Well I think at 220,000, my 4EAT transmission on the 2010X has a faulty torque converter clutch solenoid and.or something blown in the converter. I keep getting intermittent P0741 code while going up grades on the interstate. I've been religious about changing fluid every 30,000mi, but I guess that can only do so much. Have any of you gone through the transmission replacement and can comment on how well it went? I'm getting quotes from reputable shops for around $3700 which I feel like at that point I get rid of the car and move on.

I swapped a pre 2000 Impreza transmission onto my Son's (and before him: Daughter's) college car.
Got the transmission off of Craigslist for 250 bucks, I seem to remember.
It wasn't a horribly difficult swap but do suggest you get a transmission lift (Harbor Fright is your friend here).
The hardest part was putting the wheels on enough cribbing to raise it such that the old was able to come out and the new in. At that time, I did not have a lift so needed to improvise.
It was quite a sight to behold since that little car sat as high as a mini monster truck at the time. People stopped their cars to ask me what I was up to.

After my son got his CrossTrek, I gave the Impreza to a friend of mine that was low on money and needed a car.
It had over 250K at that time. That was 2015. It is still running well.

So can it be done? I think so..

Thanks for the thoughts Remco. Since I use this forester for work, regularly driving 300 mi from home, I do need it to be decently reliable....which my wife suggests is not possible anymore at 220,000 mi. I havent had a shop do anything major as a trans or engine swap before so it just makes me nervous about this turning into a money pit project.

Why are you thinking you need to replace the entire transmission? It's not a CVT, it's repairable. From what I can see Subaru does not sell the individual solenoids and you have to buy a new valve body. I saw a thread from 2016 where someone was quoted 1250 by Subaru to replace it on a 2010. I would try and find a specialist Subaru shop, a dealer, or the transmission shop with the best rep in your area. It's really not clear to me why you are shopping for a transmission replacement. A failed solenoid is basically a valve that is no longer opening the way it should. To me, it would be like throwing out a garden hose because the gasket at the tap connection failed.
While I understand your wife's fear, it doesn't sound she has a lot of knowledge about mechanics. My wife is much the same. But of course, a new car is not always the answer to dependability concerns. My father in law's 2019 Forester suffered a mystery power drain and required a boost to get started after sitting 2 days. Dealer thinks it might be linked to the Radio having remained on, but basically they do not know. I suspect it will have to happen another time or two for them to diagnose the issue. It is great to have roadside assistance but it is still a pain to have to use it.

I'm not shopping transmission replacement. I'm looking at solving my P0741 code.....which, in talking with several shops indicate there's a good chance I'll need to replace the transmission because the car has 220,000mi. The shops say that at that mileage, P0741 could be a host of issues (including blown seals on the torque converter) and not limited to a bad solenoid and that even if it is a solenoid repair, at that mileage I may be wasting my money on a repair......my gut tends to agree with them and I dont have weeks to have the vehicle out of service.

Well based on the above I think the solonoid can be tested, and that maybe some money spent on a diagnostic would be worth it. When was the last time the transmission fluid was changed? That might be something cheap to try, and the condition of the fluid, and metal or not on the plug might be revealing.

Personally I think (unless you know the mechanic well) that might be a spiel to suss out how much you are willing to spend while doing the absolute minimum in terms of an actual diagnosis. How is the rest of the car?

I've been pretty good about ATF changes.

Engine burns about a quart per 1500mi, front diff leaks, and I cant yet figure out exactly why I have poor mpg (might be due to failure of the TC clutch selenoid). Other than that the car is in decent shape.....suspension was overhauled. Rust isn't too bad.
