It never ends. Leaky selector shaft seal.

Your problem looks like the lingage is flexing the shaft. Just look at the picture and you can see the shift linkage and the throttle pressure leavers are binding. I'll bet if you take the levers off the leak will stop.. Had one come here that was leaking. The lokar throttle pressure wasn't install properly.

I think it looks like that just from the angle I was able to take the picture, kinda looks like the kickdown lever is riding on top of the shifter cable, but I assure you that it's just an optional illusion. There is plenty of clearance between the two and they both move freely without any binding between the two.
