Only have 78k miles on this truck. About once every 3 to 4 times I put the truck in reverse or drive, nothing happens and I just sit there. After an average of 3 to 15 seconds, the transmission makes a hard THUD noise and it finally begins to move into gear. The other day I randomly had a -??wrench-?? warning appear as I was going down the highway at 70mph. Once I got home, I shut the truck off, restarted it and the wrench disappeared.

My Wife and I picked up my granddaughter at her school and I was driving her to our home. My speed was at 40mph in -??drive-?? and all of a sudden it had very hard downshift into what appeared to be first or second gear. -??Wrench-?? icon alighted on driver-??s display monitor. Put shifter into manual and drove about 2 miles then shifted back to drive. Drove truck home and called Dealer. Truck went into shop and was determined output sensor failed. The Lead Frame had to be replaced at cost of $1600. Personal safety was at risk due to amount of traffic on road. However I immediately realized I had a problem and acted accordingly.

Without warning, the transmission on my 2014 F150XLT 5.0 will shift from either 5th or 6th gear down to 2nd gear. This causes the tachometer to nearly red line and a sudden deceleration without warning for drivers behind me by activation of the brake lights. Several crashes have been narrowly avoided at highway speed because of this fault. There are no warning lights or buzzers activated on the dashboard when this sudden downshift occurs.

I was driving down the road at 75 mph when all of a sudden my speedometer started going from 75 down to 30 back up to 65 down to 35, etc. Then my truck downshifted and slammed me into my steering wheel. It felt like I had hit my brakes hard. I have video of it This is a recall on the 2011-2013 but my truck is a 2014 so I feel they should cover my issue as well.

Truck loses power suddenly and even while going down the road randomly tried to shift itself into reverse. Lately it has just been lose of power.

- Junction City, KS, USA

The vehicle at highway speed of over 50 MPH will suddenly downshift into 1st or 2nd gear causing the tachometer to spike past 4500 RPM and the vehicle to suddenly lurched to an almost stop and shake. When this first occurred I thought I had done something since it corrected itself once I took my foot off the accelerator. This has occurred on numerous occasions since that first incident and one time I had to put the vehicle into neutral to alleviate the lurching while the engine still revved up past 4000 RPM. Very nerve rattling. I am afraid this will cause an accident if I'm traveling on the highway and the vehicle suddenly slows down while I;m being followed by another vehicle. I took the vehicle to a recognized reputable transmission place who could fine nothing wrong but stated the condition sounded like a some sensor is sending erroneous information. Very frustrating to have this happen on numerous occasions and yet no issue found. I should not have to be downshifting into neutral when ever this occurs, this is also dangerous.

Transmission at HI way speeds will down shift, RPM's will come up and wrench light will come on till you let off accelerator pedal. Vehicle surges forward at this point until it upshifts back to correct gear.
