Transmission started slipping upon heavy acceleration, took into Ford dealer who were not easy to deal with.... Next day they said they were replacing valve body - common failure among 6F35 transmission.
Car came back with a transmission whine upon running at full operating temperature. Transmission fluid level was also found too high, but that did not relate to the whine, car still has to go back.
Transmission is still acting up, hasn't been right since 1-2010, dealer cannot fix it.
Car is a lemon - faulty transmission since January 2010
Transmission was slipping severely and "whining". Car went in for transmission overhaul and after a week problems are just as bad again.
Transmission whining, very obvious and everyone BUT Ford dealer acknowledges it.
Transmission failing to shift on highway. Severe slipping and banging. Failure to reset to 1st gear at stops when coming off highway
Transmission replaced but didn't solve problem: slipping while going uphill, hard shifting. New transmission removed twice, replaced valve body, solenoid, and PCM, still didn't solve problem. Hav refused offer to replace trans again, want buyback.
I finally agreed to allow Ford to install yet another transmission. This one at least appears to have resolved the issue.
The transmission slammed into reverse. I have had and apparently continue to have problems with my transmission.
Intermittent transmission problem. Jumps out of gear at high speeds (around 70 mph). Dealer not able to replicate. Third time in for repair.
Recently noticed a leak under the car and my RPMs jumping as I accelerate. Turns out my axle seal needs to be replaced and transmission fluid is leaking. According to the service mgr (and what I read on the internet), Ford is aware of it.
Took it in for harsh 2-3 shift and intermittent RPM flare between same shift. Was told could not duplicate.
Took back to dealer a few days later after voicing displeasure with last repair trip. They kept the car for 4 days and still told me they couldn't duplicate the problem. Less than pleased with Ford and this troublesome 6F35 transmission.
Transmission problems - clunking noise/feel when changing gears. Shop could not replicate nor did codes show anything wrong so nothing was done.
Transmission would clunk when slowing down and started shuddering when accelerating or decelerating. Dealer could find nothing wrong. It had this problem since 25,000 but became more and more frequent.
