UPDATE: Sorry for the delay. I slacked....
Anyway, the old seal was completely dry-rotted. There wasn't much left of it. I had to scrape out the bits with some various picks. Not fun. You kinda have to jam your head up under there to see the top of the shaft and get at the crumbly seal. Small flashlight needed. But, I got it out as best I could and then I looked at the new seal. Imagine a bowl with a hole in the bottom. That's what the new seal looks like. And given that my old seal was toast, I really had no idea what the orientation was supposed to be. So I called Merlin to verify.
According to Merlin, the 'inside of the bowl' goes TOWARDS the trans, while the 'bottom of the bowl' goes towards the Mode Switch. That's what I thought when I looked at it, but I had to verify with Merlin first. The manual is absolutely NO help.
So I got the seal back on and the Mode Switch and shifter connected again. I cleaned up everything and then I jacked up the tranny a bit and removed the cross member. I think the pan is still leaking, so I am going to let her sit for a few days and see if any more drips appear. With the cross member out of the way, I should be able to see exactly where the leak is coming from, but it better not leak at the selector shaft anymore!
