Question about 2003 Chevrolet Silverado 2500HD
Hi, either I use the cruise control or not, anytime I drive down the hill or even little slope down the road with driving of minimum of 55mph with or without any loads on truck, the service engine light flashes. It would stop if driving flat or up the slope. Hope you can help, Thanks
It sounds like a transmission electrical problem (possible pressure control solenoid, or trans fluid pressure switch). Unfortunately to be sure you have to have someone scan for stored codes. Although the problem is intermittent there should be "history codes" saved in the PCM. Hope this helps
