Swift 2006 speedometer not working,, but temperature reading or mileage working ..

SOURCE: Replaced rear differential speed sensor

Did you use a mopar sensor.I have fixed this problem many times and not had much luck with the aftermarket sensors.Just a thought.Good Luck!!!

SOURCE: Speedometer works sporadically

It sounds as if liquid got into the instrument cluster and the speedometer gauge might have some rust on the spring. Check to see if any other gauge is sticking sometimes.

SOURCE: Speedometer not registering right speed.

replace a capacitor behind the panel (6.8uF 25V) with the new one.

SOURCE: ABS light & brake light on, problems with speedo working properly

The rear wheel speed sensor is the most common problem on those trucks and will do what you are talking about. It is located at the top of the rear axle in the center. It picks up it's signal from a tone ring on the diff inside! If a tranny input or output sensor is bad then the tranny won't shift properly!

This sounds like it may be due to a bad speed sensor but the best way to find the problem is to have the codes from the engine light read,the computer stores codes that will tell you what has failed, there are many auto part stores that will scan the computer and give you the codes, the code will tell you what has failed, if you can give me the code i could help you better. good day.
