I just bought a 97 Outback Wagon 2.5 with 104k on it. It has a wierd transmission problem that I didn't notice when I test drove it.. When you stop the car and put it in Park, it feels like the engine is still under load. If you let off the brake, it doesn't go away till you shut the car off-then it settles back-like its in park. If you put it in neutral first, it doesn't happen. Any ideas? Thanks in advance, Eric.
