The other night got in the Suburban started up and check engine light comes on check codes and have five; p0740, p0753, p0758, p0785, and p1860. Truck also seems to be in limp mode ie stuck in 2nd or 3rd gear and will not shift. Checked fuse #20(PRNDL, Auto Transmission, Speedometer, Check Gauges, Tell Tale) and am not getting 12 volts to this fuse. Please Help
