Usually it means "No data communication / no power to transmission".
I'd have it checked out soon. My team truck just did this 3 weeks ago, turned out to be a fried voltage doubler and brain. $6500 to repair just those two electronic bits, on a million miler, so I said naw, and had the shop convert and swap in a 13 spd. Fuller manual. Picking the truck up tomorrow.
Gonna be about 11 grand or so with a reman 13, used flywheel, used pedal, linkage, new cross shaft, new clutch, few other things. Plus they fixed a leaky rear structure while the trans was off.
Not a small job, but worth it to get a 13 manual in- cheaper in the long run. Truck has a rebuilt motor in it, otherwise I'd have scrapped her and bought another new-used.
Good luck with yours. -
what SM codes? what MID 130 codes? what about 12 to 24 Voltage converter? it is weak thing

No faults in any module. I'm checking on cluster for faults. I don't have vcads. The trans goes into gears and neutral but the display don't work at times. Im thinking its a poor connection to communication from cluster to trans module. When those lines appears on cluster I'm not able to check codes in transmission but I checks in all other modules.

Really J1939 is used for cluster gear display. But dashboard use J1708 for diagnostics so I sugest bad wiring
