I have a 99 7.3 F350 with 5 speed manual with over 300,000 miles. Grinds bad shifting into 3rd, and nothing happens in 4th. I think it is a S5-47-ZF. Is a 6 speed manual comparable to bolt up to bell housing?
View 2 RepliesI've got a 2000 F-250 SuperDuty with the 5.4L V8, and a standard transmission and about 140k miles - just bought the truck several months ago. Trying to figure out what's wrong with either the transmission or the clutch. Here's the symptoms, any feedback is welcome:
1. If I shift too quickly into 5th from 4th, say 'pushing' from 4th to 5th directly, it grinds and chunks in every time.
2. If I shift slowly, 1-2-3, 4th into neutral, neutral and push right to line up with 5th, then into 5th, slight pause on each move, then it usually shifts into 5th silently and no problems ...but sometimes will grind just a tad.
3. If I shift from 4th into Neutral, leave it in neutral and let the clutch out then step on the clutch all the way and wait before shifting into 5th ...even if I wait several seconds (say 'close to 10 seconds'), it will grind every time ...a good grind that bugs me to do. I'm careful to avoid this.
4. Usually, if it grinds into 5th, I can shift down to 4th, let the clutch out and drive a short way and try again ...and it'll grind again. Best way to avoid grinding into 5th is to drive normally, and use the 1-2-3 'slight pause' method of shifting into 5th. This is what I do all the time, trying to make the tranny last as long as possible.
It's like the 5th gear synchro isn't working well, or perhaps the clutch is not fully disengaging? What's wrong? I wonder if the truck (haven't looked it up yet) has a hydraulic clutch and maybe the clutch is not fully disengaging ...pumping the clutch pedal sometimes seems to work, but most often doesn't. Sometimes, I have difficulty shifting back down into lower gears as well ... no grinding, but you have to double clutch just right to get it to go into gear (3rd, or 2nd).
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.
View 11 RepliesThe tranny is shifting really hard between 2 and 3 if I feather the throttle it can be a little less of a jolt but still enough none the less iv never done a filter and fluid change as I just got it it has 235000 miles 99 v10 super duty 4x4....
View 8 RepliesI bought my 2011 F250 FX4 about 2 months ago. A little about the truck: 6.2 liter gas. XL FX4. Manual 4x4. 6 speed auto. Supercab. Long bed. 42,000 miles. (1,000 of them mine.)
Until yesterday, the truck has performed absolutely flawlessly under all conditions. Then, randomly, I had what felt like a "missed shift" as I was leaving my dog's veteranarian yesterday. I pulled out onto the highway and as the truck attempted to shift into second gear, it didn't "catch" second. The gas just revved up and I had to take my foot off the gas pedal and put it back down to get second gear to engage. Most of my driving is stop and go around town and this has only happened once in probably well over a thousand stop and go situations. Should I be worried or was it just a fluke?
Also, FWIW, I did plenty of stop and go driving today without a single problem.
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?
View 1 RepliesNew truck 11000kms ago thats done medium amount of work but nothing heavy or sustained for long periods of time. I get the feeling of clutches slipping especially when truck is cold but also when normal temps. Doesnt make any weird noises or anything. I can really notice the difference in torque if in manual mode being much better, but still not perfect if i stomp on the gas pedal and go through the gears in manual mode will still slip. Also is really harsh shift if i come to a halt in 3rd manual mode with the brake pedal depressed push minus button the truck makes very loud clunk noise into gear 2 then 1. Took it to ford they couldnt find anything ? Thinking of trying another dealer.
View 2 RepliesSo I was driving earlier this morning and I noticed my overdrive light blinking, I didn't think much of it since I know the multi-function switch is bad and I haven't had time to change it yet, but a while later I was accelerating and just before it would shift from 2nd to 3rd it went to neutral. I played with the shifter a bit and found that if I shifted the column to 2nd I could drive in second, not a problem being only 3-4 miles from home.
I did a bit of digging and found I had blown the OBD2 fuse and saw a few people mention fuses as a possible shifting problem, Replaced that and still having issues. I have found that if i start out in drive I can shift into 2nd on the column then at the proper rpm put it back up into drive for 3rd and 4th. I just had the transmission re-built 400 miles ago and it is under warranty but I want to make sure it's not a computer or some other sensor before I call and bitch to them. I saw a couple posts referring to the shift solenoid but the problem was different.
On dads 04 f350 the 4wd first wasn't shifting to 4lo. Would do 4hi and 2wd fine. Then motor on t-case went bad. Replaced motor 2wd and 4hi still good still no 4lo. Then just 2wd so we unplugged t-case motor and power probed motor got it to do 2wd, 4hi, and 4lo. So we thinking bad dash switch but power probed it and its working fine. So we r thinking VP4C3F-14B128-A/ chassis computer bad just behind/above glovebox. R there any test we can do to confirm its bad? We called local junk yards to see bout getting one, nobody had one. If this is indeed bad where is cheapest get one? What all years use this certain chassis computer??
View 5 RepliesThe other day I was driving to work and I noticed my truck wasn't accelerating right and the transmission wasn't shifting into high gear. Its almost like the truck went into neutral around 2000 rpm. What the issue could be? I really don't want to replace my transmission if I don't have to.
View 3 RepliesBought 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.
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.
View 2 RepliesRecently 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 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?
View 9 RepliesI 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.
View 4 RepliesI have a 2011 super duty with the 6.2 flex. When shifting into reverse, it hesitates, then slams into reverse. Same on the lower gears when driving. This doesn't occur all the time, but the majority. Been talking to a couple other super duty owners (diesel owners) who have been having the same prob, but not as severe. We all have noticed the prob after having charcoal filter replaced. Is this a tranny issue or computer issue?
View 3 RepliesI have a 2000, F250, 7.3, automatic with 220,500 miles. When I purchased my truck used in 2008 (173,000 miles), i had the transmission rebulit by a ford dealership. Okay my problem is now that the weather is cooler here in Texas, when I back out of my parking spot in the morning, it takes several seconds for my truck to engage into drive. The rest of the day it works fine, only first thing in the morning. No problems driving (shifting) during the day.
View 3 RepliesI 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.
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 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.
View 10 RepliesI 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?
