I have read that some of the 5 series JDs get water in the shifter boot which freezes and prevents shifting. Some have taken the plate off the bottom and drilled drainage holes to prevent it. Here's a link to some discussion about it:

Hi all,
I figured I would join since I have been using the site for research. Lots and lots of info here! I am waiting for my new-to-me 2012 JD 2320 to arrive this weekend. It feels like Christmas in February.
I also have a 1985 318, a 1952 MC and a 1974 IH 784 4wd.
Thanks for having me...
