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

My husband changed the transmission. We got to drive it for an hour or so. Well that night my horn started going crazy. It would honk then go off then again but it sounded like someone was laying on the horn this time. Well I went out there and nobody is near or in the truck. We go to leave the a few hours later and now the truck isn't wanting to start. Please help...
