If youre not sure if you should get this or even need this part pay attention. 20 year professional mechanic here. As far as the product goes... fits right in. Looks good, feels good. Cannot atest to longevity. I will update if it fails. Donot get confused with whether its brown or black. Tr690 and tr580 use the same solenoids. AWD solenoid ohms to 2 - 4.5ohms. The lockup solenoid (by far most common to fail), down shift solenoid and up shift solenoid are all the same and should ohm out between 10 - 13.5ohms at 75°f. 75 is important! If youre within a few degrees its cool but not if its snowing outside or solenoid is hot. My lock up was at 16ohms. No Bueno. No codes but a/t oil light was intermittent and car stalled on quick stops. Doesnt stall if shifted to nuetral before hitting break pedal. Pulled apart trans and inspected magnet and pickup screen. Looked into trans once valve body was off and inspected chain. Everything was beautiful. No metal shavings only a small amount of dust on oil pan magnet (typical wear). Checked ohms on solenoid once unplugged still 16ohms. Awesome now I know the wiring is good and not adding resistance. Looks like if you pull pan and valve body with front wheels on ramps you lose 11 quarts. Total quarts in system is 13 so ya get almost everything. Donot get generic CVT oil at the parts store! Only get what your cars actual spec is. Type 1, type 2, or type3. My 2012 outback with the tr690 takes cvtf-2. Subaru brand, idemitsu, and eneos where the only brands I could get my hands on in my area. Donot use regular atf or generic cvt. Change fluid every 30k to 60k miles. Was told this was a lifetime fill when purchased new but same trans in Japan they recommend every 60k minimum. Looks like subaru updates that here since I bought it as well. Inspected your oil and pickup screen. No its not a filter its a screen that keeps large pieces out. If you notice a lot of metal odds are you need a new torque converter. Lockup solenoid and actual torque converter problem have similar issues. Check your level and oil quality before you order anything. Be aware that once you replace the solenoid and fluid you may need to clear the TCM memory and do a relearn to completely fix issues. Youll need a scanner for this. Its super easy. YouTube it. If you don't have a scanner I recommend the thinkdiag bluetooth scanner. I use it at home while my high end is sitting in the shop. It made quick work of it and its like $120. It does about what my snapon did 10 years ago. Its a nice little scanner. Hope this helps

I installed this about 4000 miles ago and it is working great. Fixed a problem that a local mechanic quoted me as a $2000 job.

12 subaru outback with tr60 trans. Perfect fit. Solved the 0700 2764 error codes. Car now smooth and strong. Plenty of vids out there. Make sure to reconnect the manual shift pin when you reinstall valve body! Be well.

Im pretty mad. 1 of these went out about a month apart. These must be made with non copper wire, probably cca. I found another brand online and I will be cutting these open to see what exactly is the issue since im past the return window. They fit perfectly and function for about 10k miles. Then bam. They read short to ground. Please check the manufacturer and see if they switched to aluminum or tin wire.
