OBD port location 2000 Mazda Protege

I have a 1992 Dodge Caravan, column shift that has had a problem with getting stuck in a gear, any gear from time to time and I have always been able to shake it or push it through the rough spot and I would be good for weeks or months. I would some times have to cut it off in drive and set the parking brake and I would wait a day or so and it would more easily go back into "park". Anyway, today I guess I didn't have enough patience and forced it to hard when I shouldn't have and it broke in the column. Now I must obviously address and fix the problem. So here is the thing. I would like input on what may have caused it in the first place, where the linkage really is and where it is most easily accessed from, basically how it all works (I have replaced 3 steering columns in my life and 2 transmissions, and a clutch in various makes of cars). I am just frustrated and would like a little guidance because I dread this. Lastly, what is the thing that likely broke in the column, what might that be and should it or should it not require steering column replacement. Thank you

I Have A 96 Ford Taurus. It Drives Good And Shifts Fine. Except When I Come To A Stop It Will Not Move. I Have To Put It In Park Then Put It In Drive In Order For It To Move. My Boyfriend Changed Out The Fluid N N Filter. Any Ideas On What The Problem Is? Help Greatly Appreciated!!
