Some people have changed the solenoid pack which has the range sensor and pyrometer in it and some have found bad / oily contacts on the 23 pin trans connector or changed the PCM, but many never fix the issue. I am having that same problem with my 07 Grand Cherokee Limited. I have traced it down to DTC code P0884.

For the 2005 Jeep Grand Cherokee pcm problems, the car will show different signs that one should take seriously. The most notable one is the squeaking noise heard whenever one is making turns.

This will enlighten you on the slight possibility of this happening. If you compare the number of early (05-06 and a few 07's) 5.7's built vs. the number that have dropped valve seats, the percentage is not really DmkhE.
