TSS and OSS replacement

[AJRoo]

Today I changed out my TSS and OSS sensors in the transmission. When I was done I noticed that the rpms were fluttering up and down about 200rpm. I gently drove about 10 minutes back home and had some sporadic shifts. By that I mean there was a few rough shifts, some that would have rpm hang, and some that just felt like the transmission couldn’t figure out what to do. Anyone have any ideas as to what could be causing this?

AJRoo, Did you disconnect the battery before/during this repair?

[AJRoo]

Yes. I did the “wire with alligator clips” tip to reset the PCM which helped a bit but I’m still getting rev flutter when braking which wasn’t there before.
