Ford F-150 (2009-2014) :: 2009 - 4th Gear Intermittent Slip At 88K Miles
Oct 27, 2013
Started a while back and comes and goes. Only commonality I have found is the truck needs to be warmed up for it to happen and usually after a few hours of driving. The downshift from 5th or 6th into fourth, at times, produces anywhere from a light to violent clunk, feels like a typical tranny slip. It will do it while in cruise and it will do it if I don't have the cruise on. Can't figure out if it is going to be a tune issue or hardware.
It does it only downshifting into 4th from 5th or 6th, no other downshifting is a problem and usually the 6th to 4th produces the worst results. At highway speeds that is usually a shift from around 2Krpm to just over 3K rpm (6th to 4th) if it is from 5th it is about 2500 to 3K. Start from a stop and go WOT and there are no issues.
Having it in Tow/Haul or not makes no difference as far as I can tell. IT can do it on one hill and the next time be just fine or do it 2-3 hills in a row. After this last trip it will do it at 9K feet or at 60 feet elevation, didn't make a difference there either.
Another issue that may be hurting the computer is the truck originally came with the 235 tires, it now has 285's and the rear is only 3.31. I plan on going with 265's and maybe still a gear change to 3.73's in the future. I usually only notice this on long trips, first was a 1500mile hauling an ATV, second was last week during a 2500 mile empty. Although I have had it do it a few times locally. I figure those bigger tires can't be good especially with that high of a rear for the management system.

2010 STX with 4 speed (4r75E)... Yesterday morning when I was almost at work(20 minute drive) I went to accelerate from a stop sign and my truck acted like it was in neutral. Once the rpm's dropped to just above idle speed the transmission caught and I was able to accelerate as normal. I guess I didn't think much of it until I was coming home from work, again about 20 minutes of driving, when I was accelerating while turning left from a stop sign. Halfway through the turn my rpm's shot up to about 5000 and it was acting as if I were in neutral again. Just as before, when the rpms dropped to just above idle, the transmission reengaged and everything was normal.
I decided to take my wife's van to Walmart and grabbed a bottle of lucas oil "transmission fix". I figured it might buy me a little time before I am able to get it to a shop for diagnosis. I used a suction pump to remove approx. 24 oz. of tranny fluid through the dipstick tube. I then added the lucas oil "tranny fix" (24 oz. bottle). I inspected the fluid that I removed. It looks pretty dirty. I would say that it was a nontransparent brown color with a slight red tint. when poured onto a paper towel it still looked brown. It didn't smell burnt at all. I checked the fluid level twice before I added the lucas oil, and twice after. Both times the fluid level was at the full mark (fluid at normal operating temp, with vehicle in park after shifting through all gears).
Fast forward to today and I was able to drive from my current house to my new house(being built) which was about 10 minutes away. I had no issues at all with the transmission. after being at the new house for about an hour and a half I came back home with no issues. about 30 minutes after returning home I headed back out again to run some errands. About 15 minutes into the drive my transmission slipped again as I was making a right turn into the barber's shop parking lot. after about an hour at the barber shop I headed for home again. As before everything was fine for about the first 15 minutes until I tried to make a right turn after sitting at a red light. the transmission slipped as described before, but it did it twice this time in the same turn. Nothing happened after that within the last 5 minutes of driving home.
The slipping only seems to happen when accelerating from a dead stop or from an extremely slow speed(under 5 mph). At highway speeds the transmission down shifts and upshifts just like it always has. My truck has 78,800 miles on it and has never shown any previous signs of transmission issues other than a leaky dipstick tube that I replaced about 3 years ago.
My father had a 94 Taurus that had similar symptoms in the past and it ended up needing new clutch disks and was rebuilt. I'm hoping for that rather than a new or reman'd tranny!

Have a 2009, 2500HD 4X4 23K miles that has an occaisional/intermittant trans slip when shifting from 2nd to 3rd (I think). It always seems to catch me by surprise so it may be 2-3 or 3rd to 4th. Shift point seems to be around 1800rpm, engine revs to about 2500 during the slip. It's always shortly after starting up and the trans is not necessarily up to full operating temp. I've noticed it happening in the dead of summer as well as the dead of winter.

After I change my oil, I need to reset back to "miles to empty" from "% left on oil" warning. 2009 F150, XLT Supercab. I do not know how to do this.

So for some time now my truck(2011) has a problem when I floor it while entering the freeway or even down the road..
If im cruising around 30 or 40 and floor it, it down shifts and takes off nice.. but when it goes to change gears, it chokes, not sure how else to explain it, but once past that gear, the following shift fine if im still on the gas..
Normal driving shifts ok, and if im going say 50 or higher and do the same thing, it shifts fine.. so its only when going slower and I floor it..
It has 69,000+ miles on it

I have the normally aspirated 3.7 V6. The ownersd manual talks about the trucks computer telling you when the oil changes are needed.....But, at 6500 miles, bnothing has come through. I have not changed the oil yet on it. I feel this is a huge sin, but am not sure.....I was raised you changed the oil every 2-3 grand. But the owners manual on this truck says the computer will tell you when to. Should I just go ahead and change it?

I traded in my 2011 Lariat last month because I had quite a bit of problems with it in the short time I had it. I also didn't care as much for the bells and whistles as I thought I would when I bought it.
I got such a good deal on a new 2011 Lariat Super Crew, that I traded. Shortly after getting the new truck, I had to take it to the dealer for two dents that I found the first time I washed it. I didn't see them when I took delivery because it was dark. I had not seen the truck before that because they got it from another dealer to get the color I wanted. I also had problems with the radio buttons on my steering wheel and the sirius button on the dash not working at times, damaged trim around the left side of the windshield, a discoloration the size of a nickel on the console that I noticed when taking delivery, and a ticking noise in the engine . After the truck was in the shop for 3 days, I get it back without anything being corrected. Parts had to be ordered for the console and trim piece.
I took the truck back in 10 days ago for the engine noise and for them to repair the dents that were there when I got it, along with more troubleshooting on my intermittent problems with the radio and steering wheel buttons. I get a call late yesterday afternoon with the verdict.....Ford says replace the engine due to something being wrong with the crankshaft.
I have to say, I'm pretty disgusted right now. I'm not so sure that I want this truck anymore because of all the issues I've had in the short time I've owned it. Service department at the dealer has been great, and the dealership has been talking about possibly getting me into a new truck. I'm just not so sure I want to try a a third truck. I've been a Ford man my entire life, but I'm disgusted with them right now. I certainly don't want a Chevy or a Dodge, so I don't know what I'm going to do at this point.

I wanted to change oil at 1000 miles on my new 2010 FX4. The dealer said that I should wait till 2500 miles or so because it still has the break in oil in it.
Does he know what he is talking about or should I change it? He did say he would change it and take my money if I really wanted to.
Maybe my thinking is still old school about changing the oil right away with a new engine.

My truck just hit 110k on the clock, and i've never had the transmission fluid changed. Is this something that I am past due on changing or early? I don't know when it is supposed to be changed. If so is it something that you can do yourself?

So last night on my way home I was stopping at a traffic signal and noticed a grinding noise from the drivers side front wheel. Upon further investigation I noticed a lot of brake dust on my wheel. I took it to the dealer thinking the caliper might be seized up. Well they looked at the caliper and said it was OK but the inside pad was worn to the metal. The other pads still looked good but since they have to replace the rotor they might as well replace all of them. The tech told me that being up north where they use salt corrodes the pads and doesnt allow them to move freely. He also asked me if I drive a lot of highway miles and I said yes, 30 miles a day. I guess from what he said is that the less they get used the more they will corrode up. So premature brake pad wear could be worse.

Brought my 2011 Limited (6.2 so old school hydraulic power steering) in for its 45K service, and they found a weeping high pressure line. $100 special order part + 3 hours labor. This seems a little soon (to me) for PS components to be failing already, or is this a common repair? They said I could leave it alone for now and monitor it but could lose power steering while driving (safety risk).
Any history of high pressure power steering line leaks at such low mileage/age before? Does 3 hours labor sound about right?

Having intermittent clunk felt in the steering wheel? It happens at random and not necessarily over bumps. You don't hear it as much as feel it in the wheel.

My 2010 has 11,000 miles on it. Was driving 75 mph down the freeway when the engine stopped. I was headed to the gas station as my low fuel light had just come on (at the time it died, 37 miles to E).
This is not my first Ford. I understand you shouldn't allow your tank to get that low because it is bad on the fuel pump (or whatever). But, I drove my 09 many times well below 37 miles to E. I have driven this vehicle below 37 miles to E. So, I was startled when it died.
It was towed to the dealership and their diagnosis was that it was out of gas. This does not make me happy... as I am aware that it was "low" on gas. But if the gauge is telling me 37 miles to E, then why did it stop running?
What good is a gauge/warning on my new vehicle if it is inaccurate?

The passenger front speaker on my 11 FX4 has been intermittent for a while. I replaced the door harness as described in TSB 12-11-4 but found the harness may not have been the cause. I have aftermarket speakers in my truck and installed them using Metra speaker harnesses. When pulling the old harness out, I found the connector for the speaker to be full of water. This is likely the issue with my truck but I wanted to share this observation with others who use these little harnesses. These connectors are not assembled using rubber grommets between the leads and the connector housings, which are necessary to make the connection weather/water tight.
Metra 72-5600 Connector - No Seals
Ford's Door Wiring Harness - Wire Side - Wire Seals
Ford's Door Wiring Harness - Connection Side - Blue Seal
Now, I'm just passing this along in the event others are experiencing this issue and also have aftermarket speakers. Before hitting the dealer up for the TSB repair, check to see if you have the same issue as I found. But if you're running factory speakers and have intermittent speaker operation, hit up your dealer for the TSB repair.

Experiencing cooling problems with a truck this new? My 2 month old supercrew 5.0 began over heating on a road trip last week. After about 400 miles of driving I see coolant temp start climbing until the overheating warning popped up. Pulled over, turned engine off, popped the hood and did not notice any obvious signs of overheating. Ended up waiting about 15 minutes, started truck up again, temp gauge reading 1/2.
Get back on the road, within 5 min temp starts climbing again, reaches ~ 3/4 then all of a sudden returns to 1/2. Continue on 10 min later temp gauge climbs from 1/2 to overheating quickly. I pulled over again same situation no obvious signs of overheating, but allow sometime to cool off. Started truck again temp gauge reads 1/2. Continue driving and temp gauge seems possessed, going from 1/2 to 3/4 back to 1/2 to almost overheating as I nursed it to the next dealer that I could find.
Dealer tech was able to mimic the problem and believes that coolant is not flowing properly. Thermostat replaced, water pump pulled and inspected, air bleed out of the system, all with no improvement. Now heads are being pulled/replaced to see if this solves the problem. Its depressing to have my new truck with 2,382 miles sitting under the knife at the dealer.

I've noticed an intermittent clunk which occurs when engaging the hydraulics brakes during reverse maneuvers. It happens with anything from very light to very heavy brake force and typically will happen before driving very far (backing out of driveway, out of parking spot, etc) but does not happen after driving (backing INTO driveway or parking spot). This has been occurring for a while now with no other symptoms (other than some shudder during take off which I attribute to a sloppy transmission bushing).
Front brakes were in great shape when I r&r them a while back to turn the rotors, didn't pull the rears apart but they look good, and I don't have any brake vibrations or issues when moving forward. I can't rule out a driveline clunk or suspension clunk either but the u-joints don't have any slop in them and no squirrely handling issues either.

Intermittent chirping noise when accelerating from a stop. It sounds like a brake chirp but it comes and goes. Not brakes. Changed pads and turned rotors chirp is still there.

For the last few months my truck has been throwing an intermittent check engine light due to the same code every time - P0171. The dealer has allegedly checked everything and has given me the "We have done all we can do" speech. Lead tech even suggested that since today's fuels have alcohol in them, that a check engine light would be normal. The truck has been in the shop 3 times with no success or even remote possibility of what the problem could be.
The check engine light has since gone from intermittent to constant and comes back on after 5 drive cycles after clearing with an OBD2 scanner. Also, I'm now getting a P0174 code.
Personally, I think they're trying to blow me off because I'm a few months and about 2k miles away from being out of CPO warranty.
Truck is a 2013 F150 Super crew 2wd 5.0 with about 45k miles.

I have absolutely loved my 2011 F-150 8 cyl since I bought it in 2013. I'm just now having my first issue...
For the past two weeks or so, I've had an issue with intermittently hard starting. It cranks like normal but doesn't turn over instantly. The longest its gone before starting has been about six seconds. Although originally happening only 10% of the time, its happening about 40% of the time over the past couple days. I had my mechanic take a look and the battery and starter all checked out fine.
Biggest problem was that it never did it for them making it hard for them to trouble-shoot. Thus far its always started, just takes an indescript amount of time in which to do it. The time of day doesn't seem to matter although afternoons in which I'm heading to lunch after being in the office for 3-4 hours seems the most common time.

I have a 09 Honda Accord manual transmission V6 with 59K miles. Recently, it seems to stick a little going into 3rd gear - only third. Called our local dealer's service department who said I should have done a drain and fill on my transmission fluid at 30K miles. I have driven manual transmissions for 30+ years and have never heard of this - but this is my first Honda. The owners manual is not very specific about this maintenance recommendation. Did I create unnecessary wear and tear to my transmission or is my dealers service tech just working to humble me?

I have a new 2011 F150 4x4 6.2 liter with about 1200 miles, 6R80 6 speed Transmission. I haven't liked the shift quality since buying a little over a month ago. I think the upshift from first to second is kind of rough and it feels like it's slipping a little from second to third gear. I've read a lot of negative posts/reviews on the 6R80 transmission, and some people have said it got better over time, or it got better with more aggressive driving. I do notice it shifts better if I drive it a little harder. The build date according to the sticker is 4/11 and I don't think there are any TSB's for PCM updates for this year/engine/model. I'm wondering if I should bring the truck in now for the dealer to take a look or drive it for awhile longer to see if it gets better?
