So I recently replaced the vacuum modulator on my 1965 mustang coupe (260/auto/c4). I also replaced the vacuum tubing that runs from the engine to the modulator itself. After this replacement I took it for a test drive and the shifting was immensely better. The next day the car was taken on a short drive to church (4 miles there and back), and began leaking trans fluid. I wasn’t driving it when this happened and when I returned home there was trans fluid all underneath the car, on the steering linkage, trans itself, and even in the engine bay on the inside of the hood back by the brake master cylinder. Not to mention, a Massive trail leading right back to my house on the neighborhood streets (Which I’m sure my neighbors will love me for . I think the leak is coming from the modulator (perhaps I simply didn’t tighten it enough), but that doesn’t explain the excess of fluid on the rest of the car. Especially given the fact that the bulk of the mess is located in front of the modulator so I don’t understand how it could have gotten there. Any suggestions? How should I go about trouble shooting without painting the rest of my neighborhood? Thanks! Happy thanksgiving!
