2003 Silverado RPM Fluctuation?
On my 2003 Silverado, my rpms go up about 100-200 rpms and drops back down every few seconds when I’m going around 45-50 mph. It usually happens on flat road. What causes this. It almost feels like the torque converter locking and unlocking. The truck drives very well otherwise.
