Mazda CX7 Shift Issues with DTC (Component Appearance May Be Deceiving)
A customer arrived at the shop driving a 2007 Mazda CX7 equipped with 2.3L engine and a six-speed automatic. Depending on year, a Mazda CX7 could have several different transmission types from four-speed to six, but this model has an Aisin TF81SC (AW6A-EL).
The customer stated that recently the transmission was acting a bit strange and that the check-engine light would come on as well. The vehicle was taken for a test drive and sure enough a problem existed: erratic shifting. At times though, the unit seemed to work fairly well, which meant at least all of the basics were there.
