The Odometer disappears after some minutes on the road and the car speed or gear selection becomes irregular. Like dropping from higher gear to lower gear and vice versa until the odometer comes back on which might take some time. This happens intermittently.

This happens when the instrument cluster shorts out causing the PCM to change gears unexpectedly. to be sure we can do a CAN scan which should pull up a code. you can get a CAN scanner (Controller Area Network) from Amazon from about $32.00.

Here is a video to show you how:

Here is how to change the cluster out which you can get a rebuilt unit for by searching Google or eBay. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
