Question type: Maintenance & Repair
I have replaced the ECM and speed sensor on tail
of transmission and brake light switch. When the
brake light is on the truck has no speedometer and
wont shift out of first gear. When the light is out the
truck runs and drives perfect. I'm running out of
ideas tired to read codes by jumping A an H with
no luck did not work or do anything.

You've got a wiring issue with that citcuit. Seems intermittent, easy thing to try is to replace the connector for the speed sensor on the trans. After that it'll be difficult

Misread your answer back ur saying try the connection to the speed sensor got ya

Thanks, I have noticed sometimes jiggling the wires did make the problem go away. I figured it was a lose wire. I try to pin point it by checking the fuse box. Which fuse box was it? Was it the one under the dash by the brake pedal?
Driver side on the dash remove panel to make visible
