Ok, NEITHER of the manuals that I have tell how/where to access the shift linkage adjust for the automatic wagon...

 

I just got a 86 auto wagon with pushbutton 1 range 4WD, and the tranny is in Park when the shifter is sitting in reverse.....

 

HELP! I need to get this adjusted....

Look under the trans, on the driver's side of the trans pan. You should see a metal rod going up into the console, it runs through a little lever sticking out of the trans. On the end is about 2-3 inches of threaded area (total, that includes the covered part) with a nut on the end. Loosening or tightening this nut will adjust your shift linkage.
