Sounds like a speed sensor. They are on the transmission. There are usually two of them a primary and a secondary. They are not too hard to replace and not very expensive either. They will be towards the end of the transmission and just screw into the transmission. They will also have a two or three wire connector coming out of the end of it. They should be two of the only sensors you can get to without opening the transmission.

1999 Expedition. Why is odometer operation erratic?

Most likely an internal cluster problem. These units are printed circuit boards and anything from solder to a loose transistor can cause problems. The guage assembly will have to be removed and tested/repaired to correct the problem

How do I check the instrument cluster on a 1996 dodge Dakota?

i believe it has a vehicle speed sensor in the rear diff that is probably your problem as the sensor you replaced in the transmission was probably the output shaft speed sensor

The tach, speed odometer and the trans slips bad

It sounds as if the vehicle speed sensor is malfunctioning.

Same prob. Tach and odometer dead. will come on intermittently


I had a similar issue but the issue is not related to connections. There are many steps involved with this, but it is related to two transiters on the circuit board that have overheated the connection for the odometer and the tachometer. To complete this job, I did it with a $17 soder gun and $3 worth of tin solder.

Anyways, I got it to work after this.

You need to unplug the battery, take off the radio panel, the dash, unscrew the speedometer casing from being held on, take off the back, unscrew about 15 screws, unplug the gauges from the computer, then take out the circuit board. There should be two blue transitters very close together and between them, a small nub that has likely worn away. Also on the other side of the board, a browned spot likely exists. Each of the transitters will need new solder.

This link that I followed will fix the issue.
