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

Passlock kicked in i wired the orange and black and yellow together to get it started. Then replaced key cyclinder and ignition switch but security light stays on when not running it flashes battery light and security light tried the resistor 22000 ohm tween the orange black and yellow did not work tried relearn in process didn’t work not sure where to go now but I want the light out. Is the cyc housing bad ? Do I replace passlock module anyone been in this predicament?
