What owners report

The transmission will not upshift from low gear, from take off for awhile and give me the wrench sign, also will cut off the cruse control if being used or will not allow me to use it. After taking the vehicle to a transmission shop it was diagnosed to a faulty speed sensor, and was told that Ford put out a safety recall on this problem because the speed sensor has down shifted to low at highway speeds locking the rear drive up and causing accidents. I have check my vehicle recalls and did not find this recall on this. I have investigated this on the internet and found that there was indeed a recall on this problem. Why would my vehicle not be recalled to replace this defective speed sensor? Before a major accident happens.

Coasting to stop at intersection transmission did not disengage and engine suddenly accelerated to 2000 RPM. Held brakes and rear tires spun. I knocked trans into neutral and engine returned to normal. It has done this twice in 2 days. No floor mats and no contact with accelerator pedal. I did have a witness to this incident. Uncommanded acceleration -very bad! Is there a recall for this already?

2008 Explorer Sport Trac · Automatic transmission · 24,000 miles · Mar 2011 · crash

2008 Sport Trac v8 4 wheel drive. I must wait approximately 30 seconds before backing truck out of my garage...any sooner and the engine just revs but will slowly move after reaching 6,000 RPM. Truck also advances slowly from a stop. 1st dealer advised me it actually was 21 seconds and that I should just wait the 21 seconds before shifting to reverse. 2nd dealer cannot duplicate problem because it is intermittent and seems worse when weather is warm and humid. 1st dealer indicated they did a reflash of transmission but 2nd dealer confirmed they did not and accomplished it and shifting improved. Truck still does not downshift correctly to first gear upon coming to a stop or near stop and truck will remain in higher gear unless full stop and one second both occur. …

2007 sporttrac, started downshifting very rough when coming to a stop, took to freeport, il dealer who adjusted parts of the transmission, this made the downshifting much better for a few months, it is back now and worse than ever. You have to have your foot hard on the brake and don't stop very close to any vehicle or property in front of you. I learned hard way last week and hit a cement post with the front bumper, I had actually stopped maybe 6 inches from the post but the surge after stopped propelled me maybe 7-8", it is a very very dangerous situation. …
