Hi all driving 2008 model outlander, car runs like a dream, funny vibration noise when car in reverse at 1100 rpm, also when in drive at 1100 rpm, anything above and below that its quite. When in park same rpm no noise also in neutral. Check loose heat plates on exhaust system, tightened all plastics, could this be transmission or engine when there is torque at that specific rpm's tnx in advance
