2005 Mazda3 Tranny problems
 

I drive an automatic 2005 mazda 3. Several months ago, my AT light came on and my car refused to shift out of 1st or 2nd gears. The rpms would go out the roof whenever I tried to accelerate and my car wouldn't go above 20-25 mph. I had my transmission flushed, and the car seemed to be fixed. However, it all happened again this last week. I don't think the original problem was ever fixed, and I've read this is a problem with Mazda 3's on multiple Mazda forums.

What do you recommend I do?
