I have the opportunity to buy a xc90 pretty good deal It is the model that is known for transmission issues. T6 2004. My question is, the dealership replaced it with a new transmission at 88k miles. that makes me nervous already that it needed a new one. But if they replaced it does that mean I shouldn't worry about it anymore. Or is there still a chance something can go wrong. I don't know much about what happened with this whole issue. Would love input as this car is for my teenager and I want it to be as safe as possible...THANK YOU
