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
I replaced the whole break light and the bulbs too. When I shut the door and then off all the light and lock the door the 3rd break light wont shut off it will stay on till battery dies. I was told to cut yellow wire but that didn't fix it either. What can I do to have a break light and lights when driving but need help them to shut off when I shut off the lights. Where do I locate the problem fuse box under the hood or I was told maybe a fuse or a plug in under the break pedal I have unplugged all of them but it still stays on.
