04 silverado problems with Bully dog
I have an 04 Silverado with a Bully Dog on it for 3 years now. My tuner went into recovery mode and shortly after truck started shifting odd. My RPMs would fluctuate up and down and up and downshift for no reason. Now It won't shift out of 2nd gear. I teied to uninstall the tuner but could not do it because of a 358 code. Would flashing my ECM fix this problem? Bully Dog wants me to send my computer and tuner and they will flash it and install my tuner for no charge. Can a faulty Bully Dog cause these problem?
