  • 8.4 radio swap from 5” in my 2016 Cab N Chassis NO SOUND.

    RamForum · Datdamn3500 · 20 Oct 2026

    2016 Cab & Chassis. going from 5” radio to the 8.4 and the climate controls sorta work. (Speeds 1-4) and heat and ac work. My issue is I HAVE 0 Sound and I have the 7 speed fan, the media control by glove box. Obviously I can’t plug in the climate controls that came with the radio so I have to use my old ones and it hangs there. I’d like to find a plug and play harness that will allow the new controls/volume/tuning knobs as well as directly plug into the 3wire fan. (Mine is currently 2... Read more

We would appreciate any help to... Read more

  • U1437 Code on 2011 ram 3500 6.7 cummins

    RamForum · TTKC · 3 Oct 2026

    2011 dodge ram 3500 cab/chassis model So recently took truck in. I bought a brand new TCM and had it installed and programmed back on the truck. This was because of a bunch of codes popping on the truck. It fixed them all except one and we're at a loss here now. Code still popping is U1437. This code is TCM related. It pops up as "U1437 IMPLAUSIBLE INTAKE AIR TEMPERATURE MESSAGE RECEIVED". Cool so I replaced the air temp sensor. Didn't remove the code. Did a little more research on that... Read more
