Ford Super Duty (1999-2016) :: 2001 - Slip In Automatic Transmission
Aug 26, 2017
A few weeks ago I noticed what seemed like a "slip" in my automatic transmission. Only happened a couple of times and I thought maybe it was just me imagining it or I didn't have the shift selector lever firmly in "D"rive. Then I went on a 4,000 mile trip pulling about 3,500 lbs. on mostly flat roads but it did include some 7% grades in the hilly parts... the truck performed flawlessly.
This is probably not related but ... after I got home, the truck sat for a few days and then I noticed a coolant puddle under the truck. Traced it down to what appeared to be a slow drip from a bad squeeze clamp on the large, lower rad hose connection. Replaced the squeeze clamp with 2 worm drive clamps and no leaking issue since.
Then last night, the tranny seemed to "slip". My short run across town started out OK. However, when I arrived at my destination, the diesel motor would rev to around 2500 rpm but the truck barely moved forward. It eventually did shift into second but also with high revs. It was the same feeling as if it were a manual tranny and you were giving it lots of throttle but only letting out the clutch a little bit (i.e. riding the clutch). This happened a couple of times last night. Also at a stoplight with the brakes on firmly, the truck was gently and rhythmically "rocking forward" as if the tranny was not fully disengaged.
When I worked through the gears shifting manually, the problem seemed to disappear and the truck responded going through the gears normally. Upon restart about an hour later, tranny shifted fine both in the city and at highways speeds on the way home.
B-I-L commented "sounds like your clutch is slipping". Not exactly sure what he meant as I had to leave. I'm hoping this will be a simple fix/adjustment and not the dreaded mechanical diode failure leading to a replacement tranny. Truck only has about 75,000 miles on it.
I'm suppose to head out on my annual vacation next week carrying a 3,500 lbs. truck camper and pulling a 3,000 lbs. cargo trailer with our gear. Obviously if the truck is sick, this trip can't happen. I know some of you would dive right in and start taking the tranny apart to repair it ... What is wrong with my transmission and what I should be doing next?

Drove the wife to work this morning. The turn off into town there was a lady stuck so I pulled over in the drifts. After putting in back in gear I had to get on it to get out of the drifts. Snow was blowing over the windshield, and I imagine throughout the engine bay.
After that it felt like it stayed in 2/3rd gear. I'd hit the pedal and it would redline and sort of accelerate jumping in and out of gears. So i slowed down to a stop. Accelerated slow and it was ok but when I got more on the pedal it would feel like it was slipping. Once I got in the driveway, she idled for about 15 mins while I shoveled out my spot. Once putting in gear again I had to rev it up for it to move.
Also reverse, had to rev it up to move it.

How can I tell if I have a limited slip in my '01 F250 4WD? I need to know if I need the additive for the gear oil.

I have a new to me 2000 F250 7.3 diesel with automatic. Truck has 185K miles and tranny is starting to slip occasionally. Do these trucks come with a OEM tranny cooler or do I need to add or upgrade the OEM one. Someone also told that there is something called "bulletproofing" the tranny on these trucks. BTW, what would be a reasonable cost to have a two wheel drive auto tranny done on my truck?

I have a 2003 f250 4x4 with a 5.4 motor the automatic trans is shot. I can get a replacement trans from 2000 f250 4x4 with the v10 motor. I tried my best to research it bell housing supposed to be the same so it should fit. But I'm not sure what they changed in those years internally or electronically.

I am experiencing what feels like a "bump in the rear" when initially starting from a dead stop. It feels like a car behind me tapped the bumper or that the truck "hunkers down" first, then moves. Tranny seems fine also. Once moving, there is no problem whatsoever. There atre no noises, leaks, or other symptoms. Also, when coming to a stop, it feels the same way just before the truck completely stops. If I drift forward a little, then apply the accelerator, it does not "slip" or hunker down.
Took it to the dealer and they claim that they can't find anything wrong and may just be the suspension releasing? The truck does this whether loaded or not?

I've got an issue...
Symptoms:
1. Sudden slip feeling(like you just hit a small patch of black ice while powering up a hill.)
2. Turbo Pressure still spun up.(According to gauge)
3. Backfiring out of the airbox. (Sounds like a flat tire)
4. Lose a bunch of power. (Feels like a car running on 6 out of 8 cylinders)
Only happens at mid-throttle, during a long uphill run while towing. Doesn't happen when not towing or first thing out of gate when engine is cool. No problems going downhill either.
Situation: Towing a 10k pound 5'er, to Yosemite, I would get this random sudden lose of power, that accompanies a series of backfires out of the airbox during a long steady uphill drive.
Truck has 161k miles on it. Fluids are all brand new. I didn't see any smoke coming from the tail pipe, like turbo was done and letting oil into the engine. Oh also, no check engine lights.

I have a 2002 7.3 with the 4r100 173k miles. If your nice to it she drives fine, but if you get on it the torque converter will slip/stall kinda revs up like 300 rpm then slams really hard between 1st and 2nd. Other gears work fine. I've only had it not happen like 10 times since I've owned the truck ..... I don't really beat on it except for towing which I'm starting to do a lot of. Wondering if putting a new stock torque converter in it is worth it.? Not gona blow the bank on a TC unless I'm putting a brand new trans in the truck. Which I don't think it needs in the near future.

I have a 2001 F250 V10,
So the truck drove fine yesterday had zero issues... I used my auto start as I do every morning in this cold weather, get into the truck and shift from park to drive and its like it does nothing. I can free rev in N,D,1,2. Reverse works great.
I tried switching from 4wd to 2wd, no change. Reverse works just fine. No noises, codes or anything, just doesn't want to engage...
I am assuming I have a 4R100. Could something electrical cause this? I am thinking its mechanical, but hoping someone has ran into this before.
Literally no way I would have known the trans was going bad... It's always worked fine. Tranny fluid is full, I tried unplugging the battery waiting and plugging back in, no dice.

I have a 2016 F350 Lariat. I feel the auto headlights do not come on soon enough. I have not talked to Ford yet, but am wondering if there is a way to adjust when the auto lights come on?

I have a 2001 F250 Super Duty 5.4 Triton motor with a Transmission Leak. I have drained the Transmission, replaced the Transmission pan gasket and filter. The auto parts store also had me purchase the Torque Converter bearings/seal along with enough transmission fluid and a bottle of Lukas Transmission fix. Do I really need to replace the bearings/seal if I have everything else already ?

My '01 7.3 is having some transmission problems, My O/D light is flashing. Trying to go after stopping at a light is a difficult, it drives very sluggish, like its not in overdrive. Scanned it and got three codes P0732, P0720, P0503. I replaced the ABS/VSS on the differential and the problem still exist.

I love the power folding mirrors on my 2014 F250 Lariat, really makes a difference in parking lots. Is it possible to make them fold automatically when turning off the vehicle? I know it is a lazy person question but with automatic seats and mirror/peddle position wouldn't automatic folding also be a good idea?

I have a H&S mini max. Controller and have installed the mild download and run on the street setting for every day and tow setting while towing my fithwheel, when I just took it out for a test drive towing the fit wheel going up hill it kept shifting up and down which sure felt like 3rd and 5th because rpm would go from about 3500 to 1500 back and forth so it sure felt like it was not hitting 4th, could this be a controller issue?

2006 F-350 diesel 4x4 ... Is there someway to disable the automatic door locks?
Truck is used on a construction site and every time someone moves it and then I need something out of it doors are locked. I hate having to try 3 doors every time until I remember to go to drivers door.

I have a 2008 F350 and my automatic hubs won't work, also when I turn the AC on there is heat coming out of one side of the vents. I am assuming this is a vacuum leak somewhere but my vacuum pump doesn't run steady? I thought if there is a vacuum leak then your pump should run steady? The 4X4 works fine by locking in the hubs

The other day I had a metal pin fall out from under my dash and hit me on the foot (only reason I would have know if fell out till I clean the truck)
Ever since then the gear selector handle for my transmission has become sloppy and when I go to turn off the truck, I have to hold the arm up to turn key off all the way. I have looked to try and find where it goes and cannot find the location. I have also looked at a blown up parts diagram and cannot find it. Where it goes?

I recently purchased an 06 F250 XLT Crew Cab. I want to add the factory automatic headlights to it. Is there anymore to it than the photocell and the light switch that I need to make it all function? I'm adding the factory driving lights and getting the automatic headlight switch with the driving light option. I tried the search function but came up empty.
