2008 Ford Taurus Transmission and drivetrain Problems

“The wrench symbol and the check engine light came on after being parked overnight. The shift in the transmission is rough and jerky in motion. It did this when I first purchased and we had the code cleared and had a recall on the emission or PCM fixed by Ford. Now the lights are back on and the shifting is as I said earlier rough and jerky.”

“Transmission clunks into each gear when driving slow. When brake pedal is pressed to move shifter from park, there is an alarm that is fairly loud coming from the dash. The brakes seem to work well and I have maintained my own vehicles, so there is no reason this should be wrong with the car. It has very low miles for the year and has mostly highway driving. It has been this way for months, getting progressively worse.”

“This has happened about 3 times in the last 2 yrs but while sitting at a light my car suddenly went forward. It didn't go.to far. Maybe a ft or 2 but was enough to scare me. My foot was on the brake. It will also get stuck in gears and lose power on the road. No check engine light is on as of now. One light did come on today while sitting at a light and without notice my car would not go. It was the power throttle/transmission light. I turned the car off and then back on and it drove fine all the way home. It did jerk once. …”

“Transmission speed sensor issue: car would get stuck in high gear losing power at slow speeds. Attempts to put the car in reverse or park would cause a large clunk. Speedometer would also fluctuate uncontrollably during this time. Diagnostic codes showed failed output sensor and I had it replaced. Function of transmission after sensor replacement is still rough. The safety issue caused by this caused me to lose forward power several times while in traffic almost causing several accidents.”

“Car would suddenly jolt forward even though I was securely stopped at a light or stop sign. Sometimes, it felt like it jolted forward as much as 4 feet - even though my foot was firmly on the brake at all times. (I tried turning off the A/C to see if there was a power surge causing the problem. A/c on or off made no difference at all.) this would happen so often, that I would have to stop more than a car length away from all intersections or other vehicles already stopped so I would not hit them when the car jolted. It became an expected event . …”
