904 Leaking Fluid

I've got a 904 tranny that is leaking fluid. Its wet above the pan on the shift selector side. It started after I put a Hurst quarter stick in. It leaks while its sitting in the garage. There are times after I drive it that Ill put it away for a week and in wont leak a drop, but when it leaks it'll drop an 1/8 quart in a week. The old kick down selector is still there not attached to anything, not sure if I should just remove it all together. I suspect its leaking from around the selector lever. I've already replaced the transmission pan and gasket. Any ideas would be greatly appreciated.
