Explorer Sport Trac XLT 4.0L V6

  • Automatic transmission
  • 115,000 miles


I learned that my truck don't have a dipstick and I added the correct fluid to it after the trans line leaked on a road trip. Now at 150,000 miles it overheats and a burning smell of trans fluid and low power at take off, also a whining noise from 1st to 2nd gears. No other problem I had for as the tranny. I think the fluid they require you to refill is not the correct fluid because this started after I researched what type it uses. Guys what i think is that the trans need fluid and filter replacement after 100,000 miles and another type of fluid is required. From my diagnostics the torque converter has become weak due to the type of fluid they recommend to add. Servo pins is failing because the type is a non serviceable trans, yeah but the non replacement of trans fluid and filter can do a lot of damage. It's a failed product from ford. I repairs trans and if you like your ford change your fluid and forget what the manufacture requires. So this summer 2017 I will research what type of fluid is required for my 2007 sport trac and I will share it with you guys.

Explorer Sport Trac XLT 4.6L

It would be nice if the dealership did not lie to you about the transmission. They told me that it is sealed and never needs transmission fluid. Never needs servicing. I call my local mechanic and he says that the dealer would have to add fluid if it needed it. Why would you manufacture something that only a dealership can fix? Sounds to me like it was manufactured for Ford to get all of the business. Mark up the price, if you are the only one who can perform the maintenance.

I was a Ford man at one time but I will never buy a Ford product again. Toyota or Honda from now on. GM and Dodge took bail out money ( welfare and food stamps). Whatever happened to good ole customer service? Sounds like all of us that own this piece of crap needs to file a class action lawsuit.

Explorer Sport Trac LX 4.8L

  • Automatic transmission
  • 66,000 miles

The Sport Track 4.6 L 4 x 4 transmission has no dip stick to check the fluid level. It is necessary that you take the auto into an agency for fluid check. Please remember this is a sealed transmission that is supposed to never need service.

The operator's manual says, "If you notice any unusual performance take the auto into any Ford Dealership and have the fluid checked.

I noticed during a trip home from travel that the transmission was acting unusual after high speed travel. I found a dealership in Safford AZ and stopped to have the fluid checked. They indicated no available time and simply said they were sorry. I asked for a form filled out indicating they would not check my fluid level because I live in the wilderness and the next agency was 200 miles I wanted Ford to know I was told to drive on! They said they would check the fluid but not fix any problems...they result was fluid that was showing signs of air bubbles. The agency said to simple have the fluid flushed so I next traveled to a nearby Lube & Tune. I was told the sealed transmission can only be serviced by Ford and they need the service work.

The next stop was Ford, again no time to service so I was told to travel on.... Each time I shop I travel 160 miles to the store...I live in the largest wilderness area in the lower 48 states...it was the first National Wilderness declared and named the Gila. By the time Ford is able to check and or service the transmission it will have more than 500-600 miles additional.

The service person at Ford simply indicated to "never by an all wheel or 4 wheel drive Ford. New 4 x 4 Explorer's are not really 4 x 4 but connected using a transfer case with no neutral so it's always spinning. This would be like a rear end with no ability to turn a corner without grinding tires. That's what the rear end does, lets two wheels rotate at different speeds but Ford has a better idea, simply destroy hardware.

Summary, the Ford 4 x 4 is a cheap excuse for a car with on ability to really be out of 4 wheel drive...this is not an all wheel drive but what you new get.

Be aware you will always require four tires, never two! you can't check fluid in the transmission without taking to Ford dealership but they have no time to check.

My suggestion is to buy 2 wheel drive and have the car towed out of any location you get stuck in, it's cheaper.

Waiting for a Class Action Lawsuit against lack of service causing damage....

Explorer Sport Trac Limited 4.0L V6

  • Automatic transmission
  • 90,000 miles


I've had my 2007 Sport Trac since July 2006 and put over 20,000 miles per year on her. Starting just before the 100,000 mark, the transmission began hesitating between 2 and 3 gear. The engine will wind up but the transmission will not shift into 3rd. Then I take foot off gas and rev up again and then it will shift. Sometimes a screetching noise will come from the undercarriage during this shifting. This is an intermittent issue and only seems to occur during warm days or in the afternoon commute.

I took it to a transmission specialist and they confirmed what I have been seeing on forums regarding the 5R55S transmission. The servo pin bore wears out over about 70,000 miles and the fluid begins to leak through the valve. From what I can tell, the issue will get worse to the point where it will not shift from 2 - 3 and the overdrive 5 gear will not shift either. This is an epidemic problem with the 5R55 series transmissions. There is a bulletin fix called the "Servo pin bore repair" where a transmission specialist will bore out the servo pin and insert a sleeve. This repair can cost around $800 - $1000. I called a local Ford dealer's service manager...he said he can do the bore repair but that in his opinion it's a difficult repair to make and that the benefits are minimal...may extend the transmission another 15,000 miles. His advice was to replace the transmission for around $2600 - $2800.

I'm looking to trade in :(

Explorer Sport Trac Sport Track V8

  • Automatic transmission
  • 20,000 miles

My vehicle has been to the dealership 3 times for this problem. Everytime I am told that Ford has not figured out how to fix this. This problem is not only with the explorers that have the new six speed transmission but the f150's as well. The transmission specialist at the dealership finally told me to drive it really hard and when the son of a bitch falls out on the ground they will replace it.

I do not feel comfortable driving my kids around in this vehicle and intend to get rid of it soon.

I live in Alaska where the road conditions nine months out of the year require a lot of effort to maneuver. This vehicle has been a pain in the ass all winter to keep on the road and keep from sliding thru intersections while the car decides which gear it wants to be in.

I am told it is a delay in downshifting from 3rd to 2nd ( which it often skips and goes right into 1st) that causes the lunge forward when stopping. But now it has a delay when you take off. Almost like an auto clutch trying to engage at 2500 rpms.

(reported on)

Explorer Sport Trac V8

  • Automatic transmission
  • 8,000 miles

Transmission hesitates/slips, then slams/bumps into gear after slowing down for a yield sign, not quite stopping, and then accelerating normally. Only seems to occur after slowing down from 2nd or 3rd gear into first. Doesn't occur if remaining in 1st gear and slowing driving forward (as in a parking lot) and then accelerating. Dealer contacted Ford. No bulletins available. Tested another Sport Trac, same year, more miles with same result. Told to live with it unless/until it breaks.
