Love the cat 7155 . I did find something out that isn't posted on the board that I could find. I have only seen this in 16th gear. but if you go down a small to medium grade and exceed 2475 rpm the trans will unlock the converter to keep from over reving the engine , you will notice if there is a hill right after the rpm will be up and your speed will drop. if you let off the throttle and back on it will lock back up. Thought I had a tras problem at first but found out it was a safety feature.
