Hopefully it's a simple fix.

Take the 2 bolts out that hold the shifter and lift the retainer and the shifter out together. CAUTION: There are 2 springs under the retainer - -- DO NOT LET THESE FALL INTO THE TRANSMISSION!
Look into the tranny through the hole and notice the 2 rails that run from the front to the back. There is a notch in each of these rails...with a huge screwdriver or pry bar line up the notches side by side, reinstall the shifter into the notch, CAREFULLY put your springs in and bolt it down.

About a 2 beer job!

Good luck.

How have the temperatures been lately?? Freezing?? My Super 88 had same problem a few weeks ago, was near zero at night and about 25 when I started it, moved over to wood pile, hooked up hydraulics to splitter and worked it for 45 minutes, everything warmed up and shifter worked, I figure condensation froze the little poppet ball for the center shift rail. Works fine now...

Sometimes the pressed steel rails in the tranny get a little too wide.
