The AT on my Outback seems to operate normal except for a noticeable vibration when the car is in Drive and say you come off an interstate highway exit to a complete stop. If I pop it into Neutral then back to Drive it feels normal. Is this a sign of a problem or just they way Subaru AT's are?, BTW I changed the AT fluid to see if it helped, It help some but the vibration is still noticeable, just not as bad as before the fluid change.

i would try another fluid change or 2 and add some kind of additive...i have read numerous posts here about people who have had problems with there automatic transmission and the problem has been solved with a little additive and fluid change.....though i think the "Additive" is designed to swell the seals....check out the related threads at the bottom of the page.....

I added a pint of additive to the fluid change. I will give it a couple thousand miles to see what happens then I might add 4-5 quarts of Synthetic fluid...
