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.

Adapt & Overcome

The TCM is responsible for monitoring and controlling transmission operation through the use of various sensors, solenoids, relays, switches, etc. Computer management provides benefits such as precise shift timing, fault detection and increased fuel economy. But a more remarkable feature is the TCM’s ability to compensate for changes in engine performance, vehicle load, driving patterns and physical wear inside the transmission by adapting its control tactics.

The Art of the Silver Bullet

Folklore has it that bullets cast from silver are the most effective means of dispatching werewolves, witches and vampires. Ever have one of those dreams where you conquer the bad guy and save the world? While this is possible in the fantasy realm, silver bullets don’t always provide heroic results in the real world, where many problems need to be solved with brains, not blind luck.
