Phaeton :: Rough Shifting In Sport Transmission Mode
Jan 29, 2008
I'm having a ton of fun driving in Sport transmission mode. One thing I'm noticing though is pretty rough downshifting from 3-2-1 sometimes. Often I hear and feel a clunk.
So I'm wondering if the transmission may not be adapted to me yet, since I've only had the car for 5 weeks, or could I be looking at an issue. No lights or warnings on the dash.
Also wondering if there is a way to "reset" the learning algorithm of the transmission without the VAGCOM?

When driving in Sport Mode I have a violent down shift as the car slows and heads into second gear from third. It doesn't seem to matter if I am going 40 miles an hour around town or 70 miles an hour coming off the freeway. There has been a few times where the jerk is so hard that seatbelt tensioner tightens. Is this a normal aggressive function of the sport setting, or is this something else? Perhaps related to the transmission valve/hard second gear shift issue?

Lately I have been driving in the Sport Mode more often. I have noticed that when accelerating from a stop it revs to just below the redline before shifitng, is this normal?
I also notice that when slowing down or coming to a stop, it has a "hurky jurky" feel. As if it was downshifiting way to early. is this normal?

I've always wondered why the transmission automatically shirts to 4th gear when I switch to sport mode! Is this normal??? It's an i4

anyway to set it up so it always starts in S or S+ mode so I don't have to always remember to do it.

It's just the throttle response? Is steering or brakes enhanced or is it just me? I know the Is250 didn't get the suspension option like the IS350.

I have a 2012 elantra manual transmission. I noticed the eco mode but never found out if it really does anything. when I shift from 1st to 2nd at higher RPMs its rough. At other gears its ok but I feel like the gas pedal is weak sometimes. With a manual does the eco mode make that more difficult?

So i noticed, when in auto mode, whether sport mode is on or off, it does the same thing. If i floor it from a stand still, the transmission takes noticeably longer to go from 1st into 2nd then from 2nd to 3rd, 3rd to 4th, etc. 1st to 2nd takes like a good second, kinda like this:
1st VROOOOM.....................2nd VROOOM..3rd VROOOM..4th.....etc..
If I drive it in manual mode, then it shifts just as fast. So this only happens in auto.

While driving in either D or S mode, the transmission jerks in 3rd gear changing into 4th and then its fine. but it always happens in 3rd. The jerks are very very quick.
My car is 4.2L 2004 V8 (6 speed) and it has 30,000 miles on it.

My transmission control module has gone bad, resulting in the car being in"limp" mode. I am advised not to drive the car in this condition as it starts out in 3rd and the transmission will be damaged. Thus far, my local dealer has, on a preliminary basis, been advised that there are none of these parts available anywhere in the world according to the computer and VW may have to manufacture one. This does not sound possible. Meanwhile, the dealer says no rental car will be offered so I am contacting VW North America to escalate. It could be up to a month to get a new part. Meanwhile, the car is in the garage just sitting.

I was driving at 40 -30 mph on a dark street and rammed through a bit of water ( maybe 4" high and 6 feet across). So right after i got these tranny codes and my tranny went to safe mode kicking hard when shifting:
P0705
Transmission Range Sensor Out Of Self Test Range Or Shorted To Ground
P1783
Transmission Over Temperature Condition
P0712
Transmission Fluid Temperature Sensor Circuit Input Low
P1702
Transmission Concern
Luckily I was a block away from home. So i assumed all those sensors shorted with water ( I thought they were all water proof...hmm) so i let them dry.
So the codes went away and the truck seamed fine for 2 weeks until i felt the tranny kicking again into gears yesterday. So today i went on a test drive and it was fine at first until it went into safe mode again with only 2 codes:
P0705
Transmission Range Sensor Out Of Self Test Range Or Shorted To Ground
P1702
Transmission Concern
So, that means the other sensors dried out and i destroyed the TRS? and if so would it malfunctioning cause the tranny to go into safe mode or could there be some other issue?

I have a 2005 2.7L Santa Fe that was shifting poorly and getting stuck in limp mode intermittently. I read up on it and found that it was probably an issue with the input/output speed sensors. The codes confirmed my suspicions and I replaced both the input and output sensors. The codes cleared and the tranny shifted like a dream. Unfortunately after 2 days and 100+ miles the car suddenly started down shifting randomly on my way home from work. The CEL came back on and the car went into limp mode. Could the sensor have gone bad again? Or could it be the wiring harness that plugs into one of the sensors? I don't understand why the car would be fine for a few days and then all of a sudden be acting the same way.

I have a 2006 f-250 super duty with a 6.0 and auto trans. I was pulling a trailer with about 5k of vehicle on the trailer.
Problem : after a long trip on good roads, I had to pull a steep hill. climbing the hill i did not shift into tow mode and all of a sudden my engine raced up to about 3k rpms and seemed to either shift to low or ( maybe ?) the Governor may engaged ?
Anyway I made it to the top of the grade and it seemed to be fine from there.
Question Is the trans broken, or did the computer maybe try to protect the trans ? It seems to work fine still?

Just this morning I noticed that the first shift my automatic transmission makes is not so smooth. Almost like I'm getting a slight shove from behind. Repeated at every stoplight. I know I'll be calling the dealer tomorrow, but am hoping to get ahead of the curve and be prepared for what it might entail.

I have an automatic 2010 Elantra Touring and I drive 115 miles a day (4 days a week) with it (currently have 38K miles). Part of the drive goes up over an 1100 foot foothill, so I change elevation of about 800 feet on the drive. Over the last two weeks, I have noticed the transmission shifting a little rougher and at higher RPMs (everywhere and not just going up the hill). The transmission fluid level looks good, but I am wondering if I need to change the fluid and filter? Or is there something else I need to look at? I need this car to last another three years and want to make sure I take care of it right. Currently every 3500 miles I change the oil and rotate the tires, but I am just not sure about the transmission.

I just bought a 2013 Barcelona Red Corolla S in Manual transmission. Already, I've noticed how rough the transmission is when I shift. But it's only roughy when I first step on the clutch. But if I keep the clutch pedal down, all the gears shift smoothly, until I release the clutch and press it down again, then the first shift is really rough. Especially REVERSE, when I shift into reverse, it's so rough that it shakes the car. There's no grind, just very rough. It sounds like someone cocked a shotgun. Everything is smooth when driving tho, only happens at full stop.

Every so often while driving in the city my car starts shifting rough between 1st-2en and 2en-3rd gears. If I stop; turn off the engine and then restart it stops. The car has 107,000 mi. and the fluid has always been changed as recomended. Do I have a shift selonoid going out somewhere?

I have a 2007 Passat wagon 4 motion V6 and what the problem is I am getting a rough shift between 3-4 gear sometimes, usually on a slow acceleration. I have had the valve body replaced which worked for a couple of months until the problem returned. I then had the transmission replaced which worked a little but the rough shifting is still present at times. The car still has warranty and not even the dealership knows what to do?

Recently changed the transmission fluid in my 2011 Elantra. Used the fill plug to check fluid. Small steady stream was coming out. Closed it up and took it for a ride. Was shifting very rough. Put more in and it felt better. Was wondering if there is a better way to check the fluid? I've heard that the dealer may have a sensor, is this true?
