Transmission failure at 77,000 miles, June 2010. Replaced with Ford part at Ford dealer. Replacement transmission lasted 3 yrs/8 mos, and lasted 45,000 miles (8 months beyond warranty). Ford will not acknowledge the problem, or provide any relief whatsoever in resolving the problem. Transmission failure at any point, at any time, could be very very dangerous.

O/D light suddenly starts flashing while driving at normal surface street speeds of 40 - 45 mph. Within 10 miles, the transmission started slipping and it felt like the vehicle was laboring; my wife thought the emergency brake was engaged. She never made it home - within minutes, the vehicle slowed, would not accelerate and subsequently broke down. The vehicle was towed to the nearest Ford dealer who determined the transmission was a total loss. We purchased the extended warranty when we obtained this vehicle from said dealer. Although we had well over 10,000 miles left on the warranty, it had expired less than 4 months ago solely based on calendar days!! this is a secondary vehicle for us and does not get a lot of use; less than 10,000 miles a year. Both the dealer performing the repairs and Ford Motor Company customer care were surprisingly unsympathetic to the circumstances and were unable (or unwilling) to make any concessions. So, $4,200 and a week later, I had a 'new' re-manufactured transmission. I was somewhat suspicious of the sealed transmission - one that does not have provisions to monitor the transmission fluid - which was manufactured and installed on the 2003 models. After looking into this issue, it has become quite apparent that there has been an inordinate number of these transmission failures on similar vehicles. I expect to get at least 150,000 miles from my automobiles - and I have with a few other vehicles from another us manufacturer. Consumers who use their hard earned money to purchase us manufacturer's products should expect a reasonable amount of quality, reliability and customer service. It is very unlikely that I would consider Ford for my next automobile purchase. Mileage at failure: 111,846.

I was driving down I-10 at 3:30 in the afternoon on my way home and my 2003 Ford Explorer out of no where went in reverse I was about an inch away from hitting the car behind me. My children were crying scared and I too was shaking tried to make it home but my car wouldn't go past 20mph and we got stuck at the gas station had to get towed to my house. I have been told that I need a new transmission and cannot afford one I just bought the car a year ago. Thank you Ford for almost killing me and my children!

While driving the O/D light began flashing on my dashboard, the vehicle slowed down to about 15 miles as if the transmission was pulling/slipping, the car made a hard jerk and began to pick-up speed. This cycle repeated until I reached my destination. The light came on again the next day and the same events occurred.

Transmission is not shifting into second gear and overdrive. Overdrive light flashes. Previous owner had a new transmission put in through Ford Motor Company and it started occurring again within a week of the replacement. I purchased the vehicle in April and have had it to numerous repair shops for transmission filter changes and tune ups, nothing helps. Now im told it needs a new transmission. The transmission in it now is only 8 months old. It revs really high after first gear then kicks into second only after letting off the gas and manually shifting with the shifter. It will not shift into overdrive at all. The overdrive off light is constantly flashing. I highly doubt my next vehicle will be a Ford!!

The vehicle was driving down the highway when suddenly the O.D off light started flashing. When it approached local streets I noticed the transmission was slipping going into 2ng gear. The vehicle was taken to the dealer who immediately diagnosed it as a defective transmission. A little research on the 03 Explorer transmission indicated it was a 5R55S model which has an astronomical failure rate. Its also a sealed unit which doesn't have a dipstick to check the fluid level or condition ( burnt smell). The Ford Explorer also leads the list by having 4 out of the top ten vehicle complaints for worst model years cars. All the top complaints are for transmission failure.

While driving my vehicle on Sunday, while driving my vehicle stalled in the road. The truck felt as if it was trying to pull a hill. This was very scarey for me and my children because if someone was coming behind us or if I was turning into the flow of traffic this could have been a terrible accident. Afterwards the vehicle couldn't go over 30 mph without shifting out. This is very dangerous and Ford should recall this immediately before someone is killed.

Transmission failure.

- Oak Creek, WI, USA

I was driving my 2003 Ford Explorer and I was going about 40 miles per hr. I was approaching a red light, and as I was braking my vehicle accelerated without me having my foot on the gas paddle. I have had major transmission work (re-built trans, $3000) on my vehicle, in which I had to take it back to the transmission repair shop three times, yet I continue to have unexplained problems. The vehicle seems to be unsafe for me to drive at this time.

- Columbia , SC, USA

Without any prior indication of an issue, the overdrive light started flashing. After stopping at the next traffic light, it appeared the transmission was having a problem getting into 2nd gear. Needless to say, the tranny problem continued and now needs to be replaced. This issue seems be consistent with that of many, many early 2000S Explorer owners. I feel an investigation into this issue is warranted.
