just bought my daughter a 2011 subaru outback wagon w/ 90k miles. great car! clean and all is good excetp.... it unfortunately, has the delayed shift into reverse and drive; moreso in drive. the first day of owning the car i had the transmission serviced and it did NOT help. just spoke with my personal mechanic, who i trust, who will be working on the car anyway to stop the exhaust rattling sound that makes the car sound like a piece of sh*t. i told him about this forum and the trans x mix formula and he is going to drain and replace what was just put in there 3 weeks ago. i sure hope i am one of those that can do the oh yeahhhhhhhhhhhhh it's fixedddddddddddddddddd shout! lol
will update once that service is completed next week and every now and then going forward
I wrote the original post here, and have kept track of its following over the years. The automatic trannys on 99 & 00 were equipped with some sort of a seal that gets lazy over time, causing delayed engagement of forward gears. (Subaru fixed this problem on later model cars) Trans-X works great to fix this problem on the 99 & 00 models. However, I am unaware of anyone saying that it will fix a 2011 auto tranny. It may help, or may do nothing. Use the smaller bottle 15 oz size, not the larger size bottle.
Also, be aware that a tranny drain only drains out half the tranny fluid. The other half stays in the torque converter. So, often, a fill then drain of 3 times is done, with short drives between drain/fills, to thoroughly drain out old fluid.
Another thought.......your 2011 may have the ECVT trans axle, which is far different tranny, then the older style auto 4 speeds with torque converter. If so, it is unknown if Trans-X will fix an ECVT. Let us know if you have the ECVT, or the older style 4EAT auto tranny.
