The stock AOD in my 93 GT has been increasingly difficult to shift thru the gear selections lately. Going from Park to OD, OD to reverse etc, etc takes a significant amount of force exerted to my shifter. When this problem developed, I also noticed that my selector would not guide into the "Drive" selection, so I have been keeping it in "OD" like I usually do anyways. The problem has since quickly progressed to where I am now unable to select any positions, as it is stuck, and unable to guide into any shift positions. I was pulling into my garage which is on a slight incline (which is when I experiance even more difficulty shifting) where I pulled in, yanked it into reverse, then slammed it back into OD (all with significant force to shift) and when I stopped I tried to put it in Park, but it would not go. I had to cut the ignition off while I was in OD as its impossible to get it into Park now. Afterward I tried jacking up the rear of the car (and after that the front also) to offset any incline/decline issues that may cause it but no luck, still wont guide thru the gears. I also used a whole can of WD40 spraying the tranny linkage and all the parts under where my shifter is, but still no resolve. After about half an hours worth fustration and anger I finally forced it into "park" (so that I can at least release my keys from being stuck in the ignition) on the shift "selector", but I do not believe that the tranny is actually "engaged" into park as it just now all of a sudden rolls back and forth as if it is in neutral. I have always had stick cars in the past, with this being my first auto trans, and I am completely unaware of any any quick fixes or what the issue may be. If anyone has any suggestions whatsoever I would greatly appreciate the help. Thank you very much in advance to all suggestions and/or advice.
 
It is relatively easy to jack the car and get under it to see what is the problem.

Disconnect the linkage or cable at the trans lever, and see if it shifts easily by hand. That will tell if it is an internal prob, or just the shift lever mechanism or cable.

A broken trans mount of engine mount can also bind the shift linkage, so check those also.
