Ford 6.7L Power Stroke Diesel :: Transmission Clank / Sometimes Downshift Hard

I have an 2011 6.7 that has a h&s tuner. Lately my transmission seems to be confused about what gear it should be in when I'm driving about 45mph. It will sometime downshift hard. I have a early build 2011 and heard that it could be a solenoid problem with the transmission.

Ford 6.0L Power Stroke Diesel :: Transmission Need Extra Power To Downshift

I just purchased an 04 f-250 Lariat. It only has 103k miles. first time diesel owner. When I drive it, it shifts smooth as ever. BUT, when I need that extra power to downshift, nothing happens. Nothing raddles, it stays cool when it warms up. Again, normal driving behavior its fine, until it needs to downshift. I have two referred mechanics, but id like to get a little more info before I take it in.

Ford 6.7L Power Stroke Diesel :: 2011 F350 - Clunk / Clank At Both Wheels Around The Brake Area

I have a 2011 F-350 CCSB 4x4 w/ 20" Wheels and the electronic locker. I have had for some time a noise when I go over small bumps (pulling into garage up a 1" lip) at slow speeds. It sounds/feels like side to side movement. I have traced this down to what sounds like looseness inside the rear differential. To recreate, I lay down and shove hard on the spare tire. This pushes the truck side to side. I can hear a clank/clunk at both wheels around the brake area.

Ford 6.7L Power Stroke Diesel :: Transmission Downshifting Hard Into 5th

I tow a car hauler that is about 8000 lbs. On my last trip occasionally when the truck would downshift into 5th under a load, it would bang in there pretty hard. Not a smooth transition, not every time just some times. Just wondering it that was normal or the start of a potential issue.

Ford 6.0L Power Stroke Diesel :: Transmission Slammed Hard Into First Gear And Sometimes Will Not Upshift

Everything was fine, running PHP 200X tune, switched to PHP 65 tow and took the 5er toy hauler on vacation last month. Pulled a lot of mountains,etc. While camping, took the truck unloaded to get fuel. Engaged tow/haul going down a mountain to utilize engine braking and the tunes "exhaust brake" and the trans slammed HARD into first gear. This happened twice. I refrained from using tow/haul. Heading home 450 miles with the 5er, I utilized tow/haul again (had it on the whole time, just like on the way down) and the truck and trans were flawless. Get home, switch back to 200X, and I'd say within a week or so, began having trans issues. Loaded stock tune, reset KAM with SCT, disconnected batteries with headlight switch on for a couple days, reloaded 200X and drove it for a couple days. No change.

It felt like the trans was slipping, not "going" like it should when on the throttle, and would sometimes not want to upshift. It would just act "weird". This would usually occur under 40 - 70% throttle (I rarely ever get on it more than that), but sometimes less. Never got any check engine light or tow/haul flashing.

So today I finally did what I should have weeks ago, took off work and ran the truck to a shop.

- First the tech hooked it up to the scanner. No codes.

- Test drove it. He said it drove fine for him. It was fine for me as well, driving it from my house to the shop (I didn't "get on" the throttle though).

- He monitored the voltage from the trans temp sensor. He said the voltage was fine, didn't spike or do anything crazy. He didn't seem 100% positive on this but, said it starts out at 5V cold and voltage should drop as the temp increases, which it did. However, the temp started out at 300 and then dropped to 200 as he was driving. #1 the temp isn't (shouldn't be) that high, and #2 it should increase while driving not drop. The temp shown on my Torque Pro app hit 149 on the way to the shop and 168 on the way home (90 degrees outside). So he seemed to think there was something screwy there.

- While driving it, his scanner showed a trans overheat (over temp/high temp, whatever) code, but no check engine light or tow/haul flash.

- Drove it home. Trans was fine until I got on it a bit and then it acted funny again. But just driving normal with light throttle it is fine.

* Thinking about trying a new temp sensor.

* Could it be in limp mode which is why it feels like it is slipping, i.e. doesn't have the normal power I'm used to?

* When the tow/haul light flashes, is it the tow/haul light on the instrument cluster? That's the only thing that lights up when I'm in T/H. Where you push the button never lights up. Assumed it was just white lettering and not a light.

Ford 6.7L Power Stroke Diesel :: Automatic Transmission Hard Shift Second Gear

Well I've been towing for almost 150,000 miles with a 2012 6.7 Lariat 4 wheel drive. Things have been going pretty well with the truck. I noticed some sluggish and indecisive type shifts early on but now I'm worried. I depend on this truck for pulling a horse trailer all over the country and Canada. Just recently I've been getting a hard shift or a thump or a clunk when shifting up or down in to second gear. I'm at about 152,000 miles and did a hot flush with LV ATF at about 148,000 miles. Should I worry or keep running?

I have a 97' PSD I'm thinking of giving a nice paint job and a flat bed but am reluctant to do so due to financial concerns and the fact that some folks may not want to see me pull up in an old truck no matter how nice it looks. My tranny temps have been stating under 200F and I really keep an eye on the temps when running up and down the hills while towing. The trailer is a 35' Gooseneck with a max GVRW or 14,000 pounds. Should I wait for the tranny to grenade and then drop in a built tranny and if so who's building these tranny's stronger than stock? Long time no see but this site has always been my go to for all my Ford truck questions, upgrades, etc.

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Transmission Shifts Hard To A Lower Gear

I currently have a 2006 F-250 6.0 with 187,XXX.

My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.

Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.

The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.

The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.

I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

Ford 6.7L Power Stroke Diesel :: 6r140 - Transmission Slams Hard Into Reverse / Shifting From 1 To 3 Is Awful

I'm having problems with my 6r140 in my 2011, the truck is an early build around 8/2010 I believe.

After cold soak when shifting into reverse after allowing engine to warm a bit the transmission almost always slams hard into reverse.

After that shifting from 1-3 is awful, the transmission will try to go into 3rd but downshift to 1st then fail to go back into 3rd multiple times. This situation is extremely dangerous when trying to pull into traffic.

Oh and once the transmission gets into 3rd it will skip 4th and go right into 5th. There is only 94k miles on this transmission/truck.

I just bought this truck about a month ago, does this sound like an issue with the solenoids in the valve body?

I'm very mechanically inclined and can swap them if need be but now we're talking few hundred in solenoids and then getting the trucks pcm flashed right?

Also fluid has been changed and I used mercon lv.

Ford 6.0L Power Stroke Diesel :: Transmission Engages Hard On Reverse / Vibration And Some Knocking Sounds On Takeoff

05 F-350 6L .. Automatic Transmission

When I got the truck I noticed it would slam hard into reverse. Ever since it is taking longer to engage reverse gear and now I have to rev it to 1000 rpms for it to engage with a hard SLAM.

I also noticed that if I do a fast take off, there is a knocking sound coming from drive shaft/differential area (like knock knock knock knock knock then goes away). Then a slight vibration ending at around 30 kph (~20 MPH). There is also some oil leaking from the transmission. I added some mercon sp yesterday - it was a bit low.

My guess for the knocking and vibration is the center support bearings and U-joints. Transmission??? One thing I know I am going to be banging away at that shaft but the transmission problem really scares me.

Ford 6.0L Power Stroke Diesel :: Intermittent Crank Now / Key Will Just Click The Solenoid

I just reinstalled the engine and got her running. I installed a new 6.4 starter (reman) and she spins perfect. I was experiencing this same issue prior to startup and thought it was weak batteries. The key will just click the solenoid and it turn the engine over.

Quick synopsis of what I've checked:

All grounds
All cables tight
Batteries are fully charged
Power at right fender pigtail leading to solenoid when key is engaged (tomorrow I'll ck voltage at work today)
Checked starter connections
Checked continuity on the 10g wire from the fender to the starter...all good even wiggled it hoping it might have broken internally...

To me it sounds like a bad connection but I did not mess with the harness (firewall) aside from bungeeing out of the way vertically. I can hook up a charger and she will crank with the key. I can disconnect the fender 10g and crank it from the battery with no issues.

I've quadruple checked for loose connections. Didn't have this issue before so not sure what happened. Relay sticking maybe?

Ford 6.0L Power Stroke Diesel :: 2004 Excursion - Clicking When Attempting To Start - Solenoid?

04 excursion 6.0 auto. New batteries a month ago. New alternator (New Bosch) 6 months ago. Charging system shows 12-13 volts on scan gauge with engine off, 14 with engine running. Drops to 10 or 11 while actually engaging starter.

Every once in a while, often when the engine is hot (in fact I can't ever remember this happening when it's cold) the solenoid clicks like it would when the battery is dead. So far, it does this while it's actually engaging the starter, so I hear the solenoid clicking under the hood while I hear the whir of the starter under the floor board.

Never had this happen before. Not sure what part is trying to tell me it's on its way out? Heat soaked starters are harder to start, or less powerful, or something, right?

Ford Super Duty (1999-2016) :: 2015 F350 Diesel - Hard 6 To 5 Downshift

2015 F-350 diesel purchased Sept 2104. When towing my 16,000 lb 5th wheel the 6 to 5 downshift seems to have gotten much harsher in the last few months. About 10,000 miles on the truck, much of it towing. Is this an indication of a developing problem?

Ford 6.7L Power Stroke Diesel :: When Engage Low Range In The Diesel / Transmission Starts In 2nd Gear

Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.

One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).

I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.

These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.

One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.

Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.

Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.

When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.

Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.

Ford 6.7L Power Stroke Diesel :: 2012 F250 Diesel - Transmission Noise When Shifts Into 5th Gear?

When the truck shifts into 5th gear i instantly feel a constant vibration and noise until it shifts to 6th gear. This happens nearly every time while driving at 40mph. Rpm range 1200 - 2000. I bought the truck new on June 30th and noticed the problem on my way to work on Monday July 2nd. Took it to the dealer on July 5th and the tech said it was the torque converter slipping. I drove it home because they didn't have time to work on it. Took it back on July 12th and the dealer has had it since (currently 30 days) They originally told me it was not the engine or transmission and it was an exhaust problem. Last week they said it was the motor mounts and said they would be done.
