Got in my 1999 A6 Avant this morning (keep in mind was 10 degrees outside) to go to work, started the car, let it run a few minutes, applied brake and shifter wouldn't budge... let it warm up a little more, but still wouldn't budge.. Never had this happen before. I applied brake and tried one more time applying more pressure harder on the shifter and it moved roughly into reverse, but car didn't engage into gear (info center on gauge cluster still says apply brake, etc. etc.). I pulled down into drive, but nothing either. I feel like I may have forced it too hard and broke a linkage or something mechanically underneath. Although, I'm not familiar enough with the transmission to even know if it has a linkage or what? Tried all gears, even manual shift (triptronic) side.. Nothing.. Car runs awesome and no mechanical issues..
Now no matter what gear the shifter position is in, it's still in park.

It's a 1999 A6 Avant with triptronic.

Any feedback, leads, or ideas how to fix is appreciated!
