I took my Phaeton in for a transmission noise and they are saying it's "normal" for V8 Touaregs and Phaetons to have this noise on downshifting under acceleration from 4th to third at around 40 MPH. Yes?
View 2 RepliesVW replaced my entire transmission and it still jerks into gear when downshifting to a stop or hitting the gas hard while coasting!
Also, I swear there is now binding while turning a la moteur stepper. New tranny. New rear drive shaft. Allegedly new transfer case (I cannot confirm this though). New new new programming. And still the darned thing vibrates by butt with a downshift that a Bettle with 300,000 miles on the clock would not dare make.
Any reference to the operation of the transmission and the sequencing of the various clutches and other coupling devices with respect to gear selection and engine conditions?
Ok long story short I was given a conversion van that is built on a e150 van and has a 5.8 liter with an e40d tranny.. This van sat for at least 3 years till recently..
I have cleaned all electric connections on the tranny and the one on the rear differential . New filter and fluid but did not drain the converter after driving it for about an hour we finally got it to start shifting gears automatically the problem is it wants to shift only under heavy acceleration and then only to second at about 35 mph and drive at about 60 mph and over drive around 80 mph and all this only under heavy acceleration you let of the gas a little and it starts down shifting..
What I may look for next that may be pretty easy to try. My thoughts at this point are maybe the torque converter is going south but I am hoping for a more simple solution..
The Touareg is my wifes vehicle, so I do not drive it all the time, but I do all of the driving on our vacation. Let me start by saying it was quite hot and humid on vacation so this may be part of the cause. Like the topic says when parking and or turning from stop or at low speeds there was a very noticable groan/hum coming from the front of our 2009 V6 Touareg. Is this common/anything to worry about? Before vacation we had just had it in for the 10k service and everything checked out ok.
View 9 RepliesI've got a V8 with about 250 miles - I took delivery last Saturday. I'm hearing a groan in the exhaust between 1000 and 1500 rpm.
It sounds (and feels) like it's coming from the underbody beneath the center console/arm rest. I can feel the vibration in the gas/brake pedals and the driver's seat. It doesn't seem to matter what speed or gear I'm in... even Neutral. Definitely related to engine rpms as it happens while downshifting as well.
I haven't looked under a T-reg lately. What is under that area... is there a resonator in the exhaust? It almost sounds like a loose brush shield or maybe a bad baffle somewhere.
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 RepliesEnjoying taking trex out in the snow here in the northeast this afternoon... When I accelerate, I hear a groan coming from the front axle and the ESP light blinks on/off.. Is it normal? Still happens if i turn ESP off...doesn't happen in my wife's glx passat (4motion), so it seems unusual to me...
View 5 RepliesI have been having this problem for the better part of a year, about 80% of the time when my transmission tries to downshift from 5th to 4th gear I hear a loud thud/bang which shakes the vehicle. The other 20% of the time the donwshift is smooth. I have tried manually shifting and get the same result. The problem does not seem to be getting worse. I have adjusted my driving and when accelerating in 5th gear at moderate speeds I accelerate just enough to keep tranny in 5th, so I don't get the thud.
View 4 RepliesI don't know if this will be corrected by the next Tranny Flash (since the current flash wasn't applicable for my 61xxx VIN and engine code), but I have noticed that whenever I opt for Tiptronic, and downshift, my Treg seems to speed up first. I don't notice any significant engine braking until I apply the brake.
View 16 RepliesWhen my TREG is downshifting from 3rd to 2nd gear, it sometimes blips the throttle just a bit before settling into 2nd. Almost like one would do when down shifting a manual transmission.
View 3 RepliesI have a '05 V8 T-Reg (loaded with Air, NAV, and the like) and have the local VW dealership perplexed. The problem is when I am going up a hill and slowing down. While downshifting the T-Reg lunges forward while moving from 4th to 3rd gear or 3rd to 2nd. The car jumps forward and the engine revs. If I don't have my foot on the brake I would smack into the person in front of me.
Initially, the dealership (Day Imports, Monroeville, PA) determined it was the valve stems and replaced them (after keeping the car for 4 days). The problem came back and now (going on 6 days in the shop) they cannot find a solution. They tried a new shifter plate but the problem still exists. I'm waiting to hear back from the service manager about what VWoA should try next.
The T-Reg has 72k miles on it...
Having downshifting problems with REbuilt transmission. Is there a FIPL sensor for the 4r100? I was told to check all engine codes first, but i just have a EBPV sensor code, but removed the valve when I installed the GT38R turbo...
Rebuild:
- Tugger kit
- triple disc Billet torque converter
- New clutches and seals,.
- Banks Trans command module
... I also have a 6-pos tuner.. I had a Super chips tuner too and it has ALWAYS had the downshifting on acceleration on up-hill grades!!
When approaching a red light, if I take my foot off the gas to coast, it feels as if the transmission 'downshifts' at around 30mph. I can't actually feel the transmission shifting but there is a definite slowdown in speed, not just a gradual slowdown. Is this normal? I ask as doing the same in the '04 RX it does not do this.
View 5 RepliesI've been driving my wife's sonata to work this week and notice as I start to slow down at around 20MPH the car almost surges a little bit. Maybe I am not diagnosing it correctly but it's almost like it's downshifting rough.
View 37 RepliesWhen coming to a quick stop the transmission has a shutter upon downshifting the shutters when you accelerate quick off of a stop light or stop sign. Also quick left hand turn hear a clunk coming from left side wheel. 2015 Sonata Sport 2.4L
View 7 RepliesWhen I am going about 55 my transmission sometimes starts downshifting and then up shifting again for no reason.
View 14 RepliesMy freshly rebuilt C6 with Transgo shift kit and Hughes 2500 stall converter won't downshift until I'm nearly at a dead stop. My Cruisomatic did the same thing in stock form. I roll up to an intersection and the light is green. I slow way down to negotiate the turn. I then throttle when headed straight and the tranny is still in Drive. It does the same thing when slowing way down for speed bumps. Could the shift kit or stall converter affect downshifts?
View 10 RepliesUpshifting is fine, downshifting gives me a big thud. Bigger from 3rd-2nd smaller 2nd-1st (I think).
2006 GS430. 120k or so miles.
Dealership replaced solenoid #2, but now say I need a whole new transmission.
Heard a clunk and then have the car feel like something from the inside is trying to stop it when using the paddle shifters in manual mode. Specifically when downshifting from 2 to 1. By the way I did a slight throttle blip, I have done this before with very smooth results but this time it really scared me, I though the transmission broke for a second; when the car did what it did.
View 6 RepliesHave an unfortunate circumstance. '03 Camry XLE 4cyl with 188k on it and the trans just went crazy. Was on the interstate and it started downshifting. Wouldn't stay up in the gear it was before and eventually wouldn't go out of 1st or 2nd gear.
Haven't had shifting issues in the past and trans fluid has been changed regularly at no more than 30k mile intervals.
Worst part is that this was on the way to vacation, so the car was towed to Ft. Walton Toyota. They are saying the trans is slipping and it needs a rebuild. Seems very odd to me that the issue would come on this fast with no earlier signs. A valve cover gasket was replaced a couple weeks ago, but I don't see how that could be the cause.
I have a 2009 that seems to have issues in the lower gears, I think that I have a transmission issue.
When I'm coming to a stop, I feel the transmission downshifting from about gear 3. It's not wildly jerky or abrasive, but it's not smooth either (or I wouldn't feel it). When it downshifts, after it engages (or torques down for lack of a better term) it feels as if it releases a bit, which makes me have to compensate with harder braking (again, not saying I am slamming on the brakes, but I have to brake harder so it doesn't feel like I am now going to coast into the car in front of me). It doesn't feel like the transmission is going to take off on its own, but it definitely feels like it has a certain threshold it wants to stay above.
In the loaner I have (RX), when coming to a stop the best way I can describe it is it feels like the transmission has completely disengaged and I feel NO transmission downshifting at all. The only way I get this type of braking in my LS is if I throw it into Neutral and take the transmission out of the loop. On the way to the dealership this morning to drop it off for other issues, I was at a stop light and went to accelerate and it felt as if it skipped a gear because I was stalled for a second (acceleration wise, not that the engine turned off) before it took off as it should. Also my acceleration seems to be a little hesitant when starting off .
