sign of oil in the vacuum line, the vacuum modulator is leaking. Of course, all of that is dependant upon YOUR transmission having a vacuum modulator. Some do, some don't. Generally, they are quite simple to replace, so long as you keep everything clean.
