Ford Super Duty (1999-2016) :: 4r100 Transmission Shifting Hard
Mar 7, 2017
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.

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.

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.

Bought truck drove it 240 miles on interstate 80 mph no problems---2001 F350 4x4 auto. Next morning backed out drive and trans fluid trail 6 inches wide. Didn't leak in forward gears (at that time) added fluid and drive to town shifted fine.
Next day gonna drive 150 miles to check out leak. (Son was driving it) said it wouldn't go over 40 mph. Revving high. Hauled truck here on trailer and pulled tranny. Rear housing cracked just before 4x4 adapter. (This trans was rebuilt 10k miles ago) ..
Got used 4R100 from friend who replaced only because he built one for his truck. It was shifting fine etc when pulled 6 months ago. Used cracked trans TC and installed. Test drive no 4th or OD. Pulled trans put TC that came with trans in. Still no OD. Put on scanner while driving. Trans is being commanded to shift to OD but not up shifting. 45mph at 2400rpm.
Pulled plug to solenoid pack inside trans ( this should make trans default to OD / limp mode) still no OD and won't go over 45.
Pulled OD button checked wires inside steering column. All looks great. Not even a heavy rub mark.
Should I replace the coil pack in trans? Where do I go from here? Again this trans was known to be good when pulled 6 months ago.

My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?

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.

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.

I have a 1999 ford f250 5.4 2 wheel drive i believe its a 4r100 transmission. auto. I have reverse but no forward gears. Ive heard this is a common problem , and on my reverse it has to hit 3000 rpm before it even tries to move and D 1 2 i have nothing only thing i hear is the engine sound changes gets deeper. Do i need a whole new transmission or is this fixable.

I recently bought a van that has a hard shift problem. It is a 1995 E350 with a diesel. If I take off from a stop without babying the throttle, the shift from first to second is very hard. Second to third is hard but not as violent. What might be happening?

I have a 1997 f-250 heavy duty with the 7.3 I have been having problems with very aggressive and hard shifting. While it is acting up the overdrive light on the shifter blinks. This problem goes away and it might be good for a month or so, But it always comes back. I have had it to a professional trans tech, He replaced a part on the side of the tranny. I thought it was fixed, But now it is acting up again.

I have been having hard shifting from 1st-2nd when cold. Rpms up to 2000 and let off then goes into 2nd. After that, she shifts fine and shifts well until next morning when she sits overnight. Build tag is August 09, 2001, so no old mechanical diode? Took a sample of fluid and it is dark red (pic attached) and smells like hydraulic fluid...I don't think it smells burned. Does it sound like the calve body 1-2 shift or solenoid pack or needing rebuild?

So I have a 1995 f-250 4x4 with the 460 and a E4od. So when I bought the truck I drive it two hours home and when I got into town it started shifting really hard and searching for gears. So I flushed it and installed a new oil filter because the oil in it was brown. Very brown. And smelled awful. So it shifts good, but what's happening now is that it shifts good in drive when it wants to.
In the morning it works great but when I get in it to leave after school it shifts really late (around 2900 rpm) and hard. So I put it in first and then into second but when it's time for third and I put it in drive it shifts back to first. But if I stop shut it off for a few minutes and turn it back on it works fine. It only does this after it's been sitting in the school parking lot all day. I replaced the mlps but not the connector due to I didn't have time at the moment. Could it be the tps? Something mechanical?

I have a 2012 F-250 ccsb lariat and the shift from 3 to 4 seems to be a bit prolonged as if the converter is slipping and wont go ahead and push it into 4 gear. Also it will want to downshift from 3 to 1 and feels like the car behind nailed you. I have read that the early 2011 had some of this problem and the dealer reflashed the tcm and it did not do much good but as mine being a 2012 mine should have been flashed with the lastest tcm flash from the get go?? Egr fell off and am running Kory Willis tunes through ez lynk so the stealership is probably out of the question. I have also read that changing a couple solenoids( dont remember which ones) will fix the problem.

Well shoot, not even 120k on the odo and I've had my first major problem with the truck, and the one thing I hoped wouldn't be an issue, especially since I don't work my truck hard and 95% is driving unloaded highway as a daily driver.
Last time I drove it coming home from grocery store there was a big racket from down under (transmission area). It instantly didnt feel right - there was a slight drag even when the clutch was in, but rolled fine when I pulled it out of gear entirely. Was VERY difficult to go into first gear. Other gears shifted ok but some of them felt hard too. Would not go into reverse at all!. Slight bit of clinking noises every time I started from a stop, but made it home ok and things seemed to ease up as I went. Today, seems to be shifting fine, reverse works and everything.
Now for several years I've had a noise that I couldn't figure out. I am guessing it's related because it sounded like was coming from tranny area. Often, when starting out from a stop, there was a bit of clinking noise like a couple tin pie pans rattling together just as the clutch started to go. I kept thinking it was loose heat shield or something clanking just under the initial vibration of getting going. Never did find anything loose. I'm guessing it's internal.
I've called a couple local shops and so far no one wants to mess with it. Dam this sucks i hoped the MT would be more reliable, not the first thing to go. I myself have never messed with any aspect of a transmission, though I not opposed to learn however I was hoping to take this on an out of state trip end of May, and I'm not going to have much any free time between now and then.

Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....

I have a 2000 F-550 w/7.3 and a 6 speed ZF transmission. My problem is that when you go to shift into any gear inc. reverse the transmission stays in 5th gear. I pulled the shifter and tried to do it from top of transmission it still stays in 5th. Any thoughts that I could possibly check?

I have a 2006 f-250 super duty with a 6.0 and auto trans. I was pulling a trailer with about 5k of vehicle on the trailer.
Problem : after a long trip on good roads, I had to pull a steep hill. climbing the hill i did not shift into tow mode and all of a sudden my engine raced up to about 3k rpms and seemed to either shift to low or ( maybe ?) the Governor may engaged ?
Anyway I made it to the top of the grade and it seemed to be fine from there.
Question Is the trans broken, or did the computer maybe try to protect the trans ? It seems to work fine still?

I have a 97 F350 5.8 with E40D trans. I bought the truck with it shifting hard thinking maybe a simple filter/fluid change would fix it. It may have worked a little but did not fix the issue. There were 3 or 4 codes that I have already cleared up with new parts. I am still getting a 327 (something with EGR?) and 629 (Converter clutch control circuit failure). These show up in KOEO and KOER self test. The O/D does not flash ( bulb does work).
Parts that have been replaced: VSS, MLPS, new connector going into solenoid pack (tabs were broken), TPS. Removed the trans wiring harness and there is no damage or loose connections. When I replaced the solenoid connector I noticed there was some trans fluid in the connection. I cleaned it the best I could and reinstalled with dielectric grease.
The truck runs fine and shifts in and out of every gear fine its just shifting hard. If I unhooked the battery it will shift perfect for 5-10 minutes but then the hard shifting returns.
The only other thing I can find with my research is maybe the solenoid pack needs replaced. I figured if I take it somewhere they are going to want to rebuild/replace transmission. It seems like it can't be something very major since it will shift fine when reset...

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.
