Golf IV / Jetta IV :: 2003 / 1.8t - Transmission Upshifts And Downshifts Really Bad
Aug 31, 2016
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?

2012 2.5 SE Auto 53,000 miles ... A few days ago I started getting very hard downshifts and long upshifts. The downshifts were hard enough that the person at the dealer didn't make it out of the parking lot on the test drive. Most noticeable from 3-2 and 2-1. 1-2 is hard and 2-3, 3-4 and 4-5 take a few seconds to happen. No lights or limp mode.
In recent months I was getting a thump about a second or two after coming to a stop. Enough of a thump that the car would move forward if I didn't have my foot firmly on the brake. They flashed something(the ECU?) claiming there was a TSB for my complaint but it didn't seem to make a difference. I bought the car with 40,000 and the trans never felt right to me. I had them change the fluid just before 50,000 so they couldn't deny a claimed based on failure to maintain.

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 .

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.

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.

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.

I've had my 03 VR6 6-speed for 12 years. It's been a second car for the last 5 or so, but regularly used. Friday morning the car got stuck in 3rd gear. The stick will only move from neutral position and down towards 4th gear. I've inspected the short shifter under the hood and the bushings under the shift boot. I did not find anything that diesel geek (the short shifter company) had me check for.
I brought the car into a local shop I have never used before (my usual shop closed), and today they called me saying its a transmission issue. I have not given them permission to open anything up. I am going to take the car home for now.
I have had to repair a broken 1-2 gear fork before. And at that time I had the 3-4 gear for replaced as well.
I should also mention, I similar issues on a quick drive i took the car on the night before. I thought it was just me acclimating to the shifter/lower power of the car as I hadn't driven it for a while. The point is, it drove fine afterwards and it drove fine for a 40 minute city drive to work the next morning.

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?

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.

Its been happening to me for a while now, but it seems to be more frequent. ill b driving around casually, go to pass someone or just accelerate hard then quickly up shift and get back on the throttle. I hear the engine begin to rev up again after the gear change but it takes a second or so until i feel the car continue accelerating. also i can feel the haldex system when it switches between fwd and awd or whatever it does. like you can hear it catch and def feel it lurch around. and clutch pedal vibrate a lot when any pressure is applied to it. is this normal?

Having downshift problems? The dealer has "flashed" the software 3 times and the hesitation still occurs.

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.

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.

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.

My 2011 toyota tacoma auto transmission downshifts on any slight decline, even to the point of losing traction in the rear end if I am on slippery pavement. How can I disable the electronic engine brake?

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.

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?

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?

Car is a 2001 Accent 1.6L 4 door automatic with about 130,000 miles on it.
Transmission shifts correctly into reverse, drive, neutral as well as manually shifting into 2nd and 1st. When in drive I will accelerate perfectly through 1st gear, shifts smoothly into 2nd gear then the problem arises. The car will shift ok into 3rd, but if I let off the gas to coast to a light or a corner, etc, the transmission physically downshifts or locks up in 3rd (like driving a stick, ie the car has drag like the converter is locked instead of freely coasting). It feels like 3rd gear but could be 2nd. When I go to accelerate again without coming to a stop the car has this same feeling of drag with no power and speeds up very slowly (almost like i am pulling something behind the car or am in a gear that is too high). If I give it enough gas to force a downshift it really slams that downshift. While the car accelerates through the rpm range after this downshift it will rev past the normal up-shift rpm until it finally slams into the higher gear. Or if i hold the gas steady at the higher rpm the car will suddenly slam into the higher gear. after all of this nonsense the car drives perfect through to OD. The problem is much worse going uphill and is consistent every time it is driven.
Also, sometimes the car would shake and vibrate when hitting the gas during this "drag feeling" until i let go and did it again. This is pretty random compared to the main problem but also seems to happen while the car is in 2nd or 3rd. This has been happening for about 5 months now and as far as i know was sudden. And on another note it suddenly was shifting fine the other day while driving it. I haven't driven it since then but this completely stumped me, as most problems will do when they magically disappear.
There is no check engine light, OD works fine and the car does not go into the safety mode where it will shift to 3rd gear on the highway. It's city driving that is the real headache (2nd and 3rd gear difficulties). Would the pulse generators cause this? bad TCM? i haven't scanned anything yet but will be within the next few days(at pep boys or similar) as well as ohming out pga and pgb. i have found resistance readings for pgb but nothing for pga, what should pga read? fluid is also within acceptable amount and color.
My initial thoughts were dirty or stuck solenoids/valves in the valve body and i was going to do a filter and fluid change with a quick valve body cleaning and check. But after researching on here I am starting to think it may be electrical. The only reason I put my scenario up is because it seems that everybody else who is having a similar problem is also having the "no reverse" or "shifting into 3rd on the highway" problems while i am not. On a random note, for my own piece of mind, how do the pulse generators work? Are they just reading ticks on a gear cog in the tranny or something? fluid flow?

I have a 2006 Chryler Town & Country with the 3.8L engine. The car has 170K miles on it and I change the fluids/filters as recommended. I have never changed the plugs and wires though, or the fuel filter. The car starts and idles normally, and no issues driving in-town or on the highway.
Recently I have noticed a loss of power when I give it more gas and the transmission downshifts. The engine revs up but the power doesn't really increase and it makes a low growling kind of sound. The engine also starts to hesitate at around 3000 RPM if I rev it in neutral. I am thinking it could be the plugs/wires, fuel filter or air filter (even though the air filter is less was installed at 163K miles.

My beloved Treg is marooned at the dealer again, having been towed there this morning. Transmission is all over the place...shifts into 5th and stays there, or extremely jerky shifts - especially downshifts. Gear position indicator is highlighted in red and no longer indicates which gear I'm in. Check engine light is on; no message in MFI...
Incidentally, it appears that the dealer and/or VWOA is starting to understand how to treat luxury vehicle buyers. Roadside assistance was very responsive and courteous. Dealer set me up with a rental from Budget...made a point to have me pick something similar to the Treg (not a POS econobox). I'm driving a Ford Exploder...a far cry from the Treg, but at least it's an SUV and has similar seating and hauling capacity.
