Allison transmission problem: While in overdrive with a towing load going uphill, the transmission will downshift in or out of cruise control, causing the engine to increase speed up to the danger zone of 3300rpm. The vehicle was checked by the listed dealer, whom noted that General Motors has no correction available for the downshifting and engine racing in overdrive. This complaint is to register this observation with my vehicle.
