Ford - Aviator :: 2003 - Slight Stutter In Auto Shifting Between Gears
Aug 27, 2014
My 2003 Aviator kind of stutters when in auto between gears. Most prevalent from 3 to D when driving regular. If I shift manually and tach it to 4k there is no stutter/vibration. My engine light is on and pretty sure the catalytic converter need to be changed. All new NKG plugs and associated coils. Throttle body clean, 91+ fuel only. Could this me a tranny starting to fail or computer/senor related? No other codes than the bank-2 O2 sensor....

I am having issues with a 2006 Gen II Prius that just approached 120K miles. When going down a hill at approx. 35-40mph, the engine jerks when downshifting or when coasting.

I bought the car about a week ago, whenever the auto tranny shifts gears there is a slight jerk that old honda autos are known for, my wife's car is a 01 celica gt which I bought 2 months ago and went through castrol import ATF 3x drain n refill method suggested by honda for their auto trany, I attempted the same thing in the gts and the shift jerk went down a little but not by much, the gt auto tranny is so smooth I can't even tell whenever it shifts up or down other then high rpm engine noise when it gets there. Is it the engine being much more powerful then the gt to cause that jerk? Should I try a different fluid? Need to know if theirs is smooth across all gears in any rpm range.

I have a 97 4runner Automatic that as your driving it hesitates between shifting its gears. Most prominently happens around 80km/hr shifting between gears.
Its a sort of soft sputtering/jerking motion momentarily. It does shift into the gear and does drive fine once its in the gear. My check engine light is on as well now....

We have a 2004 Aviator AWD. 73k miles. Trans has been shuddering on the upshift to OD intermittantly. No codes no other symptoms.
I dropped the pan, replaced the filter and 5-6 quarts of fluid with Mercron V fluid. No metal in pan, fluid was not burned, filter only had a small amount of dirt. Very small amount (fine dust)of metal on the magnet. Drove it about 50 miles and noticed the shudder again this morning. I planned on replacing the fluid in the pan again after some miles and time so as to get most of the 12 or so quarts replaced.
I have no codes or CEL. No flashing OD light either...

My friends truck is having a problem, and I haven't found any info on the specific issue. when you shift from P to D and accelerate, there's a slight grinding clatter in the tranny i think, bump it to 2 and the noise is completely gone! pull it to 1, and there she is again, also in reverse it does this, speed is not a factor, only the specific gears. i had read a thread which mentioned a "sun gear", and also that 1st and R are on the same bands?
I believe it was for a manual tranny that I had read about, but what this could be?! he's got a slight drag on the rear brakes, i assume it's his E-brake, could that have caused a transmission failure? We've removed the driveshaft and checked u-joints and all, nothing there, but when the truck reverses on the ground, you can watch the driveshaft bounce like it's binding. We grease the slip joint while we had it off, and we were able to spin the rear wheels by turning driveshaft w no problem while off the ground.

From the other users it seems that almost all are having slipping of gears and rough shifting associated with this code. On mine I'm not getting any slipping or rough shifting...it actually still seems to be driving just fine. The OD light came on and will go away after shutting the truck off and back on...it will then not flash anymore for say a couple of months or so...this has been happening for the past few years every now and again and i never thought much of it. I just made a 2k mile trip and this happened again but this time it threw the p0775 code which is a first.. Is it possibly a very early sign of the sensors going bad.

I have a 2000 F350 7.3 213,000 miles. Manual tranny, 2wd. It is my daily driver.
No issues until 2 weeks ago I pulled out and began shift gears when the engine died and I completely lose pedal. The engine does not shut off it goes to idle and the lights and power are fine but I quickly lose acceleration. After a couple seconds and a few pumps on the pedal it comes back. The problem is intermittant. Until yesterday it was only in the morning but then happened on the way home from work. Thinking ti was water in the fuel I used an additive to cure the water.
I changed the fuel filter just after I bought it in April of this year. I know there is a Injector Pressure Sensor that could be the culprit. EGR?

(2000 F-350, 7.3L, 205k miles) Over this weekend, I noticed while driving mostly in the lower gears, that there was a slight hesitation with the throttle pedal depressed about half way or less. Seem to get worse as the day went by, but no lights or anything came on. Changed the fuel filter and added a fuel injection cleaner to the tank. Checked the oil and it was low, so I filled it to the correct amount.
Drove it around the next day, and it seemed to be good, until it warmed up some, and continued to hesitate. The hesitation seems as if it's not getting constant fuel, and the truck jerks a little. Once you get up to over 2000 rpms, it goes away. Looking up other reviews on similar issues, most have pointed to the throttle pedal sensor and just changed out the pedal assembly. Before I take it that far, I wanted to see what was the corrective action.

I'm fully equipped with apr stage 2 with all the hardware (carbonio intake and full apr turbo back exhaust). So anyways everytime I'm in the higher gears (3-6) I get this rpm lag/stutter, what the issue can be...
Here's a link to the video on YouTube of what's going on [URL] .....

I have noticed a slight stutter in the acceleration when pushing it hard. Seems to be most noticeable 4th gear around 4500-5500 rpm. Is that because I dont have a HPFP? I also notice the fluttery whistle sound that was discussed at length in another thread...doesn't bother me one bit but it seems to coincide the stuttery acceleration. Also, I noticed it upon the very first drive after getting flashed - currently at 2500km.

I have a 2003 Lincoln aviator with the 4.6 V-8. When I was seafoaming the car today, afterwards I noticed the truck running a bit rougher, and the truck idles around 500-600 rpms instead of 900-1200 rpms. There was a hose connected to the left valve cover, I pulled it off and there was no change in power or sound or idle. Is the hose a pcv hose, if so, where is the valve on this engine in the aviator, shouldn't it be on the valve cover? Do you think its a vacuum leak cause by the pcv valve/hose or a vacuum leak somewhere else? does aviator 4,6 come with a valve or just a pcv hose?

For those of you tuned and deleted......intermittent transmission shifting stutter is gone now? Mine sure is. Never once since the mods have I had that annoying stutter when the truck is cold and I'm easy on throttle between 2nd and 3rd gears. What a relief it is to have it shift NORMAL ALL THE TIME!!! Stutter no more after H&S Tune and Delete, for about two months now.

I have an 03 Aviator with the full-time AWD with about 138,000 miles on the odometer. The truck is reliable and I love it, but I keep noticing a shake and vibration going on, I notice it at almost any speed, I'm pretty sure it gets worse at high speeds and when braking ( especially at high speeds). would this be a transmission problem, a bad cv or u joint? or would it be bad tires or wheel bearings? shocks/struts, rotors?

Last 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.

I have an '03 Aviator that has this really odd stumble / shutter while driving down the road. It loses power and feels like it is going to stall. This is very intermittent and not obvious at idle. Sometimes on hills, sometimes just cruising along. I did some reading and thought maybe I had an ignition coil(s) going bad.
I took the covers off the coils and pulled them out. Six of them looked perfect with one being newly replaced by Ford. Two of them had a thin film of oil mist on them both outside on the rubber boot and inside the rubber boot. I wiped them off and put them back in. There was no oil down in the plug bores and the valve cover gasket looked good. The plugs looked good too.
Is there any way to actually test these? If the problem is intermittent I am not sure if they would fail a test until they got hot from use. I do not have any lights or codes.

I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?

I'm new to owning an ISF. I purchased it almost two months ago and couldn't be more happy with it. I know after owning a car you will start to notice more and more about the car. About a month into owning the car I was on my way to work and I stopped at a light. I noticed that there was a very slight shutter at idle. No where near the shutter if it was missing on a spark plug. After that day it has drawn my attention whenever I stop.
My question is is this normal? I know having a V8 in the car there is going to be some vibration. It's a 2009 with 29k.

I just picked up a Sport. I've noticed 1,2 quick stutter type thing happening intermittently at highway speed going up a hill. Dealer service probably won't be able to have it happen as it only has happened 3 times in my 400 miles.
