pulled the drive back, cable still attached, removed cover, the other end of the link tha attaches to the shift cam was broken off, had just worn down over the years, drilled it out and installed a ground down headed bolt with locktite, works great now ! thanks Rob

I have the same issue - going to pull the drive on Sunday. Any pics or part numbers?
thanks!

No, sorry was trying to beat rain we were supposed to get, but after pulling the rear cover it was obvious....now getting a bolt in place of the pin...well took grinding....Rob

Glad to hear you found it and it wasnt a disaster!
