04 go with 136000 on it, purely stock. Just bought the car from a local dealership about a month and a half ago. On my way back from work today and this wining in the transmission started up. The more I put my foot into the gas the louder the whine. I would get upto between 40-50 and the whining would stop but it would seem like it was stuck in overdrive, or wanted to be in overdrive. After a couple miles of the whining and somewhat normal shifts I left an intersection but there was no whining, but it started shifting hard, and has been doing it ever since. When I get to the point where it shifts from first to second it almost slips but jolts the car forward. Checked the fluid, seems to look good and be at about the right height on the dipstick. Any help?
