Ford 6.0L Power Stroke Diesel :: Torque Shift Trans / 4 - 5 Gear Shift Under Hard Acceleration
I have been having an issue with my 4-5 gear shift under hard acceleration and know that a rebuild is due soon but I was wondering if any high performance kit available with all the clutches and friction discs needed to rebuild.
View 6 RepliesFord 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 6.0L 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 :: Automatic Transmission Sometimes Not Shift Into First Gear
I have a 36 foot motor home on a 2000 Ford F53 chassis. (similar to single axle freight trucks and school busses) After getting one set of the rear wheels partially stuck, which resulted in some spinning of that side, the overdrive off light on the shift lever began to blink and the service engine soon light came on. The fault code said, "speed sensor showing more than one mile per hour". Now the automatic transmission sometimes will not shift into first gear after stopping and has to be manually downshifted, after which, it works fine.

I noticed my '99 started getting difficult to get in gear & shift, within a coupe of days the peddle was barely off the floor before it would engage. A day later it started 'creeping' if started while in gear. Replaced the master/slave cylinders with no change.
Is a clutch replacement the next step? Just thought I would ask before throwing money at it, since the only other times I've had clutch issues there was slipping or it just plain exploded.
Ford 6.0L Power Stroke Diesel :: 2004 - Automatic Transmission Blowing Fluid Out Under Load Only
I have an 04 F350 automatic blowing fluid out under load only. Had it serviced the first time it happened two weeks ago. They found no issues and replaced the fluid and filters. Drove truck about fifty miles, no load, no problems. Took her out this morning in tow/haul mode with load and made it about 20 minutes before I noticed it warming up. Pulled over and it is blowing fluid out the right side of the pan.
View 6 RepliesFord - Focus :: 2001 - Brake Pedal Feels Hard / Transmission Hard To Shift From 1st To 2nd Gear
Could my brake issue be related to my transmission problem? Neither are constant. Brake problem= sometimes the brake pedal feels hard, like there's no power brakes (I drove a car once. ..looong time ago. .. that had no power brakes or steering) but it will kick in after a short distance. Transmission prob= seemingly unrelated, is a problem shifting from 1st to 2nd gear. This has happened maybe a 1/2 dozen times, the first time and mostly when in heavy commute traffic and when going between 1st and 2nd gear because of the slow commute speed, but also at other times when not in lengthy slow commutes. When it doesn't shift, the odometer doesn't work (shows only dashes) and an engine light comes on (the sprocket/gear looking one). Usually the transmission will eventually shift and the light goes off.
I read that the brake problem might be a vacuum hose problem? Something about a booster? Is this dangerous? or is it like having a car w/ no power brakes? Going to have my transmission looked at this week. Read on another site about dropping valve seats on this year car. If there's a major transmission problem, I'm wondering if it's worth fixing? I changed, timing belt, water pump, front and rears brakes, tires. 143,000 miles.
Golf/GTI VII :: Automatic Transmission - Will Not Shift Into 2nd Gear
2200 Miles... It will not shift into 2nd gear in automatic and the rpms race up to 4000 when going about 20 mph. The only way to get it to work again is turning car off and on again. It has only happened twice.

My tranny is slipping all over the place . I recently less than 1500 miles ago changed tranny fulid, tree branch and TP filter, ford filters, and 8 to 9 quarts of mercon SP. My truck is shifting like a bucking bronco. Came up with PO671. So should I replace just the 1 solenoid. Or all the valve body? I plan to run a gauge in cab to see shift pressures for testing purposes to aid in troubleshooting for current issue... reason for fluid change is history unkown.

Ford 6.7L Power Stroke Diesel :: 2011 - Hard Shift From Park To Drive Or Reverse
2011, 69,000 miles. My truck is experiencing very hard shifts from park to drive or park to reverse after a cold soak. It goes away once warmed up. I can't find any excessive driveline play and my transmission fluid level appears fine and in good condition.
The last repair done on my truck was around 7,000 miles ago and it was for a transmission fluid leak around the bell housing. They just replaced the seal between the torque converter and transmission.
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.
Rodeo :: Automatic Transmission - Delay In Shift Points Going From 2nd To 3rd Gear
I started experiencing a delay in my shift points going from 2nd to 3rd gear. Then today I was driving and my automatic transmission wouldn't shift into third gear...the speedometer stuck at 20 mph...and it would rev all the way to red line, but wouldn't shift.
There is no "abnormal" noise coming from the transmission, or from the drive train. I suspect that this has something to do with the shift points and the computer rather than a mechanical problem with the transmission.
I would like to know what it could be before I take it into the dealer to get it diagnosed.
Mercury - Tracer :: 1998 - Automatic Transmission Won't Shift Out Of 2nd Gear
Recently I had a stuttering and squealing from a belt. I was able to shift into all gears with no problems. Before I could get it looked at, the squealing stopped and I was unable to go faster than 30 mph. The belt and pulley were replaced, but the car now will not shift out of 2nd gear. Transmission fluid is good, and has not been leaking. Does this indicate that I will need a new transmission? Or is there possibly a less expensive possibility? I've heard that some vehicles have what's called "limp mode". Also, is it safe to drive at 30-35 mph., and what damage might I do by driving it?
View 4 RepliesFord 7.3L Power Stroke (1999-2003) :: Loud Gear Meshing Like Grinding Noise - Delayed Hard Shift 2 - 3
I have an early 99 F250 4x4 7.3L..... 4R100....
Brief history, a while back on way home from work I let off of the accelerator and had a loud gear meshing like grinding noise, got back on the accelerator and went away, let off and back, so I quickly stopped and pulled over, went through the gears and reverse, everything seemed ok,??? went on my way, got home parked the truck and went about my evening. came out next day to leave and truck wouldn't move in reverse, forward but not reverse. long story short I was told that the snap ring internally probably came out, I have heard of this being a big issue with these, so I set up for it to be rebuilt, got it back and installed and still same issue, what the crap so I ended up having to pull it back out and amongst my own trouble shooting I found the simple issue and was the nylon riders on the 4hi/4low shifter fork were completely gone and allowing the planetary group to free float in and out of 4x4 neutral!!! NOW on to the issue at hand. so far only thing has been done is rebuilt and those fork riders replaced.
now I can move but 2-3 upshift under a load(more noticeable) has a delay going from 2nd to 3rd and under a load it hits hard. I talked to the guy that rebuilt it and he said that the rebuild kits don't always the right springs for the valve body and causes shift issues, so he talked me into the shift corrector kit which I researched and did see what he was saying, so had that done and still no better, still does it, however, it does shift into the gear softer but didn't fix the delay or the hitting hard when it did finally go into 3rd.
After being forced to drive it that way I have since determined that what it happening is it is coming out of 2nd with a second and half pause and then shifting into 3rd, the hard shift comes in to play because during the delay the torque convertor is locking up making it a direct drive like popping the clutch on a standard!!!
I just swapped out the sol pack and I heard from a youtube video that the bolt next to the 2-3 upshift valve on the valve body could be to tight and making a sticky valve, so I re-torqued all the bolts and nuts put all back together and test drive proved to be worse, I now have same issue in all upshifts. all hit hard now, I am at a loss and don't know where to go from here, I can only imaging the sol pack is causing this but I have yet put my org one back in to see... oh and I found two bolts on the accumulator stripped and found one non torqued bolt on the main valve body!!
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.

We are on vacation pulling the 5th wheel. On the last of the three days driving the transmission starting doing something I have never seen. When running about 60mph and starting up a grade, when I push the pedal and it should shift from OD down, it bucks really bad. It only does it under those conditions and only when towing. It does it when the tow/haul is on and tow haul is off. Also, in the afternoons on the last two da,ys the A/C has started to turn off. The fan still runs but the cooling cycles off. After a while it comes back and is ice cold but then cycles off again. It only seems to do this when the engine fan is running to cool off the engine under load. I have it scheduled at the local dealer for a transmission service and A/C check....
View 12 RepliesFord 6.7L Power Stroke Diesel :: 2012 F350 - Trans Would Not Shift Into 6th Gear
My Father In-law has a 2012 f-350 Dually with 4K miles. He tows a 9K lb camper and until our last trip the truck ram flawlessly. On our return from Myrtle Beach to central NC we were on a freeway traveling at 63 MPH and his tranny would not shift into 6th gear. Tow haul was on. There was some headwind (10MPH) but no large grades or any reason we can think of not to allow an up shift. His display did show a countdown to empty of the exhaust fluid 450 miles to empty.
He took the truck in for service and no codes were found. Dealer did not find any TSB's addressing the tranny issues. Is the sixth gear up shift in tow haul set very conservative? Does it hold 5th unless the load is below a certain value? Other trips we have been on have been mountain towing so 6th gear shift would have been on down hill or level sections. Dealer wants us to bring it to them when it won't up shift next time but dealer is not along a freeway.
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.
