So... from the Code Guide, pg 78
260F “Sensor Supply Voltage”
Overvoltage.
a. The alternator or voltage regulator is faulty.
b. Test charging system.
Did you charge the battery in place before replacing it? Automatic chargers sometimes put out over 16 volts if they try to recondition the battery... if you turned the key on while the voltage was up this may have set the fault.
In your place I’d do a full clearing of codes (using your AP200) from both the engine and transmission, then see what returns.
