Golf IV / Jetta IV :: 2003 / 1.8t - Transmission Upshifts And Downshifts Really Bad
I bought a 2003 Jetta with a 5 speed automatic transmission (09A tiptronic) but it upshifts and downshifts really bad, it doesn't matter if it's cold or warm. After reading a lot of posts in here I thought that what was wrong with the car was the valve body on it, so I bough a re-manufactured valve body and replaced the old one. When it was in the shop I was told the wiring harness was burnt/fried so they replaced the harness too. I got the car back and it still does the exact same thing, so I don't know if the transmission is bad or maybe it can be a bad TCM. What could be wrong with it?
View 3 RepliesGolf/GTI VII :: Quick Upshifts / Slow Downshifts With Hesitation
Seems like the engine and transmission are talking through Google Translate. The usual problems: too quick upshifts, too slow downshifts, lugging and vibration at RPM too low for road speed around town, hesitation. Aware this all supposedly support mileage but it's putting a rough edge on an otherwise quiet and likeable car. In fact, mileage seems to be suffering a bit. Aware there's a TSB on the 6AT that supposedly cures this via a software update .

I have a 2006 Passat that I love but it's been doing something since it was new that has finally bothered me enough to do something about it. When the automatic transmission upshifts from 1st to 2nd, it feels really jerky - I don't know how else to describe it. It's like it surges and other times feels chunky. It seems worse after the car has sat overnight or during the day at work however it still does it even after being warmed up - just not as severely.
I called my VW dealership and spoke with a service rep and he suggested allowing the car to warm up for a few minutes before driving to let the transmission fluid 'pump' or something - not exactly confidence inspiring and even if that worked, not a good solution. The good news is that it doesn't work any better after doing that so I suspect something is actually wrong and hoping they will find it before it gets worse. I have an oil change this Thursday but based on my discussion with the service manager, I don't know that I am going to get very far with them.
Jetta - Volkswagen :: Transmission Downshifts To 1st When Come To Hard Stop
My 2004 VW jetta has 139k on it. Whenever I come to a hard-ish stop or almost-stop, the transmission downshifts to 1st and won't get out of it unless i play with the tiptronic mode selector and coax it to upshift. it shifts well and works well in gingerly driving other than in this circumstance. i took it to a shop and they say (as they always do) it needs a new tranny. I'm wondering out loud if there is some kind of mounting instability issue that could explain this. This is definitely a case of needing a new transmission. I have read a bunch about solenoids being the culprit in general shifting problems, but not this exact set of symptoms and circumstances.
View 1 RepliesCorolla / Matrix 2009-13 :: Transmission Shifting Extremely Hard When Downshifts To Make A Pass
The transmission is shifting extremely hard when it downshifts to make a pass.
Any other time it shifts fine, this is the only scenario it happens in.
It is pretty violent, shifting with a bang.
It is a 2010 corolla, auto, with 70k miles, I have never changed the fluid, and I don't think it has anything to do with it.
The tech said it might be the battery, as it was going bad. I put a new battery in, and it didn't seem to do it for two weeks or so, but is now back doing it again.
Passat (B5) :: 1998 - PRND321 Lights Illuminated All The Time And Downshifts Hard Into 1st Gear
I have a 1998 Passat 4cyl turbo. Recently the ICM module on the air box went out when I had No Fire on 2nd cyl from the front. Replaced it with a MPGauto part for $63. It fixed the problem but, I noticed that now the PRND321 lights are luminated all the time and downshifts hard into 1st gear. Also should I be concerned that I need another catalytic converter b/c I drove another 40 miles with it missing and it (CC) was very hot. Do they break down inside? The car runs great. Is my problem related to this china part not having a special VW code or can the car be reset?

Lately my '03 1.8t with 90k has taken to long cranking before firing.Once it fires, it runs rough for about two seconds and then smooth as usual. Thought it might be Fuel pump relay but I'd think that'd show a fault light. Same with Fuel pump?No faults showing up. Plugs changed 9k ago. Only run Premium Shell.
View 1 RepliesTouareg :: V8 Transmission Lurching Forward On Upshifts Under Moderate Acceleration
I've been told by my dealer that the 6-speed transmission in our rigs is known to shift roughly. They have therefore pronounced my truck healthy. However, I don't think I believe it. I've never seen a vehicle that lurched forward on upshifts under moderate acceleration. It behaves if I punch it. It behaves if I accelerate like my granny. Anything in between and I get a fairly violent jump at each shift point. At times, in stop-and-go traffice, I have thought the truck would jump into the car ahead of me. This behavior seems to be unrelated to which transmission mode I'm in. D, S, and Tip all do it. I love the motor in this thing, but I'm starting to hate the tranny. What should I tell the dealer to look for on the truck that might be causing this? The truck is going in next week to replace a fog light with condensation, so I'm hoping to get them to look at it then.
View 1 RepliesCorolla / Matrix 2009-13 :: 2010 LE Transmission Upshifts If Foot Off Gas At Highway Speeds
Is this behavior normal: I test drove a 2010 corolla LE with 4-spd auto, 41K miles. Noticed that on level highway 60 mph that whenever I eased up on the gas that the RPMs would shoot down. Vehicle speed was barely decelerating since I was on level. As soon as gas reapplied (gently), then the RPMs would shoot up. I'm guessing the delta was like 300 RPM. I get the impression that at highway speeds the car is mostly in 3rd gear or shifting up and down a lot. I've read a lot about a TSB for 2011 corollas but nothing for 2010. And I think that problem is different. So my question is whether this is "normal" for driving at highway speeds?
View 5 RepliesSubaru - Forester :: 2009 - Transmission Vibrations Going Over Rumble Strips When Upshifts From 3rd To 4th Gear
I have a 09 Subaru Forester with 66k miles that vibrates like it is going over rumble strips when it up shifts from 3rd to 4th gear. It occurs under normal (not brisk) acceleration. I had the trans fluid changed at both the 30k and 60k services. I have owned this since new. It began before the 60k service. Also, sometimes the tach will increase revs during this as well. I don't know if this next thing is related but when I once need to merge quickly into interstate traffic I gave it a good amount of throttle and the tach revs increased but the trans did not follow with an immediate down shift.

View 11 RepliesCamry :: 2010 - Transmission Downshifts While Slowing Down?
I am getting to the point with this car that I can't stand driving it This thing where the transmission downshifts as I slow down and come to a red light is the most obnoxious feeling I've ever experienced in a car. What's worse, is when I go to speed up again and it's in the middle of one of its downshifts and hick up so bad it feels like it's can fall out of the bottom of the car. I'm done trying to deal with Toyota dealerships, all they do is tell me that Toyotas don't have transmission problems and that my car is fine unless it kicks on a light.
I feel like if this transmission was reprogrammed to act more like a normal transmission Like the electronically controlled transmission that was in the 1995 Alexis that I sold a few months ago, or my wife's 2006 solara or the 2008 I asked to 50 I used to have, the car would be fine. But this thing is neurotic, jerky, and unpredictable.
Elantra MD (2010-15) :: 2011 - Rough When Dropped Into Gear / Up Shift And Downshifts Equally Hard
Drove to work today and all was fine. Came out at 3 and started my Elantra up, dropped it into gear and it was ROUGH. Engine ran for a few seconds before I put it in gear. The shifts up the street were hard and the downshifts were equally hard. I put the transmission in manual--same thing. After a few minutes, the shifts returned to normal. No CEL. The car has 48,700 miles on it.

We have a 2007 Limited that we love everything about except the way the transmission downshifts to first gear when it seems to me it should stay in second. My inlaws have a 2007 XLS and it doesn't do this. This is our third Avalon and the only one to do this. The dealer we bought from says this is normal but I strongly disagree. Is there a service bulletin on this or what else can be done.
View 2 RepliesIS F (2008-2014) :: Transmission Downshifts Automatically To 5th Gear
I've noticed lately in auto mode (not in sport mode) when I'm going downhill on a section (doing maybe 45-50 mph) of road and apply the brakes, the transmission wants to downshift automatically to 5th gear. I know in Sport mode if you are not using paddle shifters this seems normal. I don't think this is normal in just auto mode, non sport.
I don't think mine is normal as I don't remember it downshifting this much in auto mode. I'm thinking fluid level needs to be checked. I know there is a sensor in the transmission that senses the angle of the car so not sure if it's being overly aggressive or not.

If I understand correctly my 2004 Expedition has the 4R75E transmission. We are experiencing a clunk upon acceleration when the truck downshifts from 4th to 2nd. I had the fluid & filter changed, flushed the transmission with cleaner. It still does it but not all the time. I turned OD off and I didn't notice the problem when shifting from 3 to 2.
View 1 RepliesFord Transmission :: R4100 Downshifts When Going From 2nd To 3rd - Code P0781
2001 expedition, 198,000 miles. Got p0781 code ,1-2 shift error. replaced the accumulator valve with a factory tech valve body. Pan was clean, some gray material on the magnet but not bad. 1-2 worked fine after vacuum swap, but when trying to shift from 2nd to 3rd gear, the transmission downshifts hard all the way to a stop, like the brakes are on.
I can manually drive in 1st and and 2nd but when I put it in drive it will downshift/brake instead of shifting from 2nd to 3rd. pulled the main valve body and 2-3 and 3-4 shift valves seem good, no sticking. 3 other valves were sticking. i think they are the Solenoid regulator valve , and coast clutch shift valve, and low/rev modulator. Could they be causing the hard downshift/braking?
Camry 2012+ :: Coasting To A Stop And Speed Gets To About 27 MPH - Transmission Downshifts
I've noticed that when I'm coasting to a stop and my speed gets to about 27 MPH, the transmission downshifts (RPMs increase) until I reach about 22 MPH. I'm not applying the brakes at the time.
It's a bit annoying as it sometimes bleeds off just enough speed that I need to accelerate to reach the point I was planning to stop at. Is this normal?
