[QUOTE="pirate air, post: 15094, member: 27"] This is correct. The transmission problem should be PCM. The PCM and BCM communicate between themselves (along with a bunch of other modules) via CANbus, the BCM does do things that affect the power train, but the PCM makes the actual adjustment. For instance, your cruising along and you turn on your A/C. When you push the button on your HVAC (Heating, ventilation, Air Conditioning) head, it sends a signal to the BCM. The BCM tells the PCM that the A/C is turned on. The PCM takes note and adjust things like the engine idle RPM and cooling fan speed. [/QUOTE]
