Phaeton :: Hard To Downshift From 3rd To 2nd Gear
Feb 22, 2008
I really do love the Phaeon and experienced a hard downshift from 3 to 2 when slowing at certain speeds. The trans is very smooth on the way up but if a let it coast down to zero while applying light brake pressure I get a hard shift from 3 to 2. It is currently at the dealer for service and they have checked everything and state I should just watch for it. They checked all the TSB's, fluids, etc. I wouldn't mind if I knew this was normal for the Phaeton.

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.

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.

My 2010, 4 cyl. auto started giving me hard downshifts awhile ago, when cold. Mainly going from 4 to 3, and 3 to 2. I had the tranny fluid changed a few months ago at 56,000 miles, but no difference. So, that left me with the dealer and this is their diagnosis:
Updated ECM and TCM and hard shift still present. Vehicle will require new PCM (TCM?) to resolve problem.

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.

My car also had the hard downshift when engine was cold and under 30mph. I seen where Sbr 711 had posted the TSB 10-AT-007-1
I printed this and took to the local dealer & also showed where it was mentioned as a recall.. The advisor looked up on his computer and showed no recalls for the 09 sonata?
I went ahead and scheduled the reprogram update and was told the technician can pull up more info on recalls than the advisor can? Any way they did the reprogram today and $89. later still no recall? How do I prove that in fact this is a recall & get refunded?

I have a 2004 Pontiac Montana minivan. I get a hard downshift from 2nd to 1st only when the engine is cold - especially noticeable in cold weather. After a mile or so of driving (or a few minutes of idling) is shifts fine. All upshifts are fine all the time. The tranny fluid level is fine and is in good condition. What it could be?

2000 5.4 4x4. 104k miles. Extended cab. Heres the issue, when you're at that spot on a slight upgrade and the tranny should down shift out of overdrive it will downshift kinda hard. Sometimes it does this and sometimes it wont. Its driving me nuts. I thought maybe change the fluid and filter and see what happens, but a tranny guy that I don't know from the other guy said dont waste your money its more than likely a broken spring behind a piston. I put a new motor in this truck about 10k ago so I can wrench. It did this before the motor swap too.

Recently started experiencing a hard downshift after driving for 30 minutes, and only from 2nd to 1st. No other shift issues with other gears, up or down.
When moving over to manual shifting, it doesn't appear to have the issue when downshifting in manual.
I replaced the radiator about 2 weeks ago due to a serious leak, and the shifting problem wasn't an issue before as I would have noticed.
Going to start with the fluid lvl, but it feels odds with it occurring during the downshift to 1st.

I have 2010 Sonata with 4 cylinder engine and 50,000 miles. For a while now, my car has a real hard downshift at around 20mph. When i put the car in shiftronics mode and do not downshift manually, at the 20mph hard downshift the car is shifting from 4th to 3rd. A while back i had the TSB for hard downshift and also did a tranny fluid flush. Neither has seemed to solve the problem.
Also, the car has a annoying electrical hum/whine that is coming from the engine bay. When i shift car into neutral the hum/whine goes away. Also sometimes when shifting into lower gears the hum/whine will go away for a short period of time.

My girlfriend has a 2002 passat 1.8t with the tiptronic tranny... its not throwing a cel but while driving in regular drive mode it seems to have problems downshifting... not all the time but sometimes when you get on the gas and the tranny downshifts it slams* the whole car...
The only thing i can describe it as, is being in a manual car and just dropping the clutch in a lower gear with out giving it some gas to match the rpm's... brought the car to vw dealers and such but all say nothing is wrong and it is "normal"...

Strange condition? If I kick it down hard into passing gear (or downshift hard into any gear for that matter), it pukes and sputters for a few seconds before clearing up and coming to life. No issues with normal driving, or dead stop hard acceleration, just on the downshift.
I’ve got a Magnaflow cat back on there and am wondering if opening up the exhaust and reducing the back pressure is screwing with the ECU a little? Is this just the nature of the stock Ford tune and it wasn’t as pronounced with the stock exhaust as it is now? Trucks an '06 FX4 5.4L and only has 70,000km on it.

So i just noticed this issue the other day. If I downshift from 6th to 5th the car hesitates before it starts to accelerate, this only happens for 5th every other gear is fine. This only happens downshifting from 6th to 5th. What is going on?

The car is a 2010 Corolla S with about 85K miles, I bought used in Jan 2015. This problem mostly happens when I am using the cruise control. I will be going up a hill at about 65 and regularly but not always the trany will downshift with a very hard "bang" like running over a pipe. It will make the shifts in a normal smooth manner at other times going up hills in cruise control. This hard shift is very abrupt and startling if not ready for it. In can do this when not in cruise control if at highway speed in accelerate to pass but not as consistent. It has not done it at in town driving.
I took it to the dealer, as I had a warranty, and took the tech for a ride so he could feel it. I was told the next day the warranty company says this is "normal" behavior. I do not believe this to be normal.

I have an 2011 6.7 that has a h&s tuner. Lately my transmission seems to be confused about what gear it should be in when I'm driving about 45mph. It will sometime downshift hard. I have a early build 2011 and heard that it could be a solenoid problem with the transmission.

I have a 99 Ranger, 3.0 xlt 2WD Automatic 5r55e(???) tranny (i know its the 5). I have the o/d off light flashing. It comes on when fluid gets to op temp. When on it shifts hard into 2nd and hard when it downshifts. No slipping. I have had the truck in the tranny shop for 3 weeks, owner said he re built valve body gasket (didnt work) tried 3 diff used tranny's (didn't work) or so he says. He said it needs to be rebuilt.
I have searched up and down for what it could be, there is so much out there, it only confused me more. If i have to rebuild i will, i think the tranny shop was pulling my leg (for more reasons than mentioned). I have a check engine light on nothing to do with tranny...there is a tranny code, he would not tell me but i will have it checked. Been told could be throttle position sensorl, speed sensor cracked case and a million other things. I have some mechanical abilities, (not too much w/ tranny's) but i can change a few simple sensors.

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?

My wife's 2004 v-6 has finally come to the point of harsh downshifting between 2nd and 1st,that she finally said something to me about it and that is unusual as she has the kids and music going so she hardly ever notices anything like that. I took it to the dealer at the 60k service and demonstrated the problem to them. Well, they did some software update 01210000 and it was supposed to be fixed. Well it isn't. and of course as before it does this intermittently so after they updated and drove it for a mile they considered it fixed. BUT it still does it.... It is a real harsh clunk/downshift just as you almost stop going from 2nd to 1st ? you feel it and hear it ....

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.
