i have a 1997 chevy tahoe 4wheel drive and my abs light turns on but at the same time mytransmission won’t engage to the next gear and also my speeddomter is not how fast i’m going it does this for a few mins than its stop
Does the Check Engine light go on? Is it on now? I suspect a ba Vehicle Speed Sensor (VSS). It would affect the ABS, transmission and speedometer this way. The ECM should have set a trouble code for this.
