Hi Abe. Thanks for contacting us today. P-0730 is the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission. The ratio of a combination of engine speed and throttle position and the speed of the transmission is used to determine what gear the transmission will use when driving. If there is a problem with any gear within the transmission, then the P-0730 code will appear once this ratio is calculated from the sensor data in the transmission. I would recommend reading this article, which will explain more about this code, what causes it and possible repair solutions.
