Leaking A904 front seal

What happens is fluid loss. Dripping begins the within seconds of engine start.
Once about a quart low, there's a fish bite feel in the way it pulls. Also seems to fall out of gear in a turn, especially those exchange ramp circles.
What sux is the leak moving about the unit. My current 904 for example.... First mere seepage was at speedo gear housing. Shortly after that was fixed the selector shaft seal began to leak. About 3 months after that was fixed the front seal started leaking. All the seals and gaskets are the same age ( renewed in 1984 ). Good luck with yours
