I have a '99 E350 Ford van, V10, with 300K that runs like a charm until I slow down to stop. It begins to surge which will stop when I shift to neutral. I went to the local parts store and put it on their code reader. It only read 'left bank lean'. Nothing else.
View 5 RepliesThe car is an '05 elantra, 97,000 miles, auto., car is new to me. First time on the freeway today, 30 miles @75-85 mph, at the end of the off ramp I could feel it surging, shift to neutral rpm's went to 1500, hoss the gas and back to normal. On the return trip off ramp, went to neutral, jab the gas, everything OK. I'm going to clean the throttle blade, check things, etc.
View 3 RepliesIs it ok to put it on Neutral while I'm on stop, stop light, etc. while the engine is running? I have an Automatic....
View 8 RepliesOn a manual car, I know it's not the best thing to go from neutral, completely bypass 1st gear, and shift to 2nd gear. As well as 3rd to 5th bypassing 4th. However, is it the same for downshifting into neutral or another gear? Will it hurt the transmission to go from 3rd to neutral (bypassing 1st and 2nd) when coming to a stop? I do know that shifting from 4th to 2nd gear and bypassing 3rd will harm your tranny. I just want to double check if I'm right...

2007 E350 with 5.4L and 4R70W trans. 107K miles and the fluid has probably never been changed ( my mistake - thought it was 100K interval - finding out from my reading that is def not true ). Anyway, following is recent development (last couple days):
Symptom #1: In Park/Neutral there is a whine. As soon as you put it in P or N, the whine 'spins up', stabilizes, and does increase with engine RPM.
Symptom #2: Hesitation (albeit minor) when starting from stop in D and R, with _very_ minor shudder. Sometimes feels like it's struggling a bit to move its own weight just until it's rolling.
Symptom #3: Shudder when accelerating in OD. No shudder when I turn off OD. It does not stop when applying brakes (a test suggested elsewhere). Also, the shudder does not happen when applying gas while braked in D at standstill. Only at highway speeds (enough to be in OD).
This all started at the end of a trip (90 miles or so in 85-90 degrees) when I was pulling a utility trailer (maybe 2000 lbs loaded). Not sure if related, but traction control warning went off a couple times. I think I have a axle seal leak that may be triggering that.
Otherwise shifts fine (no change in shift behavior or smoothness). Things seem to be worse when it has heated up. Should I start with a fluid change? Wasn't sure because there are comments out there saying don't do it or the tranny will just fail faster (I am skeptical).
My truck is making this chattering when I shift down or just sitting there in neutral it goes away when I press the clutch or if I push the shifter in the spot before the gear I was told it was a throw out baring but I'm not sure I herd this transmission will start to chatter before it goes out so what to do?

How the auto gear shift works on a ford E350.Does it work by wires or does it have a steel column to change the gears.I have looked for pictures but with no luck. I have spent 2 hours looking.
View 4 RepliesI have a 99 f350 V10 gas dually dumper. Today while driving I stopped at a stop sign. When I went to continue the transmission seemed to be in neutral, then it caught and I drove through the intersection. It 2-3 seconds later disengaged again. I pulled over. When I attempted to put it in park it grinded. (Bad enough I just turned off the key). I checked the fluid. It was close to full and red. While in park I restarted. Truck started fine. I shifted into drive and nothing. It was like it was in neutral still. I attempted to put in park again and more grinding. Also while in park it does not hold the truck from rolling. After getting towed home I checked the tranny fluid again and it was still looking ok. I drained the transfer case also. The fluid in there was near black an appeared to have a metallic look. Does this problem seem to be just my tc or tranny issues also?
View 8 RepliesWhat is happening is that air will stop blowing through the vents randomly. We will be trucking a long with either a/c or heater on and all of the suddon it will stop blowing. I know the blower is on because I can toggle between vent and defrost. It will blow out of the defrost but will not through the vents. It can be anywhere from 1 to 10 minutes and all the sudden it will start blowing through the vents once again. It just doesn't blow through the vents. This is a 1992 E-350 with a 460 in it.
View 3 RepliesI have problem with an occasional stall that occurs when the engine is warm and slowing to a stop. I have a 1994 fuel injected E-350 460ci motor home. The engine runs great 90% of the time. When cold or sitting the vehicle will start and idle great. After warming up 5-100 miles occasionally I will slow down to stop, the rmps will fluctuate from 400 to 750 rpm as will the vacuum then die. The engine will start up fine but idle roughly wanting to die again during this period. Once the rpms are above 1000 and put into gear the engine will take off and accelerate great. This stalling tendency will last about 15 minutes (if I stop) then appear to go away and not reoccur during that trip.
At high speed and hill climbing the engine does great. It has occurred once on each of my last 4 trips. I have had suggestions about: the fuel pump, fuel pressure regulator, and possibly the crank sensor. I'm trying to figure the best sequence on working this problem up. It might be tough in that the problem seems to go away after about 15 minutes regardless if the engine sits or is run.A few more notes: the rpm and vacuum are great and steady until the problem kicks in. Last summer a shop replaced: the computer, alternator, spark plugs, egr valve, and fuel filter. I think the parts were just replaced till the problem resolved. The problem (unrelated) seemed to be resolved after the work was done though.
1991 Honda Accord DX A/T A/C. The engine is surging/searching at idle in park and in neutral from 1000 up to 2400. There are no engine fault codes.
I have cleaned the IAC, adjusted the TPS, Removed/Cleaned/Re-installed the TB, No MAP problem. I also removed the "black box" and checked the cold idle control diaphragm as best I could. I cannot find any specs on testing this. When I apply vacuum to it via the center port on the bottom it holds the vacuum, but takes approx 5 seconds for the diaphragm to "pop" to its ambient state after releasing vacuum.
I have sprayed all possible vacuum hoses along with all intake gaskets to test for vacuum leaks.
I have attached a diagram of the black smog box that is mounted on the firewall. The cold idle diaphragm is labeled as 2. I also have concerns about that electrical vacuum solenoid labeled 27.
I took my truck in for a clunking noise in the driveline as I come to a stop and sometimes when shift into park. It is now the 7th and I'm told parts have been ordered and the truck will be worked on when parts come in. I asked to speak to general manager and still no call back. I called customer relations and nothing they can do.
Honestly I think the have me on the back burner since I'm warranty work opposed to marked up repairs. Am I being unreasonable on my expectations of repair time? I called around and a ring and pinion job is quoted at 3 days at the most. Other repairs have been approved as well and parts are in for those, but they have not actually repaired them either.
So, in my 99 Bounder RV (F53 chassis), V10
I think it has a 4R100 transmission in it (I have not verified this).
I had the oil and filter changed about 10K ago.
Runs and shifts fine .... then I stop and idle with it in gear (say stopped in traffic for a few minutes).
Now the thing shifts super hard! I actually get rubber in all gears.
So I pull over, shut it off. Restart the unit and everything is fine again.
It does this very consistently!
I went to the local transmission shop. They said with 110K in an RV it could be anything and I should think about letting them rebuild it.
Now that is something I would do ... not diagnose a problem and just rebuild it. I thought a "professional" would actually look for the problem first.
I don't want to rebuild the transmission if there is small item that will fix this.
I need to solve tranny problem, it started out a while back, would not shift back into drive after stopping at stop sign (after driving fine for about 20 miles) thought maybe dirty filter so did fluid and filter change seemed to work for a while then started again noticed it was mostly after using cruise control, but u joints were very bad, so replaced 2 of the 3 and worked fine for about a thousand highway miles, then got really bad. Now when I check the tranny fluid cold and /or hot it is way up on the dipstick. Took to ford dealer in ladoga, lied and said no speed sensor codes, but list on the paper he gave me had all kinds of abs and a p500 code.
View 9 RepliesThis may be an old question: is it beneficial to shift into neutral while coming to a stop in an automatic transmission? But, my new Ford Fiesta has a PowerShift 6-speed transmission that behaves differently from a standard automatic. According to Ford, it's "like two 3-speed manual transmissions put together, with the dual clutch and shifting components controlled electronically."
Since the PowerShift is really a computer-controlled manual transmission (without a fluid torque converter), it's actually in neutral when I'm stopped and the shifter is in Drive position. I can feel it disengage as I come to a stop. However if I try coasting to a stop uphill, the engine still pulls the car upward at low speed without my foot on the accelerator. So the computer has to judge when to activate the clutch.
The issue is, I tend to apply the brakes lighter than average and decrease speed at a slower rate to come to a stop. So I think I might be confusing the computer, working against the engine before it wants to disengage the clutch, whereas most people would come to a stop more abruptly and the shifting action would have no problem. This is why I shift into neutral early in my slow-down phase, so the engine doesn't have a chance of pushing the brakes.
I was told by the dealer it would be over 150 to scan and do a fuel trim on my 02 Explorer, XLT, 4.0, Auto. I can't afford the scan or a garage. I paid 4200 for it and a short time later it starts surging at stop lights then it starts sputtering when idling and taking a while to start. Next it stops accelerating past 2.5k, then works well a bit then stops accelerating past 50 miles an hour. Then it works with an 02 disconnected then starts acting up again. It now either runs normal, wont accelorate past certain ranges, or starts then quits 3 seconds later, unless I unplug the MAF then it runs 15 seconds then stalls. Through all this symptoms come and go. Always banks 1 and 2 lean.

I have a 2009 F150 4x4, XLT crew 6.5' bed, 5.4 engine. The truck has a very strange erratic throttle behavior from a dead stop through low speeds, shifting seems very strange at low speeds too.
Dealer tried re-flashing the computer, but that didn't fix it. They talk about some valve that sounds to me like it's similar to an EGR function, but I cant remember what he called this valve. He explained the issue as exhaust gasses that are to be recirculated and burned, but the valve is opening at the wrong time, or stuck open or something so it feeds the fire so to speak.
Does any of this sound typical or common? Is this something that's hopefully easier to do than a spark plug change on a 5.4?
I have a 1970 f250 with a factory 390 (vin verified) and a C6, I believe the transmission was rebuilt but have no way to verify. It works fine while cold and mildly warm. Once heat soaked it is very slow to shift (going from neutral to reverse can take almost 30 sec) and leaks profusely from the front. I can not tell exactly where the leak is. Could this be a case of just having too much fluid or is there a more serious concern? The dipstick does read high but level ground in my area is hard to come by so the accuracy can be questioned. If it does have to much fluid, do I just drain the pan, re-install and let it run till hot and replace fluid as needed or should I drain and replace with 3 qrts prior to starting?
View 7 RepliesDaughters explorer sport trac, needed a neutral safety switch and a fuse ( no reverse lights),, I have replaced both but now the shifter doesn't line up right.
P is now reverse, and cant get all the way over to 1 with out holding it...
the two marks in the switch line up for neutral.... and switch is keyed to shaft...
how do i now re align this so shift indicator and transmission are on the same page again??
I am guessing move tranny arm all the way to the rear of the truck position and put shifter in P....then put cable back on arm.... but doesn't seem to work ....
4R70W. This one is in my 99 F-150 with the 4.6. From what the previous owner told me this trans only has 13k miles on the rebuild and I believe him because the converter is bright blue and when it does shift right, the shifts are solid and fluid is very clean. Truck only has 98k miles on the body as well, so it's possible the truck did sit a while because my tires have a ton of tread on them, but they are dry rotted a bit (dated 2006 IIRC).
Issue: When the trans is cold (sat overnight) it will shift to neutral between the 2-3 shift for 1-3 seconds depending on outside temperature and then drop into gear. But it only does this for the first 30 seconds or so of driving, after that it shifts normal (although it does seem to hold gears a little longer than I would think it should on occasion and not upshift). I have only gotten it to do it once per cold start so it seems like once the trans gets any heat it's fine.
I was also thinking I was getting drain back and maybe it wasn't heat related so I dropped the pan, replaced the filter, fluid and pan seal (it had a small leak) and torqued the valve body. Two of the bolts were a little loose, but the rest were fine. Tightened them to spec and put it back together with no dice. Truck also gets pretty bad fuel mileage so I'm starting to think maybe there is some temp sensor screwing everything up?
I have a 2003 Ford Focus with the Zetec 2L, 16 valve. When the car is warm and I put it in neutral or park and take my foot off of the brake it will occasionally shut off. Not stall, but shut off - as though I turned the key. This doesn't happen every time; it usually doesn't. I have no other drivability problems and there are no warning lights or engine codes. The ideas I have are:
- Vacuum/ brake booster leak
- MAF problem or dirty throttle body
- Something weird going on with the transmission shift interlock mechanism.
