PENS87

I can say that after the first change (3.75 quarts), there was no improvement. After the second ATF change plus the Trans X, there was a noticeable improvement but I'll also say that the improvement wasn't appreciable until the next morning (despite taking the car out for a ride and cycling it through the gears many times). It is certainly possible that given the capacity of ATF (9.8 qts.), that 1 change wasn't sufficient but given the fact that after the second change there was a time period between the ATF change and noticeable improvement, I'm thinking a few hours were needed for seals to swell so the tranny could hold pressure. Not a scientifically controlled experiment by any means & as you indicated no data on the 2007 (though this may be the first). Based on my limited experience with this issue, I'm not convinced Subaru fixed this problem after 2000. Any others with model years after 2000 have this problem (AT with delayed engagement into 'D')? Definitely appreciate the reply - thanks for taking time to share your thoughts & opinion as to whether to keep or sell.

Hi All - New to this forum. Looking for input on this issue - Specifically whether to keep it or trade it. 2nd owner of a 2007 OBW Limited AT with 72K. Purchased a little over 3 years ago with 45K on the odometer. Had the external head gasket leak which I had the local dealership take care of (with some help from SOA! last Jan) otherwise has been good until this July. Started with the delayed engagement issue from either 'P' to 'D' or 'R' to 'D'. After reading extensively -- this forum was most informative - Fluid was not low but admittedly dirty. I did the drain x 2 -- replaced with Subaru ATF and Trans X ensuring proper levels. Problem has gone away but question for how long. I see Rooster2 gets about a year out of this 'fix' by swelling the seals so pressure can build & have read success from others but for how long? Don't see many long term reports other than Rooster2. Got a new Rex on the way but wouldn't mind making it more of a fair weather car if practical. Trying to determine if I should trade (or privately sell) the OBW while its still functioning well or keep it (worried that things will turn South). So, bottom line question - For those of you that have found this TransX 'treatment' to be effective, how long has it lasted you & does repeat drain and replace with fresh ATF & TransX get you going again if the tranny starts acting up again? Thanks!
