I have taken my Jeep to multiple mechanics and have been told multiple possible scenarios. However, no one has found the true issue. Story goes as this... I’m driving down the road and shift into 5th gear, at about 55+ a flutter noise begins. It continues even when the clutch is depressed. The only way to get it to go away is to down shift and slow down. I also have little to no drive power during that time. Has anyone else run into this issue? It has a new clutch, throw out bearing and pilot bearing. Thoughts?
