B-Rad50

I just picked up my 2021 Express and it has the 6.6 & 6l90 and it sure would be nice to even see what my trans are temps are getting up to. I don't live in a cold climate and I didn't have a second trans cooler on my previous Silverado 1500, so I installed https://globaltransmissionparts.com/...ystem-stl010/. I towed my 33ft travel trailer with my Silverado's 6l80 at around 170 degrees on warm days up hills with the above part installed. With my Express I tried going the OBD2 route with the Torque app like other threads suggested and the trans temp was not supported. It's not the end of the world but it sure would be nice to monitor the temps while towing.
