Dodge Instrument Cluster Light Issue

Dodge RAM 2500 4x4

2003 dodge ram 2500 5.9 cummins and only the park and neutral shift indicator lights will light up not the drive or reverse first or second gear.



Troubleshooting Solutions For This Problem:

As per problem described it's possible that the instrument cluster itself could be causing this but that's not very likely.There are other possibilities too.

Faulty Range Sensor:

Most likely the problem is with the range sensor in some way. The range sensor is on the left side of the trans and is what reports shifter position. It has a plunger that contacts a piece on the valve body rooster comb an varies a reference voltage based on shifter position. A bad range sensor or sensor wiring issue will cause your problem.

Broken Range Sensor Guide
On the rooster comb where the range sensor contacts there is a plastic guide. If this guide is damaged or broken off then it will also cause your problem.

Getting this possibilities checked will help.
Thanks.
