Okay, so I bought this car not even a week ago and it has been driving okay. Until last night. It loses a lot of power and is now pulling codes u0101 says lost communication with TCM and code u0100 lost communication with ECM/PCM A. U0155. I'm not sure if it's at all related but the gear shifter has been getting stuck sometimes as well. I'm not sure what needs to be addressed here or replaced to fix problem, but it's driving really bad and I hope it's not a big deal. Opinions on cause if this appreciated. Thanks
