Replaced both sensors on transmission and still nothing. I have tried 3 different clusters but no luck. Any ideas?

Hi,

The speedometer function is based on different options on the vehicle. For example, if your vehicle has anti-lock brakes, the signal comes from the ABS module. If it has a CVT transmission, it comes from the transmission control module (TCM). If it doesn't have a CVT transmission or ABS, then it comes from the output speed sensor on the transmission. (see pic below)

So, I need to know which design you have.

Also, I need to know if you have scanned the can-bus. CAN stands for controller area network.

Here is a link showing how it's done:

Let me know.

take care,
