Still wondering if it’s the spark plugs and would a misfire cause it to change gear weird at high rpm?

Is the CEL on and if so are there any misfire error codes?
A more transitory misfire condition can have the CEL flashing and the CEL might not remain on after the misfires have stopped.
I have encountered -- 2nd hand -- issues arising from the wrong plugs being used in engines. Just because a plug compatibility chart shows Plug X is the same as a factory plug is no guarantee this is truly the case.
You should first confirm the gaps are correct before installing new plugs.
Instead of misfires are you perhaps inadvertently/unknowingly hitting the rev limiter?
