Transmission codes P0716(TSS) P1618(generic CEL) Topic is solved

I'm not familiar with either of these codes and where to start looking. Haven't had any issues with the transmission until today. Dash lit up like a Christmas tree but, the transmission is still working. I checked the codes and cleared them but, not sure where I should be checking connections. I did get hit last week on the front passenger side by someone changing lanes so maybe it jostled the modules loose?

As I understand it, the P1618 code is just a code saying that the TCM asked the ECM to trigger the CEL.

Appreciate the advice. Not sure why they are showing up sideways but, here are pics of the readings.

I just found this, looks like it's the transmission speed sensor or what Volvo calls a 'vehicle speed sensor'.
