I’m sure I changed the correct one. (#11) I’d did also change #18 thinking that may be an issue.
I reset the codes but still get them. Pcu 14 comes on every time I try to shift from 13th to 14th or 3rd to 4th reverse.
My pcu address always reads 000 clutch up or down.
I will try to jump a wire to see if it changes to 001.
