p2069 RLEATES to a issue with the trans you will need a code reader to read the trans moduleP1461 does not show anything for me in the system what does the fault code description say?B1360 means you have a failing blower motor regulator. if the fan is coming on at high speed we need to check the signal wire from the Me-sfi module and see if the engine module is activating the fan or if the fan is shorted.
