!:::::! Automatic Transmission drain plug has a crush gasket (one time use) as opposed to a rubber re-useable one, so get a new crush gasket when you are buying your new AT Filter !:::::!


Howdy folks, thanks to USMB! Got me a 99 with 181,000. Same problem, did what rooster said, worked great. A little info for the guys doing it now: Trans-X was at my local Autozone ($10.99/quart). Small town guys might have to order Amsoil off of the net, depending, I live in a fairly small town, only one mechanic shop had Amsoil products for sale at $12.95/quart (cheaper than a new tranny). O Reileys, Napa, and Autozone all do not carry it here (did not check Carquest, forgot they existed to be honest). There are a couple types of the Amsoil ATF, I went with the "Signature". So you can't drain all of the ATF out (which is stated in this forum many times, just saving some searching) I pulled the plug and got 3.5 quarts out (I measured), then when I took the filter off an additional 1.5 quarts came out and was still coming out a little when I put the new filter on. So I ended up with 5 quarts total being drained out. After putting new filter on and putting plug back in with new crush gasket, I put 4 quarts of Amsoil ATF Signature and one quart Trans-X in. (Trans X says 1:10 ratio, capacity according to manual is 9.8 Quarts, so putting the whole quart of Trans-X in is fine. I ended up putting another half a quart of Amsoil in (I was just a little low before starting the process). Don't overfill, check when hot.  :D No more delay! Boom!



Regarding "FIXED,"
Trans-X continues to work well for me after many years now. No need to
seek out Amsoil ATF. Sure their ATF is very good, but using Wal-Mart
with Trans-X works just fine. I use the smaller pint size bottle of
Trans-X, don't recommend adding all the contents of a quart size
container. I have found that Trans-X works for about a year, then the
tranny delay slowly reappears. Just reapply Trans-X, and the problem is
fixed for another year.

Thanks for the tip on using the crush gasket. Good to know.

So, just keeping this topic alive. I found this thread while searching for additional information on my 2000 Forester transmission issues. This pretty much detailed my issues to a "T". I have a 2000 Forester with 72K miles on it. I bought it 1.5 years ago and it only had 48K on it (little old lady owned it). In the past 6 months, it has become more symptomatic. Monday evening, she went to the dealer service center. Today, they called me to say that she needed a new transmission, to the tune of 4100.


Impressive as it sounds, I pointed the Service Manager to this thread. He read it and agreed that is was worth a shot. A couple of hundred dollars as opposed to 4100. I will get her back tonight and hopefully this will help her out.


Glad I found this thread, and even more so that the Service Manager didn't rule it out...... Hope to come back with good news like the rest of you folks.

I originated this thread 6 years ago. If you try the Trans-X, it is important to fill and drain the transmission fluid three time, with short drives between drain and fills to mix the new and old tranny fluid. This is necessary because only about half of the tranny fluid can be drained at one time. The other half remains in the torque converter, and can't be drained.  All the draining and refilling does a pretty good job of cleaning out the old transmission fluid. Add the Trans-X upon the last transmission fill.


There is a drain plug on the bottom of the automatic transmission, so this is an easy do it yourself job. Cost of three large gallon jugs of tranny fluid at Wal Mart is about $50, so you can save yourself some money, as opposed to spending a couple of hundred bucks.


Yes, $4100 will get you a new tranny, if it comes to that. However, Subaru transmissions are well built, and generally don't break, so the repeated advise I have read on this forum, is to buy a used tranny from a wrecking yard for a few hundred bucks. It will come with a guarantee, and most likely come from a car that was involved in a wreck. Since the car was driven at the time of the accident, it is highly likely that the transmission was operating properly. Have a shop install the unit, and that will cost far less then $4100. IMO, it is not prudent to invest $4100 in a 15 year old car.

I don't question the investment itself personally. Once you do a repair like that you know it's good and that's something you can't get by replacing the vehicle with another used one.

I do question that totalk price though. I believe that transmission could be rebuilt for a lot less with aa good warranty.

That being said LKQ is national and if there is one close you can get a goof used transmission with an extended warranty including labor

No need to even look for replacement parts. Trans X fixes this issue. 72k is extremely unlikely that anything has gone "wrong" with the trans. It's the typical weakening of the seal that trans X seals up.


One of the rare times that a fix in a bottle is the actual solution.

Hello! just thought id chime in here with my 'before' experiences. i bought a 2004 subaru outback sedan in the summer of '14 but after driving it about 6 months it developed some type of electrical? issue that i just cannot figure out. it stumped me all winter, left me without a vehicle for almost a month until i was able to get my truck back to driveable. i had paid $3500 for this car at the time so i was very frustrated that it was just about useless not long after i got it. before this happened the car was driving fine but there was quite a loud knock from the engine when it shifted into passing gear going up hills, so i tried to take it easy on her.


fast forward to june 2015, i found another subaru outback sedan, a 2000, on craigs list for $450! car ran and was a daily driver up until january, but had to be parked because it wouldnt take a sticker and the owner couldnt afford parts ((it needed a windshield and tires)) i had to have it! i planned on keeping both of my outbacks so i could have plenty of spare parts. this second one ((ill call it 'the purple one', the 2004 is 'the white one')) was purchased and i had AAA haul it to the garage i work at and the next day we put it up on the lift to look her over. thats when i discovered the ROT! sooo much rot that the rear K frame was very close to being snappd right in half, and it was giving the rear wheels this terrible gangster camber affect lol! she had apparently been driving it like this for awhile because the rear tires were worn down to steel, and one of them was the spare which was also showing wire. while this was discouraging, i did have a complete parts car at home in my driveway, so i had it hauled to my house where i proceeded to swap the rear k frame all as one section with the rear diff, brakes, and struts still attached. now that that part was over, i did a timing job on it, ((car was at 212,000 when i bought it, and there was white crayon on the timing cover that said 116k)) i took swapped wheels off my white one since those tires still had more than half life left on them, changed the spark plugs and wires, changed the oil, all the filters, got it all legal to drive on the road.


it drove fine for a week or so, though i was noticing a delay when putting it into drive, which like others have stated would go away with a little big of revving. i hated doing that for fear of breaking something, so i would put it in drive and just sit there for 5-8 seconds until i felt it go it. after that it seems to shift fine going down the road. it did leave me stranded at a stop light one time where it just wouldnt go anywhere until i shifted it back through the gears..very embarassing! that night after work i bought a new pan filter, spin on filter, and fluid, and changed it in the driveway. i hadnt even researched anything yet but i figured this car had obviously been neglected for however long the previous owner had it, and could prolly use the fresh fluid. it seemed to shift into drive nice and quick that night when the new fluid had just been added and i was running it through the gears to check the fluid level. but then the next morning it was back to having the delay again. very discouraging.


i was actually doing some reading on a transmission swap when i found this forum. i was very close to just swapping the valve body from my white one into the purple one if in fact they were the same, to see if that would cure it. but now im going to pick up some of that trans x and try that instead. i seem to be having the same issue all of you have had and im hoping this solves it for me too! its nice to know that i do already have another transmission at my house i can use if it doesnt, and where this car was so cheap i dont mind putting all these labor hours into it especially since it helps me justify having wasted so much money on the white car that crapped out on me so soon. at least im getting my moneys worth out of it in parts lol! so hopefully tomorrow after work i will have everything i need to do this. where the filters were just changed about a week ago, and 5 fresh quarts were added, i think ill be ready to drain the pan again and add more fresh fluid along with the treatment and that should leave me with mostly all new fluid. 


sorry for the long longggg post but..im a woman and i like to thoroughly explain myself :P
