Ford Super Duty (1999-2016) :: 4r100 Transmission Shifting Hard

Recently I have had an issue with my auto which was just rebuilt. About 500 kays after i picked it up it shifts dangerously hard and immediately into all gears at around 20-40 mph, converter also locks immediately. The speed sensor in the box was replaced with the rebuild but I'm having it replaced again this thursday just in case.

Just for the record I cooked it on the beach a while back, the speed sensor was replaced with the rebuild as it was doing the above, the od light also flashes when this occurs, before and after the rebuild.

Prior to cooking it never had an issue.

What could be causing it? I'm starting to worry it cant be fixed, have done a google and tried a couple of things mentioned. Code says wiring issue associated with speed sensor in box.

Ford Super Duty (1999-2016) :: 2001 F250 - 4r100 Won't Engage In 4th - Hard Shift Between 1st And 2nd?

I have an 01 f250 with a 4r100. Trans has not been slipping at all and yesterday it started a rough shift between 1st and 2nd. (3-4K Rpms) At the same time 4th gear stopped engaging. Shifts out of 3rd but does not go into 4th. I can hit my od button and it will shift back into 3rd and start pulling. Still no slipping just doesn't want to change 1-2 or engage 4th. I have done a full trans fluid change including new filter and tc. Old fluid looked fine with no metal flakes or garbage in it. So all new fluid still same problem. I was thinking of changing my shift solenoid.

Ford Super Duty (1999-2016) :: Transmission Temperature Sensor Location 4R100

My truck has a bit of an interesting trait. Unless it's just about freezing, my transmission is just about always at operating temperature. If it's 50*F outside and I start the truck, the Trans temp is smack dab in the middle. If it's 30*F outside it starts just a little above cold then is "warmed up" when I drive it down my short street block, which ain't right.

All the rest of the time, it's always reading middle of the bar temperature. My old 5.4L never did this. My 7.3L does. Best I can tell is it's a fault in the temperature sensor for the transmission. I don't have a scan gauge yet to get the readings but will be getting one. Just need to know where the sensor is at so I can have a starting point.

Ford Super Duty (1999-2016) :: F250 - New Larger Tires And Hard Downshift

I put some bfg at's on my '16 f250 6.2 today, 285/70r17 from 245/75r17. Has went to a larger tire and had funny downshifts? I had two hard down shifts on the way home from tire shop that I have never had before. I'm hoping this will go away once the computer relearns. Should I disconnect the battery or anything or just drive it and let it learn? I'm a little disappointed, the tires still look tiny, and checking clearances at liners and radius arms, I could have cleared a lot more tire easily. They sure looked bigger on dads '04. These will do me for a year or so until I can upgrade wheels, tires and suspension.

Ford Super Duty (1999-2016) :: 4r100 Won't Decelerate With O/D Off?

My truck lives with a trailer behind it and I always turn overdrive off when under 50 mph and turn it off to slow the truck and trailer down when coming off the interstate. About a month ago when I turned od off to take a exit truck did not decel. Just shifts to 3rd and engine goes to idle even at highway speeds. Truck still tows fine. No trans codes no flashing od light. Trans was rebuilt at 163,000 miles have 183,000 now. I'm stumped to what it could be.

Ford Super Duty (1999-2016) :: 4R100 Convert From 2wd To 4wd

I have a friend who just burned up his transmission. He needs to get on the road as quickly and cheaply as possible (he uses this truck for work).

We found a local 2wd 4r100 out of a 2000 but it is for a 2wd rig. His pickup is an 2001 F250 7.3. 4x4.

What is involved in setting up the 2wd transmission for the transfer case. We can salvage parts from his old transmission if need be.

Ford Super Duty (1999-2016) :: F250 - Hard To Turn Left

I have a 1999 f250 sd with the 7.3. I'm not sure what is going on with my pickup. When I turn to the right i can turn with one finger, but when I turn left i have to put some muscle into it. Power steering fluid is full. I raised the front end and it turns both ways easy. My ball joints feel fine, there is no tire shake when i have it off the ground. My tie rods feel fine also, nice and tight. I was thinking about replacing the steering sector to see if thats the issue but wanted to get a second opinion first.

Ford Super Duty (1999-2016) :: 2002 F250 - Transmission Shifting Hard

I have a 2002 ford f250 with the 7.3l diesel. I recently installed a ts performance chip. On my pcm. And after i first tried all the different stages I didn't like how my transmission was shifting hard. So I contacted the manufacturer and he told me they could reprogram the chip for smoother shifting. So I removed the pcm and removed the chip. But when I went to reinstall the pcm I bent one of the pins on the pcm some how.

So I took it back out and straightened the pin with pliers . i reinstalled it back in the truck. Only to find when I reattached the battery cable I have no power to anything ignition ,horn, lights,Cigarette lighter etc. So my question is if the pcm is bad, or not contacting properly due to the pin being messed up. would that have anything to do with the lights and horn and all that? I suspect its the gem bsm or Vsm. Whichever one my truck has. But really not sure because everything worked fine just 20 min b4.

Ford Super Duty (1999-2016) :: 5R110 Transmission Would Suddenly Hard Shift

I have a 2005 Ford 6.0L Diesel with the 5R110 transmission.

About a month ago, i started seeing some strange shifting issues with the transmission. While driving normally, it would suddenly hard shift (slam itself into gear), the entire truck would shake it shifted so hard. It would also cause the Tow/Haul indicator to start blinking. (my understanding is that the Tow/Haul light indicates an error code).

I drained/flushed the transmission, installed the larger pan/with the improved filter. I put Mercon LV back into the transmission (what type of fluid was in there before).

The problem still persists, and got a bit worse. The truck is almost un driveable at this point. Still getting Tow/Haul flashing messages. Can the error code be read by an standard ODB2 reader ?

Ford Super Duty (1999-2016) :: 2011 F350 - Transmission Shifting Hard From 3 To 4 Going Up And 2 To 1 Going Down

I have a 2011 F-350 6.2L that has extremely hard shifts from 3 to 4 going up and 2 to 1 going down. Sometimes on downshifts it feels like something has ran into the back of the truck. I had the computer updated when the truck had approximately 40,000 miles on it and he assisted a little bit. The truck now has 140,000 miles and it is back to shifting horribly. I put it in the shop at the dealer on 30 December 2013. The dealer says that the problem is that the shift solenoids need to be replaced but that they are not available. The truck is still sitting at the dealer and I am being told that the parts should be available mid February.
