'85 CJ7 Speedometer INOP

There could be several possible reasons why your gear is not selecting and your speedometer is not working in your Toyota Corolla 2005. Here are a few possible causes:

1. The gear shift cable may be disconnected or damaged. The gear shift cable connects the gear shift lever to the transmission, so if it is damaged or disconnected, it may cause problems with selecting gears.
2. The transmission itself may be damaged. If the transmission is damaged, it may cause issues with selecting gears and may also affect the operation of the speedometer.
3. The speedometer cable may be damaged or disconnected. The speedometer cable connects the transmission to the speedometer, so if it is damaged or disconnected, it may cause issues with the speedometer.
4. There may be a problem with the vehicle's wiring or electrical system. If there is a problem with the wiring or electrical system, it could cause issues with the gear selection and speedometer.

To accurately diagnose and fix these issues, it will be necessary to have the vehicle inspected by a mechanic. They will be able to perform diagnostic tests and determine the root cause of the problem.

The signal to your speedometer comes from the transmission cover. When they changed the clutch they probably had to unplug the speed sensor.
Hope this helps.

Usually it's the opposite. The speedometer works and the odomater and trip meter go inop. Most likely the speedometer assembly is bad. If the odometer is working you have a signal from the gray and black wire .

Yes your speedometer, and odometer are controlled by your speed sensor.

It may be a faulty speedometer with a short inside, or a short on speedometer wirings or connector.

Whenever car vibration cause the wiring to short, there you lose speedometer and trans functionality.

You need to access the speedometer connector and wirings to
instrument panel to fix this.

Check on your negative groundings
