Passat (B6) :: Clunk / Rough Downshift From 4th To 3rd
My 3.6 4motion has a rough downshift, 4th to 3rd. I can feel the clunk. The service department (which has been otherwise great, at Gurley Leep in South Bend, IN) says it's "within specs." And no TSB. I know we've discussed the TSB for the rough downshift on the 2.0T. Anything on the 3.6 4motion?
View 3 RepliesFord F-150 (2004-2008) :: Slightly Rough Ride Around 70 - 80 Mph Sometimes On Interstate
I noticed a slightly rough ride around 70-80 mph sometimes on interstate a month back but thought it was my scalloped tires that need replacing and ignored it. Last weekend i had to go to MI from GA pulling a small enclosed tandem axle trailer (6x12). I started after work and made it to VA before stopping for the night with no problems not even at 70-80. Fueled up first thing in the morning (BP Fuel) and headed farther into the mountains when the truck started shaking when it should be downshifting (into overdrive I am guessing?)
No check engine light come on so i pulled off the road checked rear end and motor oil everything was fine, topped off tranny which was slightly low but was on dipstick .I let the truck cool for 20 min then got back going again. I continued driving with overdrive off, and not on the truck. Every time it had to downshift under hill climb it would start shaking but i would let out of the gas and it would stop. Once i got out of the mountains it was fine and couldnt tell it was running bad at low rpms, and also drove fine when i got off the interstate for fuel driving in towns.
I drove that whole day through ohio mich and back trough ohio when entering kentucky. It started to downshift and run at high rpms with no problem, and started acting up when i got back into the mountains.When the truck would go to downshift it started to shake uncontrollably again. then is when the check engine light come on and flashed. I babied in until tenn when i stopped at oriellys to hook up to scanner. scanner read misfire on 5 and ignition coil d primary secondary circuit malfunction. I checked the #5 plug (fine) and replaced the #4 coil, and didn't check the #4 plug.
t kept going and it never fixed the problem. stopped and jumped my coils around and check a few more plugs which all were fine but never that #4 (why idk), after being fed up, sat night, no mechanics around and wanting to get home i drove it the rest of the way. it never idled rough until i got almost home in Ga. When i got home the next day i pulled all plugs and all looked brand new still except the #4 which had the whole prong and tip completely burnt off. I replaced it and nothing changed, but my exhaust sounded restricted. Brought to a shop and it is now reading a misfire on 4 (with brand new plug) 5 7 and 8 and also saying it is running lean. They changed fuel filter and plugs but nothing still.

Phaeton :: Low RPM Cruising / Rough Downshift
My V8 NAR Phaeton started with a problem today which is exhibited at low RPM cruising. It is as if an invisible person is tapping the accelerator rhythmically. For example, when going 30MPH with my foot steady on the accelerator, the car will fluctuate between 1300rpm and 1600 rpm, and if I happen to brake during one of these surges I will experience a rough downshift. A complete VAG Com scan revealed nothing code-wise. the car seems to shift fine when accelerating, and according to the center display there are no gear shifts occurring when these RPM fluctuations occur. If I manually select a gear and cruise at a higher RPM, these fluctuations do not occur.
If my description is not clear, I could possibly post a video. I don't have much luck with the search function on this forum, just want to make sure this isn't a well known issue before I trouble with video.
The car is 2004, 113K miles. It has the original batteries which will be replaced in 2 weeks time, but I have not been having any electrical problems.
Passat (B5) :: 2002 - Brakes Drag / Smoking When Get Off The Interstate
I have an 02 Passat 1.8t that drags the brakes when I am driving to the point that they start smoking when I get off the interstate and my gas mileage is terrible. When I first observed this dragging I popped the hood and found that the check valve on the hose that connects to the end of the intake manifold had a chunk missing and was hissing. I did some research and found that this hose leads to the brake booster so i bought a new valve at the stealership and installed it and I am still having the issue.
I checked all the other hoses around that area and underneath the manifold for leaks and the only thing I found was a hole in the small hose that connects to the very front of the intake manifold that leads to the N249 thingy which i fixed but i haven't tested the brakes yet. When I start my car after it hasn't been on for a while my car does alright for about 10 minutes before the brakes start dragging again. Also pumping my brakes doesn't seem to work much.
Azera HG (2011-16) :: Rough Downshift When Slowing Down And Going From 3rd To 2nd Gear
When I'm slowing down, usually about 35 mph which i think is going from 3rd to 2nd gear, there is a noticeable rough down shift. Nothing horrible, but definitely much more noticeable than the shifting of all the other gears.

My 09 Sonata GLS has 50k miles on it. I bought it as a demo model with 9k on it (regret that) as new ... who knows how it was treated.
at 40k miles I noticed that in the morning when I was braking the car would feel like it was slipping out of gear momentarily and it was pretty rough. After a few minutes it would stop and I could continue on my way. The car is an automatic. I noticed it if I let the car decelerate enough that it dropped into first on its own, or if I used the brakes. I figured it must be due to the cold weather or something and was hoping it would clear up. This was only happening after 8 hours of non-use, overnight in the cold.
Sonata NF (2006-10) :: Rough Downshift While Coming To A Stop From About 20 Mph
My 2009 Sonata (4 Cyl.) has begun to downshift very rough while coming to a stop from about 20 mph. At first I thought it was the brakes, but now I'm convinced it's the transmission. Essentially it "jerks" a couple of times before stopping. It started happening at 30,000+ and only happens when transmission is still cold. Once I've driven for a bit it doesn't happen.

Had a slight shutter or jerking feeling in their LS, sort of like the rotors are warped, when they slow to a stop from 40+ MPH? I just cannot make the car stop smoothly no matter the amount of brake pressure I apply.
I can 100% eliminated the issue if I shift the car into neutral before I slow down. So it has to be the the transmission not downshifting smoothly. Done it from day one. I even replaced my rotors and brakes so I know that isn't it.
Honda - Accord :: 1998 - Rough Downshift Into First Gear When Come To A Complete Stop
I recently bought a 1998 Honda Accord with 124,000 miles. The car had one owner for 14 years. The carfax indicates the owner maintained service on the vehicle, but didn't go into detail about the work that was done. (only that the started had be replaced) When I come to a complete stop the car downshifts rough into first gear. It almost feels like it slightly jumps forward. Is this a problem I need to address and if so what is the problem? I bought it from a trusted dealership who had their mechanics give it a check and said nothing was wrong with it.
View 6 RepliesFord Ranger / B-Series :: Transmission Adjustment / Rough Downshift Into 2nd Gear About 15 Or 16 Mph
My 93' Ranger XLT extra cab 2wd, 4.0 engine and A4LD auto tranny with 126,600 miles has a rough downshift into 2nd gear about 15 or 16 mph. Down shift to 1st is real smooth and upshifting thru the gears is smooth. I just put a new modulator valve on it and upshifts smooth out, they were getting to be hard shifts before changing that valve. I do not know if there is any adjustment that can be made to smooth out the rough downshift when slowing down to a stop for red light. The U-joins are in good shape and new carrier bearing assembly on driveshaft and no extra play in the rear end. A band adjustment maybe or just have to live with it.
View 5 RepliesPassat (B6) :: Car Jerk And Clunk During The Downshift
I don't do too much long range driving but i notice about a week ago i was driving about 70mph for about 40 to 50 miles.. and when i got of at the exit i started to slow the car down and during the down shift i felt the car to a little jerk and clunk with a bit of hesitation during it.. Today i was doing another long trip and it did the same thing..
i use the highway a lot but usually on it for maybe 5 to 10 miles and it never does it.. I called the dealer and explained it to them and he said he would have to drive the car. and i know since it only happens on 40 plus mile trips the dealer isn't going to go for a test drive that long..
The next long trip i have might be tomorrow nite headed to AC for some gambling so i am going to try to remember to bring my camcorder so i can try to record it for the dealer..
car is a 07 wolfsburg 2.0t automatic completely stock..
Passat (B5) :: Jolt On Downshift While Decelerating
Every now and then (more often than not) when I am slowing down in my '05 GLX Passat, the transmission seems to throw it's self rather harshly down into first gear.
So, I'll be slowing down from an exit ramp off a highway to a traffic light and right before I come to a complete stop the car will jolt its self into first.
Is that normal? It happens more when I am slowing down at a quick rate, but when I am gradually slowing down, it usually won't happen.
Passat (B6) :: Tranny Downshift When Going Downhill While Braking
So my 4motion downshifts going downhill while braking...it's annoying as hell! My DSG used to do the same thing but being a faster tranny it was actually NOT annoying... Is there a way to reflash the tranny software? Maybe with an older code because my 06 didn't do this but my 08 does...
View 5 RepliesPassat (B6) :: When Floor The Car In 4th Gear It Will Automatically Downshift To 2nd Or 3rd
Is there a way to VAG-COM a 2006 B6 to hold gears in Tiptronic mode? What I mean is, if I floor the car in 4th gear, then the car will automatically still downshift to like 2nd or third. Is there a way to keep the tranny from behaving this way?
View 5 RepliesPassat (B6) :: 2.0T - Hard Downshift In Sports Mode
When driving in Sports mode only there is a hard downshift from 3rd to 2nd and or 2nd to 1st gear. It is very apparent when stepping on the brake to slow for a turn, the transmission downshifts causing the car to lurch forward (just like if you were to downshift badly on a manual). My car is a recent build 3/07. The car is undriveable in Sports mode at city speeds.
View 8 RepliesPassat (B7) :: 2013 - Engine Braking During Downshift?
About a month ago I bought a 2013 Passat TDI SE (with the automatic transmission) and have noticed that if you let off the accelerator in order to coast up to a stop light, the car will gradually decrease speed at a seemingly steady rate right up until about 15 MPH. Then you get an aggressive engine braking sensation and it feels like the car is about to come to a complete stop. After it drags down to about 10 MPH the braking feel will "release" and the car will lunge forward.
Is this normal? I have my re-check scheduled for this Saturday so I had planned to ask about it.
Passat (B6) :: Clunks Down Into Gear On Downshift Occasionally
My wife's been complaining off and on about a clunking noise with her '06 Passat 2.0T I couldn't get it to replicate; maybe three complaints on the last 10 months? I wrote it off to the transmission, as it occasionally clunks down into gear on downshift; done this since new, maybe twice per year.
Anyway, she just got the tires rotated last week. And oil change has been at the dealer last six months.
That's why I was shocked when I was changing the front pads tonight. I removed the left wheel, and a fractured sway bar was staring me in the face, end link dangling loose.. The brake was far from fresh...lots of rust and crust on the brake.
I can't see whether it was hit, other than the brake. Everything else looks good. I'm just floored that VW dealer, and especially Discount Tire, didn't catch this during routine work.
Passat (B6) :: Hard Downshift When Decelerating From Higher Speeds
So I've had my B6 7 months now with no major problems (other than a blown head light bulb, which was repaired under warranty) - until now....
So when I'm decelerating from higher speeds (55mph +)...say for a stop light or to turn....around 30mph....my car occasionally shifts down hard. Not enough to make me stop driving and call a tow truck but definitely enough to make me to notice.
It's only when shifting down and it's just started in the past month or so. Before that the car has performed beautifully...shifting like silk. My car is a 2007, auto 2.0T with almost 20k (had 4k when I bought it). It happens when I decel slow or have to stop real fast. It seems like there's no rhyme or reason to it.
