Gear indicator issue

Hello,

I have a 2007.5 6.7 Cummins. The truck is deleted with a minimaxx tuner. (No trans tune) s&b filter, arp studs. The transmission was repaired not so long ago possibly 1000 miles ago.

My issue is that the transmission shifts perfectly, the “manual shifting” works great and the over drive as well. The only issue is that the shift indicator is off. The whole top indicator doesn’t light up. The miles are working fine. Everything else in the cluster works great.

Just need help on how to tackle it. Did the diagnostic test for the cluster and test came up good.

Maybe I just need to replace the cluster ?
