The issue I am having with my 1999 Outback (2.5 liter engine with 120,000+ miles) is this: vibrations felt and heard while the car is in gear (an automatic transmission) and at a stop. Also a vibration is felt and heard while the car is Park or Neutral and the rpm’s are up to around 1,200 or so. Up until last year this car has run well and never let me down. Last year (3) timing belt pulleys and (1) timing belt adjuster had to be replaced and shortly thereafter my right-side CV shaft was replaced. Since then I have had the car into (3) different repair shops for a diagnosis and evaluation with no positive solution. Shop (#1) replaced the CV half shaft twice first because of a torn boot and the second time because it could be defective and be causing the vibration issue…apparently not. Shop (#2) replaced the transmissions torque converter because of the vibration issue…didn’t help. The transmission and drive train were looked at and everything out fine. Shop (#3), an independent Suburu shop checked the motor and transmission mounts (they were fine) and replaced the harmonic balancer (didn’t help) and told me the vibration issues were engine related (internally) but that’s all they mentioned. Has anyone experienced these vibration issues on an automatic Subie before in gear and at a stop and from Park or Neutral idling up to 1,200 rpm’s or so? I would like to find the root cause for this troubling problem. Thank you all for any suggestions.
