No radical behavior difference (YET), though driving at lower RPM seems to "pulse" a bit more than usual.
Codes do not disappear with ECU code re-set (Cobb), but do not cause a SES symbol on the display.
There is a new display error icon on the top right of my display above the heat gauge that I've never seen before; obviously transmission related. It looks like a partial transmission with 2 "legs," one of which is a broken line, the other one is a solid line to what appears to be the wheels.
Again, the code is P0872...Cobb shows it TWICE, but P0873 doesn't appear, or any other code.
My look-up of this shows: TFP SENSOR/SW C CIRC
Just now, I went back out after parking the car...the codes are still there but the icon is gone.
