After 10 trips to the dealer to fix shaking and stumbling when accelerating while cold, the dealer finally decided to replace the torque converter. After I got it back 2 weeks ago, the problems are now MUCH WORSE. When accelerating at any engine temp, the car makes a whine that sounds like someone sticking a flexible metal blade in a high-speed fan between 15 and 30 mph, the car makes several loud thunks when the trans shifts that feel like I’ve hit a large pothole, and there is a prominent clatter that sounds like pre-ignition or pistons hitting the valves when starting cold and a various speeds when accelerating up to around 60 mph.
I took the car back to day and was able to demonstrate the problem to the mechanic. They are replacing the transmission now. Only 42k miles and the trans is blown? My opinion of Subaru is taking a serious nose-dive. It’s required a dozen trips to the mechanic to get this far.
Anyone else experience similar problems? Is this car a lemon?
