I have a 2005 Jeep Grand Cherokee with the 5.7 Hemi and 545RDE. I can read and tune the ECM but it will not let me read the TCM. What one do I choose?

Unfortunately your controller is not supported for the trans side. You can swap in an NGC4 controller and it will open up the trans side.Originally Posted by [email protected]
