Ford Super Duty (1999-2016) :: 2008 F250 - H&S Tranny Rev Up While Accelerating - Slipping?
I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

2011 f250 gas 4x4... I bought last year with 65k miles, now has 105k. sometimes when accelerating it slips for a second like a manual would if you jabbed the clutch while pulling. I had the 100k trans flush done. I noticed it a couple times before but more frequent recently. How concerned should i be?

My husband and I bought a 09 f-250 with 58000 miles. It used to pull our travel trailer with no power issues. Now the rpms go up & the power goes down. It never gets hot nor any lights come on. It's been in the shop twice. The first time nothing was found. The second time we were told it was dirty fuel filters. The truck only has 70k miles...

We have replaced 4 fuel pumps on a row.
Voltage is good...even ran a fresh circuit.
Ran new supply lines
But, can't seem to understand the continued drop in pressure. It usually takes about a day of driving to crater after a new pump/filter is installed.
It never dies, just loses power and drops the truck to an idle. Funny thing...if I shut the truck off and turn it right back on...full power for a short period!
The truck is used on a ranch that has plenty of rough roads...thought inertia switch maybe but i believe that would stop fuel completely right?
I am totally stumped and so is the mechanic.
Ford Super Duty (1999-2016) :: 2006 - Tranny Slipping While Towing Uphill
'06 Power Stroke/136k miles.
This last weekend I was towing my rzr up hill and the tranny slipped, lost power, and the "Wrench" check eng came on. I pulled over, checked my fluids, checked for leaks, checked for smells, couldn't see anything visibly wrong.
Turned it back on and no other issues on the way to the camp site. On the way home, days later, same thing happened twice. Is the tranny going bye bye? Would it be worth it to get a flush for the possibility it just may be the fluid and maybe some sediments or something of the sort?
AND the bigger question is, if it is the tranny, should I trade this POS in, or replace the tranny? It has had a few problems lately with the turbo. Needs a new AC compressor. I didn't do much homework or know about the 6.0's before I bought this truck. After I bought this truck last year I heard about all the problems the 6.0's have and wished I would have went another route.
I can turn a wrench pretty decent (Aircraft Mechanic) but I have very little knowledge on vehicles, let alone this POS. I am apprehensive about doing a transmission or any big components without assistance. This is why I am trying to decide what the best option would be for the long run.
Ford Super Duty (1999-2016) :: 2011 F250 - Power Mirrors Not Folding In Or Out
How to disassemble the power fold mirrors on my 2011 F250.
The mirrors work in every way except they will not fold in or out. You can hear the motor start but then stops right away. It does not sound like the gear is stripped just that the motor is stuck some home. It happened to both mirrors about the same time.
I was going to take one apart and see if there is a issue. I can't see there being a electrical issue, but maybe, since the driver side starts then stops within 1 second. It's hard to tell about the passenger side since the switch is on the drivers side.
Ford Super Duty (1999-2016) :: 2011 F250 - Braking Power Dropped
So yesterday I drove across town and back to pick up a piece of lawn equipment. About a 30 min hwy drive each way. On the way there I was in stop and go traffic for about 15mins and noticed toward the end the truck would pull hard to the right when stopping hard and sudden. I figure it was my steering. Been having issues with horrible steering since my last alignment and adjusting the caster. Truck wanders, steering feels loose, will not fully recenter, and feels like it binds then releases toward center position. That's a different issue, I assume. I stop on the way to get some cash and everything is normal. Pick up the equipment and drive back. When coming to a stop the truck will pull towards the right and when I suddenly stop it now pulls to the left.
I get home and get out and smell something burning and hot. Grabbed my IR thermometer and hit both front wheels. Passenger is 150f brake rotor is 175f, drive is 280f brake rotor is 580f. So im assuming my caliper seized up or started to stick. I plan to jack up the front and look at the hubs and calipers. Any other test I can do to narrow down the culprit. I am thinking the hoses may be collapsing especially since I had to disconnect and flip them during the lift. Just weird that the hard pull would switch sides if only the drivers was sticking. Could my bad steering and brake issue be related? I have also noticed my braking power has dropped recently. Brake fluid looks good but power steering smells like brake fluid and is orange.
Pulled the tire when I got home today. A little resistance when spinning by hand, more than there should be. Pulled the caliper and greased the slides. Found out my hub is bad so those are on the short list now. Reassembled and had my wife hit the brakes while I spun the tire. Progressively got harder and harder to spin. Was looking at the brake hoses, how much should they move and ''shrink'' when the brakes are applied? Also if I hit the brakes repeatedly while rolling down my drive way the pedal gets harder and the truck doesn't want to stop and the pedal will slowly push all the way to the floor. Now I am just lost at what is causing my braking issue.
Ford Super Duty (1999-2016) :: 2001 F250 - Tranny Started Overheated
So out of nowhere, my tranny started over heating. Got up to 210. It usually runs in the 140-150 range. I have the 6.0 cooler, and 7500 miles on the synthetic fluid. My cooler lines to the radiator were ice cold. I crimped my bypass and this seemed to fix it a little (I know this is a no no), I did the flow test before driving it and it passed. It seems to heat up the most at stop lights in gear. It drives fine, no slipping, no chattering. I also dropped the pan, had some stuff on the magnet, replaced the filter too. It doesn't seem to heat up as bad now, goes to about 190. I will install the new bypass tomorrow when it comes in from the ford dealer. Whats causing the heat? BTW truck has a 4" lift with 35's no other mods.

Got the truck 2 months ago and it only happened 3 times; always on a cold engine.
2 times were on my street at low speed just out of my driveway. It's like the engine shuts down for a while and maybe downshifts too. Feels like someone is stepping on the brakes for a second and then all is back to normal.
Last time I was getting out of a restaurant and accelerating hard to get up to speed on a 70km/h road. The downshift happened while I was going almost 70 but still in low speed so the braking effect was severe enough to throw me forward. Once again everything was fine the next second.
I'm not sure if it's the transmission downshifting or the engine cutting; maybe even the ABS kicking in for some reason. It happens too fast and too rarely to be sure. My feeling from what I remember is that the truck is downshifting and I'm feeling the braking effects from compression. 6.2 engine.
Ford Super Duty (1999-2016) :: 2008 F250 Transmission Slipping When Doing 55 MPH
I been having a issue with my truck lately. It's a 2008 with only 88,000 miles. When doing 55mph it feels like the transmission is slipping. Sometimes it will do it over and over. If I speed up to about 60mph it goes away.its has gotten worse in the last month or so. Hoping it's nothing major.
View 6 RepliesFord Super Duty (1999-2016) :: F250 - Transmission Fluid Is Low / Slipping
1999 F250 SD... Tranny fluid is low, tranny slipped one time on me. I checked the fluid and it's low. No drips on the garage floor, so I'll have to inspect closer. But my question is can I add new fluid without screwing it up even more? It's got 170,000 miles and I doubt the fluid has ever been changed. I just bought the truck last week, so I can't say for sure, but it hasn't had a regular flush or change. It doesn't smell burnt but it's just a little darker than new fluid. I was told by the guy I bought it from that the torque converter was changed in it not too long ago.

I have an intermittent problem with my 09 F250 Diesel. A few times now under hard acceleration I have had the trans seemingly get stuck in 3rd gear. The little service required wrench symbol showed up on info screen but after shutting off the engine no codes were present. A week or 2 later this happened again and I ran diagnostics through my Spartan tuner and got P0771 and P2704 for codes.
Again they cleared when I shut the engine off. Since this is an intermittent problem, only after hard acceleration, would it make sense to change tranny fluid, maybe do a tranny flush? Or am I off to the dealership for a rebuild?

Ford Super Duty (1999-2016) :: 2005 F250 - Transmission Slipping Going Uphill
I bought my F-250 Super Duty 6.0 last October, and I am extremely happy with it comparing to my former '03 Dodge 2500 TD. The Ford drives so much better!
There is only one problem I have with it. Without pulling it shifts nice and has lots of power. A Month ago I bought a fifth wheel trailer and I hardly notice it behind the truck, also it doesn't use more diesel pulling. However going uphill the transmission seems to slip, and I can hear (sounds like) a fan running loud? I loose speed.
All the temperature gauges stay normal, no difference. It starts to pull worse. I replaced de tranny filters, inside and the outside one. Also I did put the correct transmission fluid in there, no difference. Almost no grindings in the oilpan/magnet.
I looked on many sites, but cannot find anything on this. Personally I think it's the torque converter? My final step would be to have the transmission rebuild, with the best parts available, (close to WA, ID, MO)...
Ford Super Duty (1999-2016) :: 1990 F250 E4OD Tranny Would Seemingly Go Into Neutral While On Freeway
I have a 1990 F250 with a 7.5 liter and an E4OD. It starting acting up a couple months ago. Tranny would seemingly go into neutral while on freeway. I figured trans was going out... After reading several threads I've decided to try changing the mlps first, got a new one at the dealer!!!. It is the updated one with the connector on the top. I'm currently waiting on a new pigtail from autozone (the original is in bad shape, wires frayed, insulation missing. Also I think when it started having issues we were having some serious rains, which may have caused this connect to get wet.
I believe a previous owner may have had the trans rebuilt at some point. The connect has 6 wires going in it and when I trace those wires back, two are spliced into one farther up the harness a bit. Looks like one is tied into a wire that goes to the solenoid harness. I'm hoping I can cut and splice the 6 wires into the new pigtail and be good.
For now, while I was under there I decided to pull the solenoid plug as instructed to make access to mlps plug easier... the lock is on the backside almost impossible to get to, I messed the plug up all the way around, but not fubarred. When I pulled the plug out, it was soaked in transmission fluid... Is that normal?
Ford Super Duty (1999-2016) :: 2015 F250 - Cold Tranny Noise / High Rev Sound When Accelerate
Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.
Ford Super Duty (1999-2016) :: No Power From Tranny
Yesterday wife left driveway and about a block away she phone truck "died". It actually starts and the engine is fine - shifting from park to reverse or any gear seems to have no effect. After tow home - i check and there are no codes (using ODBII scanner), the tranny fluid seems full and red. Looking carefully there is a slight rpm drop when idle into reverse or a gear other than neutral or park... but revving engine in any gear doesn't move the truck.
Is there anything else i should check before taking to a tranny shop? Its a 230k mile workhorse for the house but not critical if its down for a week or two. I have had it for 10 years and put the last 40k miles on it. Is there any diagnostic suggested given the symptoms?
Ford Super Duty (1999-2016) :: 2007 - Deceleration / Hesitate And Loses Some Of Its Power
I have a 2007 6.0L 4x4 it has 225k on it. I just had it into the dealer this past week (which we just purchased end of June) they replaced back pressure sensor and #7 injector. Now when you get to about 70-75 on incline it is decelerating and hesitate and looses some of its power.
View 4 RepliesFord Super Duty (1999-2016) :: OD Light Flashes / Truck Loses All Power
I have a 2001 250 Super Duty. I am having an intermittent issue with the electrical system and transmission. I don't drive this vehicle very much so it sits for 7-14 days at a time.
Previously I had the od light flashing and had the transmission solenoid replaced. A few weeks ago I decided to drive it to the corner store. As I arrive home the od light starts flashing and the transmission starts shifting funny. I pull into my parking spot and turn the truck off. I sensed the shut off was weird so I tried to start the truck. NO POWER! None! I go back to the truck a few days later and it starts up without an issue.
Approx. 20 miles later it starts again. This time I have to jump the battery. I ran the truck and it drove without issue. Again a couple weeks later it starts in again with the light flashing and electrical dying. What it may be? I'm probably going to get rid of the truck as I can;t justify to myself to keep dumping money into it.
Ford Super Duty (1999-2016) :: 2001 F250 - Trans Slipping Accompanied By A Sound Like Hitting A Rev Limiter
I have a 2001 F250 SD 4x4 5.4L . I purchased the truck used with about 120,000 miles on it. It runs great despite averaging about 10.8 mpg. Shortly after I got the truck, I noticed what I thought was an intermittent transmission issue when the trans would shift. I would get a "flare" that lasted briefly as if the trans was slipping, but it was accompanied by a sound that I'm not sure how to describe, but it was somewhat like hitting a rev limiter. It only happened when the transmission shifted. The fluid was clean and did not smell burnt. I assumed it was a misfire issue, even though it did not happen often, and seemed to only happen at shift points. I changed all of the plugs and all of the coil packs. It still does the exact same thing. Sometimes it only does it once every couple of days, and other times it may do it 3 or 4 times a day.
