Hey I just switched my 3.0 to a 4.0 but had to wire my transmission harness to the 4.0 engine harness and now it is stuck in limp mode what did I do wrong? I changed the ECU  obviously but kept the 3.0 throttle body and coil pack.  I have power to my range sensor but not sure if signal is getting back to the ECU
