I'm getting this error code on my wifes PONTIAC G6 with a 3.5L on both the ECM and TCM. I'm pretty sure it's an E67 and T42, but neither one will unlock to let me read the tune. I've tried the auto detect and nothing comes up with that. I just installed the latest upadtes for all of the software. This is with both V7 and V8. I can connect to them with the scan portion and read diagnostic data, but not the actual programming.
