Bought the truck used, it ran fine for bout a year then transmission starts acting strange. Wouldnt shift out of second gear, troublecode po967, low voltage shift solenoid b. I changed that still no imporovement. Changed ignition switch cuz everyone was saying it had a voltage drop at the switch, still didnt fix it. I found a bad ground wire so i fixed that, kind of improved but now the speedometer doesnt work sometimes and when it isnt working it wont shift out of second gear. But when it is working i have to shift manually for it to work correctly other wise when taking off from a stop it will start off in 3rd gear. Troublecode still only shows p0967. One other thing aotomatic door locks dont work

2014 1500 Silverado. The master power window controls in the drivers door only work for the drivers window. Child lock, door lock and unlock, and driver window works, but window lock doesn't, and neither do any of the other window controls. All the other windows work when controlled by their own controls, but when using the driver door controls, even the OBD II scanner doesn't even detect an input, let alone move the windows. We replaced the controls, only to have the exact same issue. Fuses all seem fine, and there are no codes that come up when scanned. We are truly stumped with this one.

I put a used battery but a good one in it and tried to start it nothing happened at all. I started looking into the fuses. I found several missing one of my boys must have needed some I guess. I don't know if I have found all that is missing and I'm not sure how to find out if ive got them all replaced. So I finally get some dash lights to come on battery light, brake light, and of course the lock down is also on. T… Read complete

Has anybody had an issue with passkey three and found a way to bypass the system successfully? I damaged my theft deterent modul in the steering column 9 months ago. Causing me to lose my business and am now completely out of money. I've also had someone break into the truck and broke the door lock cylinder as well as the ignition lock cylinder. I live 10 miles from the nearest store or business. So walking to work isn't really much of an option for me. I've gotta get thus truck to start ASAP! If you can assist I would be eternally grateful! Thanks.

Replace fob batteries and door lock fuse (50 amp) is good still won’t respond to opening or closing doors with fob
