I have a 2000 lincoln ls v6 with 124,250 miles on it. The car seems to have problems shifting into 2nd and 3rd gear and going into reverse. If I were to floor the pedal, the car will over-rev and take a while to shift into 2nd and 3rd gears. The only way to get it to shift correctly is to wait for the engine to hit the correct RPM, release the gas, and press the gas again and then it will shift into 2nd gear. On top of that, if I were to shift from Drive to Reverse, the whole car jerks right back with just my foot on the brake. Can anyone give me a possible explanation why this is happening?
