Its possible, you never know but highly unlikely on the tranny issue.
There is over 80K on the Century, right? One last suggestion, hows the flow out of the exhaust. Is it consistent with engine rpms?
I worked on a friend's '01 Chevy Impala LS a few months ago with a similar issue. Missing was detected on all cylinders and the 4T65E tranny started acting up. Shifting weirdly especially under load or going up a hill.
No DTCs or SES light.
We found out that the CAT convertor was clogged once the engine was fully warmed up. Evidently it was still letting exhaust flow when cold.
After it was changed out everything went back to normal.
