The 727 in my 72 demon has marked its territory in my garage and on my driveway with transmission fluid.

After getting her up on ramps, I took a look underneath and it seems to be coming from the inspection cover and the pan gasket. The transmission pan I'm not worried too much about because thats an easy job and its not dripping from there. However its coming out pretty good on the inspection cover.

After doing some searches it looks like the front pump seal and/or bushing could be the culprit. Is it possible to replace these parts with the transmission and engine still in the car, or will I need to drop it? I did a few searches and couldn't find any info on it with the trans in the car still.
