I have seen many posts over the years regarding solenoid code P0757 or similar in asian (mazda) FNR5 Fusion transmissions.
Frequently it seems that folks will retrieve a code such as 0757 (solenoid B stuck open) replace the solenoid and still have the problem. Perhaps they didn't replace the correct one since FORD AND MAZDA IDENTIFY THEM DIFFERENTLY! :shocked:
Ford calls a certain solenoid "B" and Mazda says it is "E" ! Mazda calls one "B", that Ford says is "D". ??????
PAGE 3 of this schematic shows and alerts to the different identities: http://www.transgo.org/Research/TechData/ford-v/FNR5-VB.pdf
This company arbitrarily identifies them in the Mazda format:

Cobra transmission, where I ordered one, sent me what Ford calls "B".
My code reader says solenoid B. I am tempted to believe that my code reader is using Ford data since it is a Ford computer (i would think). Ideally I would replace both, but one is $25, and the other $150 and I don't have the "other" in my hand right now.:tears:
