Problem with the speedodometer

Thats pretty tough to answer since, harnesess borrow different feeds off the engine harness for when you accelerate to tell the tcm info from the tps sensor....another sensor it reads from is the brake sensor to tell the tcm when to tell the trans to downshift. You really need to seek a qualified technition that knows how to mix harnesses... sorry I couldn't helpout more....sounds like an awesome project. Call a an auto wire harness maker with your info and have them custom make you a harness...

a few... either wheel speed sensor or speed cord to trans is broken

1. No it will not work

The sensor is usually located at the passenger side axel near the wheel drum. It works by sending a signal to the PCM at the exact velocity. I think it is the sensor.

This model car should have a speed sensore on the trans. The wires go from their to the back of the speedodometer. 99% of the time its the speed sensore.

Drivers side rear of the transmission at the tail shaft. If it's a manual trans it will screw in and it auto it will have a metal tab with a bolt holding it in place.

Would be nice if you listed the trans and model!
2WD man@ 600-800 Auto 3@ 550-750

4WD man@ 700-900 Auto 3@ 550-750

With auto trans selector in "D" position

there is a speed sensor on the top of the rear differential. either the sensor is bad or it has become unplugged. when the truck doesnt know how fast it is going, the trans goes into "limp mode" to protect itself...whic causes it to shift hard and if u look you'll notice the o/d light is blinking

how do you remave a starter from a chevy s-10

Check your CPU. Might need to be replaced.
