Ford Super Duty (1999-2016) :: 2002 F250 - Transmission Shifting Hard
Nov 13, 2015
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 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?

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.

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 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.

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?

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 a 2011 F250 with the 6.2 34000 miles and my Transmission shifts hard between 2-3 and 4-5 took it to the Ford dealer and they said it is the shift solenoids are bad but it is cause from the Powertrain Control Module and its not covered by the warranty because it is part of the emission system.

I have a 1994 F-250 XLT heavy duty model. No warning lights are on. A few times a month my transmission will start shifting hard, kicking into the next gear. The odd thing is, if I reset the computer it stops. Shifts smooth as butter. The fluid is a vibrant red and the fluid looks great like it's new. What is going on? I'm getting tired of having this happen. The truck has 108,500 miles on it.

I recently purchased an 02 F250 v10 4x4 with 150k from a local auto auction. The transmission, for lack of a better term, will "grunt" when going into third and in and out of overdrive. It doesn't seem to slip at all and the fluid looks slightly discolored, but it does not smell burnt. No Torque Converter whine either. A friend of mine who has owned 10+ SDs for his business said I may need to replace the TCM. Not too sure about that, because other than the strange noise, the truck seems to shift normally.

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 just got 03 f250 with 6.0 and when shifting has a weird surge/lag thing happening. Reminds me a little of the old 7.3 surge when it was just started on a cold day. Seems to be worse in higher gears.

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.

2002 f350 7.3 ... problems started all of a sudden one day. I have an edge evolution tuner in my stroke. I have it set to make all of my shifts firm. One day it started shifting really sluggish between 1st and 2nd gears only. It don't do it all the time, but it does it more often then it doesn't. I have also noticed when i come to a complete stop and then start out again it seems that it doesn't downshift all the way back to first and when i hit the gas it seems to kinda be stuck between gears and it barely moves until i get the rpms up before it will ease its way into 2nd and the converter locks up.
It shifts a through all the other gears just fine nice and firm like it should, its just the shift between 1st and 2nd. Im wondering if maybe it might be the speed sensors or maybe the tranny filter is getting clogged up? The fluid in it is still nice and red and up to the level it should be. I just bought the truck in october and the fluid was nice and red when i bought it, but who knows if they changed the filter. I have had NO tranny problems with it up until a few days ago when this little problem started.

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 question for everyone out there with any insight of the harsh shifting with these trucks. I have a 2003 f250 super duty with the 5.4l and 126,000 miles on it. The problem I'm having is some weird shifting that has been going on over the last six months and I feel like I am just throwing money at this problem. My truck shifts hard from 2nd to 3rd and from 3rd to 4th with the most violent shifts being from 3rd to 4th! Between shifts is where it Is sluggish I mean if I am not on the throttle from those shift points I switch from driving a truck to a geo metro it is night and day with the felling of loss of power!
I have had it scanned at my local ford dealership and had a full diagnostics done and all I got was "it's since truck and a nice bill to come with it" they couldn't find a thing. So far I have all new motorcraft plugs, cops, changed fuel filter, had my catalytic converter checked if it was clogged,run on two different power balance tests! Still nothing! So now I'm lost I have heard things about these trannys and the lock up but I was told this only had to do with overdrive and it wouldn't happen at other gear changes. I still drive it everyday I have just figured out ways to calm it down if I stay off the gas when it's about to shift for a couple seconds then get back on the gas it is like it never happened.

2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
