Ford F-150 (2004-2008) :: Transmission Slips When Entering Interstate At Around 50 - 55 Mph
Feb 17, 2016
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 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.

2007 F150 King Ranche 4wd 5.4 192000 miles.
I started noticing a little stutter when trying to hold 45 mph if I hit a mild incline, and also at 70 or so if i hit an incline.
Around the same time, I noticed that acceleration seemed sluggish when getting on the interstate. Gas mileage dropped from 16-17 mpg combined to 12-13 mpg combined.
Historically, since I bought the truck 3 years ago, if I go WOT to get up to highway speed (Not my normal mode of driving, more of a test) I would get a misfire on cylinder 8.
About 2 weeks ago, driving around town, I got a check engine light. The code said it was rich on bank 2. Cleared the code, it has not come back.
Here is what I have done:
Flushed the tranny (Vehicle history shows this has been done consistently since original purchase)
Changed all 8 plugs (none broke!) and all 8 COPs. - Fixed the misfire on cylinder 8.
Still sluggish and still have the stutter at 45 and 70 on an incline. I know it's not a racecar, but 0-60 in 19.6 seconds seems quite unreasonable.
New Fuel Filter
New Air filter
Cleaned MAF sensor
Had the back pressure on exhaust checked. No blockage there.
My torque app tells me the TPS is functioning normally.
No codes are being thrown, no CEL at this time.
What am I missing? I have a reader that will chart up to 8 sensors as I drive.

Today I was driving on the interstate at about 70 mph and my truck seemed like it popped out of gear...no loud noise or anything. I was able to coast off the off ramp and my truck was still running but sounded a little odd when I revved it. No gears work and when i revved it in gear it sounded like something loose in the bell housing area maybe. After I turned it off I was not able to restart it, sounded like the starter was just free spinning. Flywheel maybe?

I noticed a slightly rough ride around 70-80 mph sometimes on interstate a month back but thought it was my scalloped tires that need replacing and ignored it. Last weekend i had to go to MI from GA pulling a small enclosed tandem axle trailer (6x12). I started after work and made it to VA before stopping for the night with no problems not even at 70-80. Fueled up first thing in the morning (BP Fuel) and headed farther into the mountains when the truck started shaking when it should be downshifting (into overdrive I am guessing?)
No check engine light come on so i pulled off the road checked rear end and motor oil everything was fine, topped off tranny which was slightly low but was on dipstick .I let the truck cool for 20 min then got back going again. I continued driving with overdrive off, and not on the truck. Every time it had to downshift under hill climb it would start shaking but i would let out of the gas and it would stop. Once i got out of the mountains it was fine and couldnt tell it was running bad at low rpms, and also drove fine when i got off the interstate for fuel driving in towns.
I drove that whole day through ohio mich and back trough ohio when entering kentucky. It started to downshift and run at high rpms with no problem, and started acting up when i got back into the mountains.When the truck would go to downshift it started to shake uncontrollably again. then is when the check engine light come on and flashed. I babied in until tenn when i stopped at oriellys to hook up to scanner. scanner read misfire on 5 and ignition coil d primary secondary circuit malfunction. I checked the #5 plug (fine) and replaced the #4 coil, and didn't check the #4 plug.
t kept going and it never fixed the problem. stopped and jumped my coils around and check a few more plugs which all were fine but never that #4 (why idk), after being fed up, sat night, no mechanics around and wanting to get home i drove it the rest of the way. it never idled rough until i got almost home in Ga. When i got home the next day i pulled all plugs and all looked brand new still except the #4 which had the whole prong and tip completely burnt off. I replaced it and nothing changed, but my exhaust sounded restricted. Brought to a shop and it is now reading a misfire on 4 (with brand new plug) 5 7 and 8 and also saying it is running lean. They changed fuel filter and plugs but nothing still.

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 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?

When my Excursion sits for a while, the transmission slips a lot at first till it builds up pressure. Is this a problem? It seem fine other than this.

'96 Explorer 4.0l V6 4X4... 214,000 miles. So, I'm having some transmission slippage and was wondering what can be done about it. You see the mileage and the only thing done to the trans was a drain and filter/fluid replacement at 120,000 miles.
Here's what's going on... When cold, in the morning, I put it in drive, trans engages, I move maybe 20 feet and it disengages. I wait up to 20-30 seconds and it engages and slips right back out. I wait, engages, move 50 feet and it disengages. You get the picture. After doing this 4-5 times it will engage and I can drive a 100 miles with no problem. Seems like it need to build up pressure or warm up before it will drive normally. I've checked the fluid and it is at the correct level. I guess my question is, would I be wasting time and money to replace the filter and fluid again or is it just warn out?
I've read when a trans starts slipping after it's warmed up means it needs a rebuild and mine is the opposite.

finding out what is wrong with my Taurus. I have searched all over the internet not finding any posts about a similar problem. When driving after I turn past a certain point only to the left not to the right. The car slips into neutral revving, then once Ive straitened out somewhere along the wheel turning radius it re-engages in gear and lurches forward. The car drives fine and shifts smoothly except this.

I just recently bought a 96 XLT 4WD Aerostar. It's got about 158,000 miles on it. It's got a few problems I wanted to ask about.
1. When I'm on the highway, once I reach about 82 or 83mph the transmission seems to slip into neutral. Does fine around the city and every other speed on the highway but once I pass 82mph it slips and revs really high. Could it be the torque converter?
2. Clicking while turning sharp and reversing while turning. I figure it probably needs new cv joints?
3. The gas mileage seems terrible. I still have my Ford Econoline 250 and that seems to be getting better gas mileage. What might cause the mpg to be as bad as 12mpg on the highway?
4. The speedometer goes nuts after about 40mph. Is that an easy fix?

I have a 78 f100 2wd, 300 inline 6 and I've put 2 c6 transmissions in it. The transmission shakes real bad in reverse. When you put it in drive and try to take off it wants to quit pulling but when you put it in first gear and shift up to 2nd it works perfect. My plan was to just junk the C6 and switch to a manual trans but I don't know what trans I would swap it with.

The C6 in my truck is acting odd.. its into drive by 17 to 21mph under light throttle and under moderate throttle it slips occasionally when shifting, the 460 had a fuel spurting motorcraft on it, had to swap that for an edelbrock 1406 to drive it. The kickdown is there but setup for another truck. I don't know if the c6 has a vacume modulator or if its all controlled through the kickdown rod.. it does need a fluid an filter change that's gonna happen this week.. this trans just has me leery with the soft shifts.. its in 2nd almost immediately after takeoff....

So a couple months ago I had a transmission problem. It shifts high and hard all times and after the "od" light gets going (after it gets warm), the transmission slips (like riding clutch) when starting from a stop. If I went from drive to 1st gear with the selector and back, it cleared the slipping problem for a bit. I did an oil/filter change and about 50 miles later the truck is running fine, no issues. One day I hopped in it to go to work and it was like nothing ever happened. Fast forward 1,500 miles later. I start to notice the transmission is subtly shifting weird, like a small jerk when shifting. It gets worse over 50 miles and now I am back to the above problem. Is there a way this could be a sensor or solenoid problem? I never heard of a transmission correcting an issue then starting at it again so much later.
I don't like fixing or working on an issue unless I am at least 95% sure what the problem is. I also don't have $2k to plop down on a repair at the moment. Would it be worth it to take this to a dealership and see what trouble codes I am getting? I would try a transmission shop but it's not guaranteed they will have the test equipment to check a ford transmission. Also a friend said that AutoZone and other stores can't check transmission codes. So what's the best option here?
