I have been experiencing problems when I tow a trailer. At low acceleration speeds (just below 2K on tack) the BATT light appears in the "message center". When the transmission down shifts and the RPM's increase the light goes out. When I use tow/haul the transmission inconsistently will not down shift to accelerate, or some time will not release the higher gear even after it's no longer needed. I have read this might be a result of a faulty PCM (power control module). The service engine soon light will some time come on, but eventually go out. If you think it is the PCM, approximately how expensive a fix do you think it would be? What are your thoughts? This is my first experience with this site.
have the same problem?
