17521-Oxygen (Lambda) Sensor: B1 S1:Internal Resistance too High: P1113
17539-Oxygen (Lambda) Sensor: B2 S1: Internal Resistance too High: P1131
17585-Bank 2:O2S (Lambda) Correction Behind Catalyst:Control Limit Reached:P1177
18158-Supply Voltage too Low:P1750
From my research it looks like I will need to replace 2 O2 sensors, but Im not sure about the last code? And I have no clue about the tranny code, but everything seems to be shifting ok, so I cleared the code and will see if it pops back up on my drive into work tomorrow.
I found this site on another post on this forum that helped me translate these fault codes and provide a bit more description to problems. Hope this helps. Category:Fault Codes - Ross-Tech Wiki
