Okay so after weeks and weeks of research.. and unplugging my transmission speed sensors and plugging them back in again. Also after unplugging my abs ecu. And unplugging the battery. Seemed to fix it for about a week. And then it came back again with no speedo.. and I have no front speed sensors.. so I don’t even know how it determine speed without those two but when I bought the truck it did! I’m so confused and I just need help.
