I'm getting codes for a TCM malfunction (P1779) and P2175 among a few other codes for TPS and IPS. Is it possible they all trace back to one problem? My car has been kind of bucking/shuddering which led me to scan it. And is the TPS on this car built into the TB or separately replaceable? Thanks for any help in advance.

Pry $100 from the junkyard. Or go to the 3.2 part out thread. I'd take it to shop with the right equipment to verify first though.
