I bought a 2000 Sonoma a month ago. Today on the freeway running about 70 the Service Engine Soon light came on, a few minutes later it downshifted to 3rd. Fearing the worst I got off the freeway and took side streets the rest of the way home. It ran ok, shifting was okay, just wouldn't go to 4th.
have the same problem?
