Every system I’ve looked into requires you to enter “User Defined PID” for transmission fluid temp.
This is the equation for transmission fluid temp
in the pan:
((((A * 256)+ B)*(7/100)-400)/10)
And this is for the fluid temp at Torque Converter:
((((C* 256)+ D)*(7/100)-400)/10)
I use OBDLink MX+ and the above PIDs work and appear to be accurate.
