I have a 2006 2.5i Outback with an automatic transmission.. The previous owner is my daughter and I have verified that she never had the transmission serviced. I have been trying to figure out what to do, as the mileage is now 164,000. In going back through her records of service, I have found the following: 1) at 84,000mi., when the car was at Subaru dealer to have a dog guard installed, the receipt showed that the dealer found dirty transmission fluid that "appears to be original," 2) at 126,600 mi., when car was at a different Subaru dealer for something else, receipt had a recommendation for "BG transmission flush.) Then at 161,500 mi., I had the car at a third Subaru dealer for an airbag light problem, and they said the following: "found transmission fluid contaminated/burnt." I asked my daughter to take it to an auto repair shop for a safety inspection to see what they said, and the report came back saying nothing about the transmission fluid being a problem. By now I was frustrated and confused, since different garages said different things, so I took it to another shop for a safety inspection and they also did not mention the transmission fluid needing anything. At this point, I am starting to get obsessed with this issue. I am just learning about my car. My husband always took care of our cars and he was good at it, but he is not well so I am on my own now. But he says, fluids are important. Now the car is at 164,000 miles. I have been looking online and calling multiple auto repair shops and am now totally confused, as everybody says something different. The main difference of opinion is whether it is better to do a flush or a simple drain and fill. Other differences are, some say to drop the pan and look at it as a diagnostic tool (while others say they just remove the plug to drain); some say to change the filter while others say they don't unless it is leaking or damaged, and my son-in-law says he would replace it if he did the job himself, because he assumes it would be clogged, just like you always replace the filter with an engine oil change. One shop said if you do it yourself, be sure to get a genuine Subaru filter, while another shop said, when I asked about it, that they don't think Subaru has their own filters. I did look online and found a genuine Subaru filter that you would get from a Subaru dealer. So now I don't really trust the shop that said there is none, even though I got a strong recommendation from another Outback owner for that shop because she says they are honest. Honest maybe but I wonder if they know what they are doing. As far as flush vs. drain and fill, some shops say if the fluid is really dirty they do a flush vs. drain and fill, other shops say the opposite, that if it is really dirty a flush would be a bad thing. Yikes, how do I know what to do. I am obsessing about it this time and am paralyzed to do anything. Then, apparently there are different kinds of flush machines and one is safer than the other. I would be tempted to take it to the Subaru dealer but they charge $350 which is way more than any of the other shops that do flushes. Also, when I was in there for a repair, the sales staff were very aggressively trying to sell the people waiting for their cars to be done another Subaru. It was annoying. I feel like it might be better to go to a garage where they are not trying to sell you something. I guess I am saying I don't trust the Subaru dealer. I thought it was weird that three different Subaru dealers have said the fluid needs replacing, at 84,000, 126,000 and 161,000, and then at around 164,000, two independent repair shops did not even mention it. I talked to the manager of one of those independent shops and asked him why, and he said "the kid" probably didn't even check the fluid, assuming that the 150,000 mi. service had been done and it was not due for the next service. I had asked for an inspection and was prepared to pay for it, assuming they would check all the fluids. Unfortunately someone was not paying attention to what my car was there for and changed the oil, which didn't need to be changed. But, as part of the oil change, they supposedly check things over, but I don't think "the kid" did a very good job of checking. So now I don't really trust that place as being competent. So, to make a long, long story short: Help!!!
