Ford F-150 (2004-2008) :: Transmission Seems Like It Slips At Times
Apr 13, 2012
I have a 2008 Ford Lariat F150 with 53k miles. The transmission seems like it slips at times. Here's the scenario. When I take off from a standstill and going through the gears at a normal acceleration pace, say I momentarily lighten the acceleration pace then try to resume. At that point, the transmission seems to slip momentarily, then bumps back into the pull mode. It feels like there is slack in the drivetrain until it re-engages, or like the lockup torque converter momentarily releases until the computer has time to react to the accelerator positioner calling for more. One guy said the transmission is, at that point, between two gears... either trying to decide to downshift or to upshift, but you can feel the surge in rpm momentarily until it decides ... then bump and your off and running again. If I push the O/D button, it stops doing it. What I can do? Because the dealer can't seem to get it to act up when they test drive it. It does it fairly regularly on me though.

My 2005 4.2 L transmission slips in overdrive but I turn off overdrive and it stops slipping instantly. What could be the reason for this does this require an entire trans rebuild or is it an easy fix.

I have a 2004 XLT supercrew 4x4 with about 150,000 miles with the 5.4 motor. I noticed that when entering an interstate at around 50-55 mph it feels like the tranny slips. There is a jerk, jerk, jerk than it stops, it doesn't do it at any other speeds and only getting on interstates. Runs fine in town. No lights on the dash or codes, fluid level is normal and clean. I did have a caliper sticking but it was replaced and it's still doing the jerk, jerk, jerk. Could it be U joints?

I had my tranny rebuilt under warranty at about 70K and I'm now at 167K. When it was rebuilt (by Ford) it still had a slip feel when I picked it up. Rode the mechanic around the yard and he felt it. Dead stop and take off while turning. Like from a stop sign. He took it back and found a sensor/module/something that was the culprit. Seems I remember they found it with a computer? Is there a computer/reader that will diagnose a tranny?

Friend has '04 LS and he says that after a heavy rain, his LS will only go about 25 mph. Water is getting into something but where? This lasts for about 2 weeks and then all is OK. Water is finally evaporating, I assume, and problem goes away.

The transmission slips a little when first driving after startup. After about two minutes it's fine. How to check the ATF? Also where to add and what kind. The owner's manual has no ref. to this.

I have a 2000 Honda Accord, 4 cylinder, automatic transmission. Transmission slips in reverse when backing up a slight incline. Will changing the transmission fluid solve this problem? The car has 115000 miles on it.

My transmission started to slip badly and I stopped it immediately and found transmission fluid in the radiator and nothing in the transmission. We replaced the radiator and flushed and refilled everything. It runs great now except it is vibrating every now and then. I'm wondering if the vibration is from running the transmission dry.

I bought my 2008 Chrysler 300 used at a car auction and its been running fine for the past couple years. About two months ago the transmission needed repair so I took it out and took it to a mechanic to get fixed. All i had to do was install the transmission back into my car. My car was still running when i took it to the mechanic. Once I picked it up from the mechanic i have been installing and uninstalling the transmission several times and yet my car still won't turn on. I don't want to have to buy a new one...

For the last little while I have been having an issue with the 4wd in my 2006 F-150 with about 93k on the clock. Sometimes it would engage when I switched to 4H/4L and other times it wouldn't. A friend of mine works at a Ford dealership and said it could be the vacuum solenoid on the firewall going bad. So I bought a new one and as I removed the old one, noticed debris in one of the inlets. So I cleaned that out and neither old or new solved the problem. Then I went through ALL of the vacuum lines and found some debris in parts of them....
Cleaned them all out and still nothing. Then I got to thinking it may be the ESOF motor on the transfer case. Checked to make sure there was power to the plug, which there was. Removed the motor and turned switch, and the motor seemed to be working. Reattached the motor and the 4wd would engage/disengage without problem. Pretty much everywhere I went I would check it and it worked fine . Then all of a sudden it didn't . So I took the motor off, turned selector and it worked fine. No issues yesterday at all.
So, I am not sure if it is the motor going bad or not. Could there be a contact problem? I talked to a mechanic this morning and he told me to drive around with it in 4H for a while because more times than not it doesn't get used enough. I'm just not sure what could be going on...am I missing something?

I have 2006 single cab stx and the little orange airbag guy below the speedometer has been on over a year and a half and he always flashes a code 51, but I've never worried about it.
About a month ago I started occasionally getting the 5 beeps 5 times, and now it does it more frequently but not every time. The Passenger Airbag Light above the radio works properly. It comes on when I start the truck and then goes off. When I put weight on the seat (usually my Jack Russell who only weighs 14lbs) it turns on and stays, and if the seat belt is buckled with no weight it also stays on. This is proper function correct ?
I've tried things I've read from replacing or cleaning up the crash sensor in front of the radiator, even cleaned the connections under the seats with contact cleaner, pulled fuses and none of them are blown. Are the code 51 and the beeping alarm somehow connected ?

So our 2006 f150 fx4 has been having an issue with stiff steering... at times like it doesn't have power steering at all.
We recently had the lower ball joints on both sides replaced. Before that the upper control arm on the drivers side was also replaced.
There are days that it is better... other times not so much.

3 months ago.. I had my fan clutch replaced, along with alternator.. a few coils.. a belt and an oil change. While installing fan clutch the shop accidentally poked a hole in radiator so they got a new one ( After Market) and replaced it. After leaving the shop, I noticed the fan clutch was not rotating smoothly, it had a considerable wobble to it, so took it back and it was replaced..new one did same things.. so it was replaced again. Truck seemed fine after the 3rd one was installed, and then after a a 3 hour drive.. i pulled over to gas station, and while truck was at idle in park.. it started to run hot. Raised hood, there was no visible coolant in holding tank on side, so after a while.. i took cap off and as I released it... coolant started to bubble back into holding tank. I then started truck up.. it was fine rest of way home.
Over next few weeks, this happened 4 times.. ac will be on, truck sitting still at red light etc.. and truck will start to run hot. So i had a new thermostat installed, and also a new water pump. Took it to a guy who runs a shop i know and also had system vacuumed. ( it was burped prior). Thought we had it fixed.. NOPE.. did it again yesterday. So truck has had new fan clutch, new thermostat, new water pump, new coolant, new radiator.. and it still only runs hot if at idle.. and it wont do it all the time.. but about once a week.. it will... and it will go over to red.. and ill shut it off and after about 10 min.. turn back on and continue on my way.. What I noticed..and this may be a key piece of info to someone who may know what is going on... it seems that the times it has ran hot.. while at idle the fan clutch was off.. and once i reved engine up to 2500-3000 rpms.. I got clutch to engage and bam !!.. truck comes back down to normal temp.. midway on gauge .. AS long as I am driving down road.. no problems.
** Also as a sidenote.. my engine does have a engine coolant temp sensor on it. Part # DY 1025 motorcraft. On some vehicles.. this part tells the fan when to turn on.. not sure if it does on mine. Originally , I took truck in bc fan clutch was staying engaged to much..meaning fan was on all the time. So.. maybe it could be the sensor ?... now all the new fan clutchs that have been put on do not come on like they are suppose to.. work right sometimes.. other times.. truck has to be at high rpms to get it to engage.. not working right all the time at low rpms.
Are their fan clutch relays ?.. I have an electric fan clutch.. This seems to me that this is a fan clutch issue.. and this is the 3rd one on the truck.. came from autozone.. it is the correct one for truck and has a warranty. Mechanic now wants to try going with a ford fan clutch by motorcraft.. 2007 F150 5.4 V8 ...

I have a 2002 Ford Escape 4x4Automatic with 97K on it. It has just started slipping in Drive. It will go in reverse just fine. If i put it into 2 or 1 it will take right off then I can move it into D but only with the OD off. If it is on the engine revs and you don't go anywhere. I have no lights flashing or bells going off. The fluid is clean and doesn't smell burned. Is my transmission toast? Is there a chance I can have it fixed cheaply or even do it myself?
Here are the symptoms once again.
Moves in Reverse.
Revs in D with OD on or off
Moves in 1 or 2 with OD on or off
When you get it moving you can put it into D with OD off and get 3rd gear. If OD is on It just revs.
When you come to a stop in D with the OD off and try to take off again it just revs. You have to use 1 or 2 to get moving again.
Will the car make it 300miles home so i can have it looked at?

I've been having this occasional starting issue with my truck. I turn the key and the engine acts like it's going to fire up, so I let go of the key and it doesn't start. Then I try to restart it and either it cranks and fires a few times before it starts, or it fires right up and the starter grinds because I couldn't let go of the key fast enough.
I've had this problem a few times before, but lately it seems to be happening more often. It works normally 98% of the time. Maybe I'm just not letting the engine crank long enough to get it to run before letting go of the key.
Also, the spark plugs were just changed 10k miles ago and when the truck is running it runs great.

I have a 2007 F150 with a 5.4. I am having an issue with my A/C and more.
Here are the symptoms:
1) A/C doesn't blow cold, at times.
2) Compressor not coming on, according to mechanic.
3) Engine sounds like a freight train, at times. Like on a super cold day and it has to work hard.
4) Very poor fuel mileage since this started.
I took it to a shop, and they said it was the engine cooling fan that would not come on. So I replaced it. Same issue. I then took it back and was told there is a wiring problem. After 3 days they couldn't find it. I needed my truck back and dropped it off again. Then they said it was the A/C compressor, maybe. They wanted to try it and then see what happened. I told them no way.
Temperature, according to the gauge is good. Noise comes and goes. Not dependent on anything. Weather, temperature, car heated up or dead cold. Just comes and goes.

So I recently bought a 2006 f150 XLT with a 5.4 and of course the previous owner failed to tell me that it has an annoying beeping problem. It chimes 25 times total about every 20 minutes of the truck running, I've read the owners manual and found that it could possibly have to do with the passenger air bag.

My 2005 150 4X4 made a "clunk" noises several times when in 4 wheel this last weekend.
Sounded like the transfer case wasn't fully engaged.
This was after doing numerous 3 point turns on a dead end road to turn around. A real nightmare, cliffs on one side mountain on the other.
when we got back to relativity flat ground it ran fine with no more "clunking" noises.
It has 95K of hard miles on it. We didn't want to get stuck out of cell phone range, so we headed home.

My wife has a 08 F-150 LIMITED and at random times gets a raw fuel smell through the air conditioner ducts. It will happen after we fill it up and it will happen @ a 1/2 tank. No smell under the hood and no visible leaks from anywhere. Pretty important issue to me.
