Ford 6.7L Power Stroke Diesel :: Tranny Slip And Lunge Between Gears


Nov 1, 2012

I'm at 5,500 miles and the last couple of mornings I've had my tranny slip and lunge between gears, sometimes 2nd and 3rd and once out of 1st. I know there's an update/flash that needs to be done but my build date says not required. My truck was finished April of 2012. I'm going to call the stealer but I'm sure they will "check it out" and say nothing's wrong so it would pin point this issue.

Ford 6.7L Power Stroke Diesel :: Truck Lunge / Surge A Little When Stopped With Foot On Brake

Experienced a weird transmission issue this weekend. Started truck up first thing in the morning, only a short warm up, it was about 50*F. Drove about 200 yards to the gate. Stopped with foot on brake while wife got out to open gate.

Felt truck lunge/surge a little. Thought that was weird. Then it did at again, but more like a double surge, jumping in and out of gear.

Rolled forward through gate then stopped again with foot on brake. It did it again. But this time I noticed the gear indicator in the dash jump. It was shifting from 1st, to 5th, down to 3rd, then back to 1st.

I pulled out my phone and was able to catch video of it doing it a few more times. Start about 16 seconds into video. Transmission Ghosts?

About 1:20 in I drive forward and it shifts to 2nd fine. I stop again at 2:00 in.... and it does it again around 2:30. Then it also flashed a "Check brake system" and "Service AdvanceTrac" message for half a second (around 2:44 in video).

After catching video, I drove the remaining 1/2 mile driveway to the county road and stopped again. It didn't do it any more. It did however flash a traction control off/on message for about half a second. Didn't catch that on video though.

Drove 12 miles to town to Ford dealer. Service Dept was closed (Saturday). It didn't do the shifting again for the rest of the weekend. Made the drive home Monday (140 miles) without a problem.

Dropping it off tomorrow morning at 7AM so they can try to fix it. They hope it stored some codes even though it never gave me a wrench light or other trouble light that stayed on. Hopefully it's a just a software glitch or a faulty sensor.

Ford 6.0L Power Stroke Diesel :: Transmission Slip Or Jerk In Drive Or Reverse?

I have a new issue that started last Friday. When I put the truck in gear and let it begin to pull itself, drive or reverse, it has a strange jerking or slipping deal. It doesn't happen every time but when it does you can feel it in the drivetrain. I took it to the shop that did the motor work and they ran a diagnosis(while I watched) on the motor and its turns up nothing. It runs perfect, shifts like it always has, but just has this jerking/slipping thing when I let off the brake and it starts to pull itself.

If I go from brake to throttle its fine. I had the rearend diff worked on to fix the leaky ring and pinion seal and the differential cover sealed at the dealer last month. I searched and don't see anything like what I am experiencing. Could my tranny be giving it up now? It has never been overworked and never overheated. I had the full fluid service done at about 70k and now it has about 130k on it.

Ford 6.0L Power Stroke Diesel :: Tranny Temp Same As Coolant?

This is the only 6.0 I have owned. My tranny temp (with the Torque Pro) is pretty much always the same as my ECT. My ECT will move, and less than 2 seconds later, the tranny will move to the same temp. Is this normal? I was expecting lower tranny temps, but maybe it should be the same because of sharing the radiator.

Ford 6.7L Power Stroke Diesel :: 2012 - Tranny Slipping When Towing 5ER?

Took my first camping with 2012 King Ranch F350 and 37 feet Challenger 12k fifth wheel trailer over the weekend.

I noticed there is lot of transmission slips in first gear. Once it enters 2nd gear, no more slips.

My previous Chev 2008 2500HD diesel didn't slip much with same trailer.

Is this normal for this F350? My rear ratio is 3.55. No slips without hauling.

Maybe I need to ask dealer to check 1st gear towing?

Ford 6.7L Power Stroke Diesel :: 2011 F250 - Tranny Heating Up

2011 F-250 6.7
H&S Mini Maxx
Fully Deleted

What is going on with my tranny. I purchased my truck back in August with only 14k miles on it. It was a weekend camper hauler for the previous owner who drove very little. He bought it brand new and had it fully deleted with the mini maxx put in right away. I bought it in that current condition. Since buying it I have used it as a daily driver. Current mileage is 21k.

About 2 weeks ago I did 2 things. First, I decided to update my mini maxx from H&S's website to make it current as I was having a really firm shift from 2-3 gear. This is a know issue with my year truck due to a solenoid issue and I figured a more up to date tune might work. Second thing I did was tow for the first time since getting it. I towed an open bed car hauler with an SUV on it down the highway for about 150 miles. Prob about 7k#s. While on this trip I noticed my tranny temp go up to 235 degrees. When I reached my destination I parked the truck and stayed the night and returned back down the highway unloaded not towing anything and it still went back to 235. Trip was on the highway and is mostly flat with very few hills.

I monitor all gauges religiously and know my trans has never even gotten close to 200 before. My oil and coolant were both running in their normal mid to high 190 range and everything else appeared normal about the truck. I have talked to several diesel performance shops and received multiple ideas about what it might be. All seem to be in agreement that it is not my tuner as no one else that I can find has had this issue with their mini maxx after updating.

What is wrong range from the solenoid issue making the gears slip causing additional heat.... to my thermostat in the coolant valve having gone bad. I have had it in the local Ford dealership all week and they are completely clueless. They claim that everything they can check with their computer for flow and whatnot is functioning perfectly fine. They also claim that at 235 it is not out of spec according to Ford and that Ford doesn't consider this temperature to even be an issue or something that needs to be fixed.

Ford 6.7L Power Stroke Diesel :: Oil Temp 224 And Tranny 199 At 9k Miles Only - Normal?

I have a 12 cc 4x4 drw. I hauled a bull and a cow about 100 miles this morning. I was pullling approx 6k including the trailer. The temp was about 75*. 50-60 miles into the trip I switched to the oil temp screen and the oil temp was 224* and the trannie was 199*. I was going into the wind which was about 20 mph, and I was traveling 75mph. The truck never lugged down heck it never shifted out of 6th gear. When I unloaded the cattle the temp came back down around 190*. Headed home and the temp got up to 226* and the tranni went to 205*. This was going with the wind and just the trailer. I am using oem 10w-30 motorcraft and motorcraft filters. The truck just has 9k miles on it. I am thinking that the oil temp is a little warm, should I be worried. What should I look for to diagnose. I like to do my own diagnosing if I can, the dealers around me can't find anything wrong even if you point the leak out to them. Should I be using a different oil?

Ford 6.0L Power Stroke Diesel :: 2006 - In Tow Mode Tranny Clunk And Shudder?

2006 long bed with LS diff sometimes gets a fairly robust CLUNK! sound and feel when decelerating with tow mode engaged. It only happens once per 20 trips and only about a mile down the road, and it only happens once in a blue moon. It definitely is the rear end making the noise and brief shudder. Otherwise the truck runs extremely well.

I had the pumpkin off and fluid changed with Ford friction modifier added at about 100,000 miles. Truck is at 160,000 now. I just got done with a trip in the mountains of Idaho carrying a truck camper and used tow/haul mode extensively for engine braking and climbing, worked like a champ. This was just one trip of many this summer. This is about the only thing wrong that happens on my truck, but usually occurs before I get very far from the house. Should I just forget about it?

Ford 6.7L Power Stroke Diesel :: How Long Tranny Temp Takes To Get Up To Normal Range

I know that average normal tranny temps for the new 6.7s are 200 degrees give or take which my truck does as well. but I'm wondering about how long is normal for the tranny temp to get up to that normal range? My truck can take anywhere from 20 minutes to almost an hour depending on if I'm on highway vs lower speed driving and it's been that way since I bought it. Am I worrying over nothing or my worries not just worries?

Ford 6.0L Power Stroke Diesel :: Oil Leak Coming From Seam Between The Tranny And Engine Case

I started having an oil leak under my truck in the last week or so and when I went under the rig briefly (it is raining here) it looks like it may be either coming from the oil pan itself or the seam between the tranny and engine case.

I thought I'd try the easy solution by torquing the appropriate bolts. Looking for the torque specs for these two sets of bolts or have any other suggestion where the oil could be coming from?

I have ~130K on the truck.

Ford 6.0L Power Stroke Diesel :: No Throttle Response In Gears After Injector Install

I just completed installing rebuilt injectors in #2 and #4. for the 2nd time. The first set had failures with those two. After assembly, the engine runs rough which is understandable considering the air introduced. I can run the RPMs up while in neutral or park, however; there is almost no throttle response in drive or reverse. It will barely move and only slightly raises the RPMs. I am unable to drive it to get the air out until this particular issue is solved.

Prior to the tear down for #2 and #4, the throttle response was fine.

Current Codes:
P0272 - I am hoping this would go away once the air is gone.

Software:
AE w/ Ford Bundle (New to me)
Buzz test is fine
Power balance looks great
FICM logic and power are good

Skills:
DIY w/ limited electrical knowledge

Recent Mods in last 300 miles:

Ford 6.0L Power Stroke Diesel :: 2006 - Failed Glow Plugs And Engine Flutter In Upper Gears

I've recently gone through and replaced all 8 of my '06 6.0's glow plugs as the check engine light has successively come on (I first did #3 about a year ago, then #5 seven months ago, #1 and #7 two months ago, and #2, #4, #6, #8 about two weeks, did all 4 on the drive side even the code was only for #6). A light came up for #1 again today, so I'm wondering would this be symptoms of failed glow plug control module? Also, can a failed module cause the glow plugs to fail prematurely? Haven't had a chance to ohm the plug yet.

The truck has also has been hard to start when cold and had a pretty bad engine flutter the past 8 months when cold at medium range rpms in the upper gears (1500-2000 rpms in 3rd, 4th, and 5th gear and accelerating like a grandma). I don't know if it could be glow plug related, or a bigger issue (I did the EGR/Oil cooler myself about a year ago as well and things ran good until the winter hit). If I plugged the truck in over night over the winter, the flutter was not nearly as bad, but now it's summer and it's still not liking the cold take offs.

Ford F-150 - 1997-2003 :: CEL Code P0707 - Tranny Started To Slip / OD Light Flashing

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.

Accent LC (2000-05) :: Tranny Slip From 3rd To 4th Gear Around 45 Mph When Get On Gas Too Hard

I recently bought a 2002 Accent with the 1.6 auto 133000 miles. I have been reading the postS around here about the crappy transmission. My car seems to have some life in the tranny still but it has slipped from 3rd to 4th gear around 45 mph when i get on the gas too hard. Its also a little sluggish to start off. My question is should i change the fluid out knowing i have a slipping issue? The reason i ask is that last time i changed the fluid and filter on a Jeep that was slipping i ended up having to rebuid it. Is that a real possibility if i change the fluid in this Hyundai?

Suzuki - Forenza :: While Driving Tranny Will Seem To Slip Into Neutral And Rev

I have a Suzuki forenza - whoops! Anyway it is a 2007 automatic with about 25K miles. It started doing the following: while driving it will seem to slip into neutral and rev. For example, driving on the freeway at 65 mph; foot slightly on the gas it seemed to literally jump out of gear and the rpm shot up for a few seconds and then jumped back into gear. It also some times seems to clunk into reverse when backing up and occasionally seems to be in a lower gear than necessary when driving - revving while staying in gear - literally like it is in a lower gear than necessary. It has a 7 year/100,000 mile power train warranty. I took it to the dealer and they said they needed to replicate these things themselves before they could do anything about it. They would not just take my word. The service manager also said that it could be the computer system as opposed to the transmission itself.

Lexus GX 2004-09 :: Sunroof Rattle / Tranny Slip Under Certain Conditions

Took vehicle in for two things last week and they said both were normal for the vehicle.

1. Sunroof rattles. I can physically push up on the sunroof and feel a little play in it. It doesn't leak or anything, but does rattle on certain roads. Dealer say it's tightened to standards and within normal expected specs for the age of the vehicle (2007), but after feeling the sunroof in my other car that has no play in it whatsoever, I'm a little skeptical.

2. Under certain conditions, the tranny seems to slip/pause and then grab a gear. It happens on off-ramps usually. I let off the gas to slow down and the give it gas to carry me through the off-ramp. It feels like a clunk or the tranny slipping trying to find a gear and then it finds one and noticably clunks in. Dealer hooked up a computer to it and it says it's operating noramlly and the clunk is just a product of the way I drive and the electronic shifting computer. I've had my drive shaft replaced thinking this was the problem, but it's still there.

Ford 7.3L Power Stroke (1999-2003) :: Tranny Slowly Go In Drive

Tranny rebuilt, truck in sig, and beefed up 2 1/2 years and 30K miles ago. Recently started going into D after 10 to 20 seconds after putting it in gear, cold or hot. Very frustrating, especially when trying to maneuver a trailer.

Transmission builder has been running his shop for 20+ years, all makes and models, not Ford specific. I choose him because he runs a local business, has a good reputation, and happens to live less then 1/4 mile from me.

I have searched the forums, and read where Mark says this is loose valve body bolts, or forward drum going out. Builder can't grasp where it would be drum seal if it doesn't do it all the time, which it doesn't. He said it sounds more like something electrical, but there are no codes stored on pcm.

Builder also said he would pull tranny to check drum. Does this sound like I'm moving in the right direction? Or can it be something else?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - How To Get Better Tranny Shifts

'00 PSD w/ 291k on the clock. Starts easily, runs good, only complaint is (what I consider to be) the soft shift of the tranny. Years ago, when I bought it, it came with a Super Chips Tuner. I've never max'd it out, just usually run on the performance tow. Is there any way to clean up the shifts and make them a bit quicker with less slip. When it's time to shift, dammit, I want it to "SHIFT", not slide into gear. I don't expect it to hit the gears like a manual valve bodied drag car tranny. But, there should be something to fix this without spending a bunch of $$$..

Ford 7.3L Power Stroke (1999-2003) :: Oil Leak From Rear Lobe At Pan - Tranny Out Next?

So last year I pulled the motor and put a new pan on. Since then the oil has leaked from the rear lobe at the back of the pan. No oil leaks up top of engine. So I pulled the tranny and am going to put in a rear main. I also see a plate that bolts on the back of the motor and the bottom glues to the pan. I am concerned I did not glue the pan well enough in the lobe as only about 1.5 inches of the lobe has a small amount of grey rtv sticking out. How do I remove the aluminum mount on back of motor that the tranny bolts to? What seals the plate? Oring? Gasket?
