6r80 transmission oss code p0721 p0722. aftermarket replacement. Napa part number. 926-0149-1

I'm only pointing out the $200 part from napa.
Also, wolf's head transmission fluid has the same additive according to the napa parts store clerk. I did use mercon as suggested by fordtechmakuloco.

So this solved p0721 which reads for speed sensor range?
