Let me explain quickly....my engine runs great, idles great. the CEL on this video is p0440 and p0171 and are I believe unrelated to my issue.
The transmission shifts smooth but around 50-55mph the rpms jump back and forth between 1,500-1,800 rpms. The car studders someone because of this rpm jumping back and forth. I thought it would be the transmission but it shifts smooth every gear, it literally jumps like this while driving steadily, not while shifting or accelerating.
I was told it is most definitely the torque converter.
