Please help me understand the codes my car came up with.

What is your question?

My car has 161316 miles on it (!) and has been a great car ever since I got it used 3 years ago! It's been a bit sluggish lately and just isn't getting the mileage it used to get. And it's been acting a bit strange. So I took it to a local mechanic and had the codes read. Here it goes: VIN # JHMCN36585C003848 CK Trans Operation Advise- -Trans Indicator Light Flashing Codes--Trans Module:P0722 Output Shaft (Countershaft) Speed Sensor No Signal, P1717 Reverse No Position, U1260 ATFP Control TCM/PCM Comm Failure. IMA Code: P1575 Motor Power Inverter (MPI) Module Voltage Malfunction, P0700 A/T System Malfunction, PAOC4 Ybrid PCM Requested MIL Light--ABS Codes 61-1 BAT Voltage Low. 83-1 ECM Relation Failure, AIR Bag 61-10 Open LF Seat Belt Buckle Switch. I have an AUL Extended Warranty (Estate Coverage) that expires at the end of next month, and it is my hope that if I fight hard enough I WILL get this fix covered under my insurance... Help me get knowledgeable on all this please!
