Just bought an 05 2.5i with 84,000 miles and a 5EAT about 3 months ago. A month ago it starts with the slipping described in this thread. I checked the fluid and it's super high, like twice the amount needed. I drained it off and the problem compounded, now when it's cold it won't go into D at all. It'll drop into R, but not D until it's warmed up. It takes about 10 min or so and then it'll drop in. Once on the road it shifts like a brick for the first 15 min or so, then it's fine.
I'm changing the fluid and filter today (who knows when the last time it was done)
any suggestions?
