does the speedometer effect the transmission
Is the TCM working normally and throwing no codes?
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
The speedometer needs to work in a vehicle for safety and informative reasons. The causes of it intermittently working could be the lack of electricity, or a problem with the sensor.Ê
Anything that brings the car to a complete stop? Such as the brakes or a Tree?
The gear between the driveshaft and the transmission is broke you need a knew one
it usually is the gear in the transmission Could be the vehicle speed sensor.
There are multiple reasons for overheating including by not limited to:low coolant levelhead gasket is gonefaulty thermostatradiator is not working properlyfan has failed etc
Cruise will NOT work if the speedometer has a problem
it could be anything. a breaker, a wire, or a battery.
Probably the stepper motor in the cluster. Can be changed but you have to be handy and good at soldering. Stepper motors are available on Ebay.
There are two possible actions: 1) Replace the speedometer head assembly, because that is where your problem is. 2) Ignore the broken odometer and forget about it. The speedometer and odometer are one assembly. The same input that drives the speedo also drives the odometer, so you have a problem in the head itself.
