Auto shifter problems

[Michael J Myers <mimyers@prairie.NoDak.edu>]

I have a problem with the shifter on an '86 5K.  This is with an 
automatic.  Couple of days ago, I believe that some water got into the 
shift cable and froze up.  You can force it into gear with quite a bit of 
muscle.  After about 15 minutes of driving around, the shifter will move 
with no problem.  Anyone know how hard it is to replace this?  Is this a 
common problem (ie no problems with a junkyard cable) or should I replace 
it with a new part?

Thanks
