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 RepliesMy 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.
This is what is happening:
1. When you start driving the car it accelerates fine until it gets to second gear where it keeps accelerating, then you feel a jolt, the odometer jumps 1-2 notches, and it switches into third.
2. When stopping it downshifts fine until second gear getting ready to switch into first to come to a complete stop and again it "jolts"
3. (Sometimes happens) When driving ~25 mph or ~40 mph while continuously accelerating you let-off the gas and then reapply, it stops accelerating and kind of "sputters" and can not accelerate anymore, I have to stop put it in Park and then again put it in Drive and only after that it works fine.
I have taken it to the VW Service and the mechanic could not replicate what I said was happening so I drove with him in the car and replicated the first two steps 3 out of 6 times. He told me that they checked the codes and could not find anything malfunctioning. I told him that clearly something was wrong with the transmission and I wanted something to be done. He agreed that he also felt what I was talking about but it was not enough to come to a conclusion to what was wrong. I mentioned that I wanted this to be written down in the service report, because if something happens they will be aware.
The problem now is that the "jolting" and the stalling-out has gotten worse since the visit to the service 1 month ago. What might be happening and what I need them to repair/change on my car. I am planning on making a visit sometime this week. The first two steps happen when the car is cold or when I switch over form Tip-Tronic to automatic. But that is not always the case.
Took my car to the dealer for it's 80K service and asked them to check the tranny because it's been slipping (hesitation) during upshift and occasionally banging into gear during downshift. I figured they would suggest the BG tranny fluid flush but got a call from the service advisor saying they found the fluid to smell burnt and it was black. 1999Pazzat V6...
View 8 RepliesI've been driving manual 12 years, all my driving life, and been in 10+ manual vehicles during that time, including a 10+ year stint in a 1.8T Passat with a 5-speed.
In all that time, and all those experiences, I've never replaced a clutch, damaged a clutch, or had one problem. In fact, I consider myself a very good operator of the manual transmission.
This is preface to my current situation. 2009 Tiguan (early build) 2.0T 6M, driving at 57mph in 6th gear - downshift to 4th to pass a truck and WHAM. Grinding, confusion, and then the clutch pedal stuck straight to the floor. Glide to a stop on the side of the bayou road.
Totally immobile vehicle. Impossible to shift into gear, or get the pedal off the floor except by pulling. Smell of acrid smoke.
VW dealership says "we're doing a courtesy warranty repair" on the clutch, flywheel and bearings, as if it's my fault. Impossible. This is a mechanical defect if I ever saw one.
02 Montana with 4T65E electronic 4 speed transmission. car has 75000 miles. normal driving and shifting seems to be fine. Transaxle will not downshift with accelerator pedal pressed to the floor. no check or service engine lights.
View 1 RepliesRecently my F350 has failed to downshift when the accelerator pedal is pressed to the floor to speed up in traffic. It will usually happen when traveling at speeds in the 30's-40's. It will shift quickly at slower speeds. I have a scan guage on it all the time and it is not throwing any codes.
The transmission has only been serviced by the dealer; last done about 24000 miles ago. No leaks or low fluids/no burned smells. Stock setup with no heavy towing use. Currently at 228000+ miles, this is the first issue with the transmission assuming I am looking at the right area for the cause.

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?

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.
View 3 RepliesI have a problem with a bmw 1996 7 series transmission.When I start driving the car all gears shift fine, but when I come to a stop it won't downshift to first gear,i have to put the car in park and then in drive again and it run ok until I come to a stop again.
View 4 RepliesMy 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 ....
View 3 RepliesSix speed GTI Manual for those that dont know its a 2.0 TSI. Fifth gear grinds all day long when i downshift or upshift. They have given me a service car to drive around in, until its fixed. 25k on the OD and a 5 year mechanical warranty, i have 2 years left on the rest. Third gear doesn't go in easily, its like i miss third gear all the damn time, obviously its not right when the rpm's go above 3k.
View 18 RepliesHave an 01 vw beetle stuck in third unless I manually downshift it but still wont shift into overdrive.
View 2 RepliesHappened today during the snow storm. I never drive in auto when it's snowing. I usually use the first 3 gears to get around, this allows me to engine brake, which reduces the slipping and sliding greatly.
Anyways, today my car ( after 3 winters and many snow events ) decided to disable the 1st gear ??? I have tried turning the snow mode on / off as well as the VSC , but the car would not give me the 1st gear back
Eventually it released it and I was a happy camper again. Below is the message I was getting every time I tried to down shift.
Very strange issue today. While driving in stop and go traffic (Auto Sport Mode). I noticed the car was starting in 2nd gear. Next stop I switched over to M and it would still not downshift to 1st even with the paddles or shifter. Once I started moving I could manually downshift just fine. Car seemed to shift normal. Eventually got the VSC / CEL . Here are the codes:
Pending:
PO301 - CYL 1 Misfire
C3101 - no details
C3411 - no details
C3000 - no details
Historical:
P0A11 - DC/DC Converter Enable circuit open
All of the codes cleared and did not reappear while idling. I have not driven the car yet. It also goes back into 1st now while stopped although I haven't tested coming to a stop. Will do that tomorrow
One thing to note that was out of the ordinary today. For some reason I was absolutely freezing (which should be impossible this time of year in SC) so I turned the AC off before this started and the idle dropped very low (400 - 500) which I seem to remember being normal but I almost never run with my AC compressor off unless I'm in race mode and I'm usually not putting along in stop and go traffic if that is the case. Not sure if this has anything to do with it but perhaps the low idle caused a voltage issue which tripped the codes.
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.
View 11 RepliesMy 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.
Ive got a 2006 5.4, Fx4, screw, with 90,000 miles.
Recently it shifts perfect except when it down shifts from 4th gear to 3rd gear. If i mash the pedal it is fine, its only when it just a slight acceleration and it is a easy down shift that causes the problem. What it does is almost like it wont lock into the gear, it bucks lightly but where I can feel it still. Im going 40 to 60 mph when this happens most of the time.
I am not sure if there is a sensor of something else that would be the cause this of is maybe my Transmission is just shooting craps. Also, i have a SCT tuner that i havent hooked up to the truck yet, but do you think if i plugged it in and turned up the shift firmness if it would work.
On my 2012 Avalon, moving shifter to the left of "D" for manual mode causes a downshift to 4th gear. Is it supposed to do this? For me, this would be poor design in that I may be setting up to pass, but not quite ready to downshift to 5th yet. And even going 60mph it still gets 4th... Or I may be going to climb a mountain (as I was going to Colorado last week) and only need 5th, not 4th. So I have to upshift to 5th AFTER I move to manual mode..
View 7 RepliesI have a 2001 Accent with a 1.6. This car is mostly driven by my daughter so I'm translating the symptoms as she has described them to me. The issue appears to be this - when driving at highway speeds the car will sometimes downshift from OD to 3rd gear and stay there. When the problem first started, she would pull off the highway, turn off the car and then restart it - this would appear to "fix" things temporarily, however, as time went on, it would work up to (and including) 3rd gear and not go into OD after a restart.
I've reviewed the various threads on this site describing the 4th gear problem prevalent in the Accent, but in each case that was posted, there was a check-engine-light or at least some diagnostic codes stored that one could refer to - I've scanned this car every time she's been home and there are no DTC's. Should I assume that this is the standard "4th gear" issue and take the pan off for investigation or could this be some other issue such as the speed sensor causing the transmission to limit itself to a max of 3rd gear?
I searched a lot but did not find these symptoms on my 1992 Aerostar 3.0 2WD with A4LD transmission.
In overdrive, accelerate to down shift, and the transmission goes out of gear. Engine revs as if it was taken out of gear. Manually shift to Drive, and it works fine.
Overdrive works fine if at speed, and works to shift up, but if going slow enough to drop to lower gear, transmission goes out of gear. Manually in drive, works fine.
I may have other symptoms, but this was on the way home from work, and I just parked it. I checked fluid level, and it was fine, still in the cross-hatch area of the stick, light colored oil, no smell.
I will replace the modulator and replace the filter, and see what that will do. If the overdrive works at overdrive speed, I do not see how that could be an overdrive housing failure that I have seen in many posts. I am aware of keeping track of the pin for the modulator.
I also have read that band adjustment is not a good idea. If they are worn that bad, they should be replaced. I don't think it is a band or clutch problem. I think it is a shift control problem. We will start with the modulator and filter and take it from there.
