The 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 RepliesLast week I hauled my camper (2000 Thor Citation @ about 10,000 lbs) to Moosehead Lake. On the trip to and from I experienced a few problems. Tow/haul was engaged all three times. Trucks got just over 90,000 mi.
1) When shifting, the truck would occasionally stutter, like a gas engine when it misfires. Seemed like it would usually happen when transitioning from a slight down hill to an up hill.
2) Once, after a long up hill pull, as it crested the top, the truck slammed into the next gear, hard.
3)Once, going down hill, the trans wouldn't shift into O.D. until I took the rpm's up to 3000 then let off the throttle. No, I did not touch the brake prior to this.
Figure the tranny's gonna need a rebuild soon. What kind of upgraded parts does the wise and all knowing FTE wizards think I should be looking at? I tow the camper a lot during the summer so I want a trans that will hold up to the abuse. I'm probably stuck with this thing for a few more years.
Ok so some one locked my hubs and put the truck in 4x4 4low i assume my aunt was driving it, truck wouldn't shift from 2 to 3rd is this normal since its in 4low. The shifter also seems pretty stiff and 4wheel isn't used much if there a way to know if 3rd gear toon a crap? Trans fluid seems fine not dirty or burnt...
View 1 RepliesI got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?
View 11 RepliesSo I have a 2016 6.7L love it but it has this vibration at 65 mph that is worse when accelerating up a hill. It feels like an out of balance wheel but I have had them balanced 3 times. road forced 2 times. My dealer replaced the driveline also. I did a test with 400 lbs of concrete bags in the bed and it was vibration free. It almost is like the pinion angle is off.
View 11 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.
So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?
Truck is a stock 2001 f250 7.3 with 205,000 miles. When accelerating or braking from about 40-60mph it starts to shake a little bit. When braking it shakes a lot more from 60 down to 40. But the faster you speed up the less it shakes when taking off. Looked at everything underneath is tight, and it has stock a stock steering stabilizer. Would a new stabilizer fix this you think?
View 7 RepliesI have an issue with my 6.0 that no one can figure out. It has been happening for about 3 years. After accelerating hard, motor will rev out like it just popped out of gear. It is still in drive and the edge cts says 4th gear usually. I have to let off the pedal and coast a bit and everything "sync's" up again and works fine. It can happen from a hard launch from a light or get on the freeway. I recently put an ATS transmission in because I figured solenoids were beginning to fail. Still does it. I am running innovative tunes with sct tuner. It had a Suncoast billet flex plate and ATS 5 star converter. I run Amsoil fluid, it is clean, red, and at the proper level. Truck has almost 80k miles. Also 37" tires and 4.88 gears. It has not done it while towing our 35' toyhauler, but I am easy on the pedal when I tow. I recently checked the transfer case and changed fluid to Amsoil. The old fluid looked good.
View 7 RepliesSo lately I have noticed that my 99 F-250 has a bit of a "bump" while accelerating. Think of it as accelerating with a trailer and something is loose on the hitch, making a sort of bump or thump. I talked to the guy at the parts store and he said to put it in neutral and wiggle the driveshaft up and down, side to side.
When I did that it moved up and down, but not side to side, but I'm not sure if that's because it's just positioned that way or what. The wobble was coming from the slip yoke back by the rear diff. Is this something I should be concerned about? Also, I have an ext. cab and short box, 1 piece driveshaft.
Here's a video (a very crappy video at that), not sure if it gets enough info through or not but hopefully you kinda get how much play is in there.
The truck is a 2012 f250 6.2 flex fuel from alberta canada. This isn't the first tranny form out there that I've heard do this. Tranny seems fine shifts all right just a whine while accelerating.
View 7 RepliesF250 5.4L have had a new fuel pump installed and new spark plugs (one blew out). When accelerating, or at a stop i get a kinda hesitation. It did it when I first bought the truck but put correct size tires on it and it went away. What it may be? I don't have a check engine light or anything and at cruise speed no problem--it's just when a slight load is put on the engine?
View 1 RepliesI have a 1999 F 250. When I accelerate my AC from the vents changes to the defrost. Other than that it works great and is ice cold. Why it's doing this.
View 5 RepliesI 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 RepliesOn 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 RepliesMy V10 was knocking when accelerating under 2000 rpm; rain and moisture made the problem worse. I discovered that the 2-part wiper cowl under the windshield allowed water to leak into the engine compartment and onto the throttle body, which then dripped onto the left side of the engine. This caused the spark plugs to rust and the 3 back ignition coils (coil on plug) on the driver's side to crack and fail. This caused a horrible misfire/knock that was worst under 2000 rpm especially in high gear and when the environment was wet. I fixed the misfire and cowling leak. Has not returned. I caulked the cowl and changed all my spark plugs and ignition coils.
View 3 RepliesBrand new to diesels with an 02 F250, 7.3 auto, 149k, 4R100. I have been hearing a whine (not the turbo...) for the last few days and after searching the web I'm freaked out about transmission issues. The whine is mostly present in gear while accelerating, I can slightly hear it in park/neutral as well. The sound is a little higher pitched than a power steering pump, pitch rises with acceleration but doesn't FALL as fast as the RPM with shifts, it lags for just a second then drops and starts the climb again with the next gear (i feel like this is indicative of something?). Runs fine and drives like what I would think is normal, only leak i see looks to be from valve covers making its way to everything. Transmission fluid looks great on the dipstick.
View 1 RepliesI 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 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 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.
