Question about Chrysler 300M
P0700 is a generic code for the transmission that there is a signal lost to your Transmission Control Module (TCM) from the transmisison's sensors and shift solenoid. The P0720 is the code for your Vehicle Velocity Sensor ( VVS ). The VVS is the sensor that counts the rotation speed of the out put shaft of the transmission to the axle which in is then calculated in the TCM which will then command the shift solenoid to up shift to the next gear or down shift accordingly to the engine and transmission out put shaft speed. The things to look for is a bad harness connection, wire and then the sensor it self. the sensor is usually located on one of the drive shaft half shafts. It is located on the driver side. If you remove the wheel you might be able to see it. Go from under the car to replace the VVS. You might want to replace the speed sensor and odometer sensor while you are at it. Both are in the same place but one is slightly higher. It takes about 1 hours to locate and replace, but once you know where they are it should take no more than an hour. Good luck and keep me posted, Recap, check the wire harness and clips that connect the wire to the sensor since the problem comes and goes. Keep me posted , be glad to help
