Question about 1997 Chevrolet K1500
Drive truck willnot shift from 2nd to get to third code reader says 1st adn 2nd shift error replace 1-2-2-3 shift solenoid still will not shift
Shift error codes are enabled not only if the solonoids are faulty, does your scanner show you the solonoids switching? you could have a wiring fault. It could also be the pcm not allowing the solonoids to activate. These complicated systems are very difficult to diagnose for us profesionals with all the scanners and machines we have. Find a transmission shop in your area with a system to drive the vehicle bypassing the computor system, this will determine electrical or internal trans failure. But before you do anything check your conections from the transmission to the pcm. Also all the engine conectors and earth straps.
