should be able to replace gasket/o-ring onca speedo gear is pulled if it is an automatic trans
There are several things you can do to repair your speedometer. You can replace the speedometer cable. You can replace the speed sensor in the transmission.
First check the speedometer cable going into the top of the transmission. If it is not broken the instrument cluster must be replaced.
Need to know the price on a 1976 el camino
A 1995 Jeep Grand Cherokee does "NOT" have a speedometer cable. It has an electronic speedometer with a built in motherboard. It receives its signsls from sensors on the transmission and the transfer case.
A 1994 Plymouth Sundance/Duster does not use a speedometer cable. Instead, it uses a Speed Sensor located on the transmission.
check the vss located on the tailshaft of the transmission for the speedometer issue the odometer is figured out based on the speedometer also so it will quit as well. this sounds like either the sensor is bad or a short in the wire from it The cord for the speedometer came undone from the transmission or the gauge cluster is bad
If both the speedometer and the odometer do not work I would suspect the VSS (Vehicle Speed Sensor) located on the tail shaft of the transmission is at fault. If only the speedometer doesn't work it's probably a problem with the dash cluster.
In a 1996 Ford Festiva, the speedo cable is typically located in the engine compartment, connecting the transmission to the speedometer in the dashboard. You can trace it from the transmission, where it screws into the speedometer drive, up to the back of the speedometer gauge. If you're having difficulties locating it, consulting the vehicle's repair manual can provide specific diagrams and details.
if it's the speedometer cable you just unhook the cable from in back of the speedometer head in the dash by unscrewing it and taking it off and on the transmission it also unscrews and then just pull the complete cable out and replace with a new cable.
Alot of newer cars have a red cap on top of the transmission and you have to pull the speedometer on the transmission ( not a due it yourself check if you have a cap on top of your transmission refer to a repair shop or local oil change store.
If your odometer/speedometer stopped working, then you must replace the "vehicle speed sensor" located on top of the differential if your have a manual transmission.
I'd suggest you take the car to a speedometer repair specialist. They can remove, repair and calibrate the spedometer.
