Transmission high temp

[Goober]

Freshly tuned 6.4 on a diet, SCT x4, light tow tune, egr still on. Has UD tunes, drove for a week or so light footed work n back. Went to head to work had engine light, pulled codes.. total of 4, p0607 I knew, cylinder 7 out of balance, trans temp excessive, one more but forget to record it. Cleared codes continued on my day..
Searching endlessly for ideas on where to start. I read a while back the tcm learning procedure but can’t find. If it’s needed ? Got a replacement tcm ordered, doing egr next day off. Could anyone help point me in the proper direction.

What is your trans actually reading temp wise?

Unfortunately I don’t know exactly. Trying to figure that out.. learning the new tuner

Tried to add Trans temp to gauges through x4.. not an option. Was checking through Vehicle info… under tcu swpn it’s showing a different tcm 7u7a- than what’s installed in truck. I have the 7c3a.. I’m confused now

You sure it’s not just a faulty trans temp sensor? Replaced many in the 5r platform
