I drove the car with D1 or D2 to the closest shop. YES got rip off, baster charge me $50.00 to plug the machine to get the code P1753. Tell me it is a transmitting problem. So he look under the hood and saw two wires was bitten out. Charges me $55.00 to connect one of them and said can connect the other one. Once got that wire connected the D4 when back solid and drive normal. What a rip off place $105.00 to connect one wire, because of F*k*ng NYC rat decide to chew my car wire. NEW PARK IN NYC.
