F'n Tranny

Tranny ran fine for days. (AUTOMATIC RO)Then today when i was going to back it into my driveway, it would’nt go into reverse. So I had to put it half way into park for it to engage. NOW, the freaking parking pin won’t engage. Any suggestions? only has about 38k on the tranny. This fu*kin sucks. Just shelled out $300 for the damn thing to pass smog. Now this. Please help, desperate.

I realize this is an old post but as of yesterday I now have this same problem. What did you do to fix this? I have done a lot of work to the car to pass vehicle emissions and now this happens which will make my car fail. Any help would greatly be appreciated.
