LML Commanded Pressure Issue

[07nastymax]

I tried searching with no luck for my specific scenario. I have a 2012 LML that is commanding desired line pressure of 27psi at idle and spikes as high as 127psi while driving! I have tried with and without trans tuning and no change! Do I have a TCM issue? Thanks for the help in advance!!!

There is no commanded pressure. What are you using to moniter pressure?

I noticed this after I installed my EZ Lynk and selected the Line Pressure PID. Every truck I have ever installed and setup the gauges with the line pressure pid shows 80+ psi at idle and spikes as high as 288psi through the EZLynk app.
