Recently replaced the manual transaxle 2003 Legacy outback, after a very short road test the transmission began to shake really bad. After determining the rear differential is 3.90 and the transaxle is 4.11 I replaced the rear with a 4.11 now I have a different vibration after a longer road test. Question, could the viscous coupler in the transmission been damaged on the first road test? Anyone else had this issue? Any info on this would be appreciated.
