Bought a Subaru because they're known to be reliable and I live in Colorado where 4wd is nice to have. I guess mine was neglected by its previous owner. 2001 forester s, automatic 180,000 miles. I replaced the engine back in December w/ a used but much lower mileage engine, it runs like a champ. The original engine spun a rod bearing 24hrs after I bought it, the previous owner was a nice guy, felt awful, and gave me some money back to help with the repairs.
On to my current issue. Driving home yesterday I lost power suddenly, no bang or hard shift just engine RPM shot up and the speedo did too although I was coasting and slowing down. I pulled over, put it in park, and checked fluid level, its fine. put it back in drive and it drove normal for another 1/4 mile before it did it again. Luckily I was close to home so I limped I home. it began shifting hard in to gear and not staying in gear. it isn't slipping, once it does engage it accelerates and drives fine. it's the shifting that really is the problem. it operates in reverse normally. Also, i've lost park, I put it in park and it made a grinding noise, frightened I quickly put it in neutral, I backed up the car and pulled forward a bit, tried again, it made the same noise briefly but stopped, it still did not engage and rolls as if I were in neutral. I've done quite a bit of research and have found this handful of symptoms(except the park thing) can be caused by the line pressure solenoid and/or the resistor on the RH strut mount.
Unfortunately I believe the shock shift broke my right front output shaft or something else inside the front transfer case as the output shaft is sticking about an inch out of the case. this might explain my park issue? I love my forester but damn, another 1000 or so in repairs and i've paid for this car twice.
I did a drain and fill and added trans-x to see if that would help the symptoms or maybe free up a clogged valve. I guess i'm not that lucky, and now with a broken xfer case it certainly wont be an easy repair.
both the engine and trans have gone out with no previous signs of trouble. the car was acting perfectly normal that morning on the way to work and since December when I put the engine in it.
