Reset speedometer for tire size

Do you have any codes ? Have you modified your steering/suspension in any way ? Have you changed the size of your tires ? If you can share more detail information, this would help

Check your fuse box for a blown fuse. Replace burnt fuse with same type fuse. GOOD LUCK FRIEND.

You need to have someone with a GM factory tech2 scanner go into the computer an change tire size .

have you changed the wheels and tires on you vehicle to aftermarket ones? if so, the chrysler dealer can "relearn" the new tire size that is on you car, adjusting the speedometer accordingly

Different size tires than OEM.

In most cars especially those older models, the speed sensor for the speedometer is located in the transmission. Check for physical wear on the cable that leads from the transmission to the back of the dashboard. If you have increased the size of the tires dramatically, the actual car speed would be slower then the speedometer. Either the components responsible for measuring speed (speed cable, dashboard, speedsensor) is damaged or tire size or transmission parts or the transmission itself was replaced.

Hi, I think 2 things have happened. 1st, when your oil was changed, the technician did not reset the oil life back to 100%. This can be done by turning the key on, without starting the engine, consistantly push the accelerator to the floor fully, 3 times. At the last time, the oil life should reset to 100%. The other issue sounds like a different size tire may have been installed, causing the speedometer to read incorrect. A dealer should be able to reprogram the computer to accept the correct size tire, therefore making the speedometer read correctly. This should not be an issue, unless the current tire size is not accepted in the computer, at this point, you ned to change to the correct size tire, or realize you may be off on the speedometer, and accomodate for your speed accordingly. Good luck...Coop

Is this a 4wd truck? The 4wd optional 15" tire is a 235-60-15, which means that with the tire size you listed, your speedometer will read 3.7% too low (at 60 mph indicated, you're actually going 62.3mph).

Most speedometers are off by a few miles per hour even when new, this is normal
but yours could be caused by putting different size tires on the car check the owners manual for correct size tires

Have you called transmission place? Did they also install it? Ask them if they changed speedometer adapter, and mention the difference in speed.
