P2767 speed sensor “A” circuit

P2767 refers to "B" circuit. Not sure where you are getting "A" for this code. The diagnostic flow chart indicates circuit testing, which would result in the replacement of the transmission revolution sensor, the wiring or connector to the component or the ECM. I would suspect an internal mechanical concern could be possible as well - but if this is the only code, then the circuit is in question, not the measurement obtained. https://repairpal.com/auto-repair-near-me
