A Veteran Technician’s Insight
“On these GMT400-era trucks, chasing electrical gremlins can be a nightmare. I’ve seen countless hours wasted on replacing perfectly good sensors. A key diagnostic step is to check all the main ground connectionsโespecially the one near the thermostat housing. But when those grounds are clean and tight and you’re still facing no-communication codes or bizarre shifting, the PCM itself has failed. This VIN-programmed 1997 GM PCM 16229684 is the most reliable fix, saving you time, money, and frustration. It’s the part I’d use in my own bay to get a customer’s truck back to being dependable.”
