1996 Jeep Grand Cherokee Limited transmission not engaging in gears

I have a 1996 Jeep grand Cherokee limited v8 with an AW4 transmission. Before it stopped engaging in drive, it started grabbing as it was braking and now when I start it, it will engage in reverse and drive for a few minutes while cold. However once it warms up, it will NOT engage in drive (3, 2, or 1) anymore, it acts like it is in neutral. It DOES engage into reverse and makes a very loud grinding/whining noise, but will move. When warmed up it also sometimes grinds in neutral.. I have been researching and found out that I can unplug the TCU/PCM/TCM (can’t figure out which one I have) and it should shift manually but I am stuck on what type I have and where I can find it on the vehicle. Is this where I should be starting to diagnose this issue? Any help trying to diagnose this would be so helpful and much appreciated.

Hi, Mackay, welcome to the forum.

But, uh, you are in the wrong place. You have a Grand Cherokee, and this section is for the Cherokee. Similar in a lot of ways, but different enough to warrant separate sections.

Yours is over here.
