IS F (2008-2014) :: Tranny Will Not Downshift To 1st Gear When Stopping
Aug 25, 2015
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.

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.

So I was driving in a busy part of town today with a lot of stop and go traffic. Then this previous previous generation E class pulled up next to me and started reving it, his exhaust sounds aftermarket. I am the kind of guy that never race or drive fast on the streets, so I just ignore him. Then when it's green he pulled ahead and maintain at 30 mph or so, when I caught up he started reving again. He had his emblems shaved so I cant tell which model it was
So I was like what the hell...if he is a E350 or E500 he stands no chance, and if he is a E55 AMG the worse case it will be a close match. Different story if he is a E63, but it didnt sound like one. Since I was cruising in AUTO before, I must be at 5th or 6th. So I went into Manual, press the sport button and start downshifting......it took forever.....I was literally just waiting for it to go to 2nd before slamming on the gas...since the street in front of us is running out of room and will reach another red soon. Before I could get to 2nd, he already took off after cruising with me for a bit. When I finally got to 2nd and the engine growl started, I flew past him and let him hear the borla but we already hit the red...he turned right. I just thought I missed the fun.....
It was a hot day in LA...so the engine oil is well warmed up. And since we have so many gears, I often times find downshift sluggish and esp it cant skip gears..it has to go in sequentially. I have little to complain about the upshifts, but downshift..am I missing something here? How to speed up the downshift?I think dual clutch is way faster in both up and down....

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.

Just left my lexus dealer after getting an oil change. When I go WOT with the car in auto mode (whether or not in sport mode), it is very sluggish to downshift and when it finally does downshift, will accelerate very slowly above 4,000 rpm...almost no power.
In manual mode, no issue, accelerates great. All fluids are fine and no CEL. Gonna take it back to dealer in a few minutes.. Dealer has no clue what would cause the issue, they did not reset the ECU or do anything other than change oil and filter.

I was driving home from Las Vegas and my avalon just randomly slipped out of gear. I pulled over and put in into park and back into drive and it started to roll backwards the fluid is full and clean.... I bought this car 6 months ago and it barely hit 90xxx miles...

I have a 91 735i, 4sp auto, 3.5lt. Usually around constant speed of 40-45 the tranny will downshift then up then downshift an sometimes it will downshift to 2nd which scares me thinking it might downshift to 1st an explode the engine or tranny. If I engage cruise control it does not downshift. This does not happen all the time but when it does it can be very severe with jerking and slamming into an out of gear. The trans has a dipstick and the fluid does not look bad. I replaced head gasket and it was doing great for about a month and then poof the downshifting started.

So my 4motion downshifts going downhill while braking...it's annoying as hell! My DSG used to do the same thing but being a faster tranny it was actually NOT annoying... Is there a way to reflash the tranny software? Maybe with an older code because my 06 didn't do this but my 08 does...

I just got my ISF 3 weeks ago and this issue got me pretty worried. I would like to hear if there has been a recall or a fix on this issue. While in Drive (D), the tranny wouldn't shift past 2nd for a couple of seconds. It went as high as 4.5RMP and wouldn't shift, the RPM kept going up. Letting go off the gas did not work, the RMP just stood where it was and slowly decreased with the speed. This lasted for a few seconds. I must admit that I was just pulling out of the driveway and she wasn't properly warmed up (16 degrees temp or 60fh)...

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 just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.
We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.
I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?

I need to solve tranny problem, it started out a while back, would not shift back into drive after stopping at stop sign (after driving fine for about 20 miles) thought maybe dirty filter so did fluid and filter change seemed to work for a while then started again noticed it was mostly after using cruise control, but u joints were very bad, so replaced 2 of the 3 and worked fine for about a thousand highway miles, then got really bad. Now when I check the tranny fluid cold and /or hot it is way up on the dipstick. Took to ford dealer in ladoga, lied and said no speed sensor codes, but list on the paper he gave me had all kinds of abs and a p500 code.

Ok, so in M mode shifts can be a little rough from 2nd to 3rd unless I give it enough gas. It's no big deal and my car has always been like that (owned it since 9/2013). But as of yesterday, shifts have completely changed from 1st to 2nd. It is clunky, extremely quick and lurches forward every time in M mode. It has NEVER done this before and it kinda sucks.
I've read all of the threads regarding tranny fluid, belt squeak, etc. and haven't specifically found anything like this. I haven't done anything to the car except the ELF recall and an oil change about a month ago.

Starting here to ask first but I currently have the CEL and VSC light both lit and 1st gear is locked out. What is causing this without having the codes read yet? Is it common to get both of these lights simultaneously? Having 1st gear locked out seems very concerning from a mechanical aspect to me, should I have it parked till I get it serviced?

I've never had this happen before, but today on my way to work during my first and second stop I noticed the car have a jerk when coming to the stop. I immediately thought it felt like the transmission was acting funny so I switched to the gear position view on the dash while at a stop light and noticed the car had placed itself into 2nd gear at a dead stop.
Some background info:
1) I only let the car heat up for 45 seconds max before driving.
2) The indicator light is just my TPMS or whatnot because I have Winter tires.
3) I have the common harsh shift when cold 1-2-3 until its driven for a few minutes.
4) It was -4 Celsius
5) I am in Normal Mode and never ever drive the car hard until it hits 2 bars on oil temp and then almost never drive it fast (why did I even buy an ISF?)
6) The car recently had its service done at Lexus (I denied the rear differential fluid change as I am getting this done at an independent garage.)All other services have been properly maintained since new.
7) The car returned to starting in 1st gear at stop after it warmed up. I am just curious to hear if this is normal or an indicator of a potentially larger issue down the road.
Also off topic but in my old IS350 in winter mode it stated the car in 2nd gear in snow mode. On the ISF snow mode still starts the car in 1st gear (online seems to show it start in 2nd? i.e. top gear etc quotes it does this.)

I have a 2008 ISF at 41k miles. In stop and go traffic, or starting from a stop and driving causally ( not WOT or even medium throttle) the car will rev up before going into 2nd. It is like the feeling of rolling over a speed bump.
Also in normal or sport mode in D ( not M ) if I WOT , you can feel it jerk before taking off. I don't know if this is normal or not...

My 2011 ISF has around 50K miles. Recently I noticed that when I shift into 1st from 2nd, usually on approach to a slower curve or slowing down to a light, there appears to be a distinct shudder. It doesn't happen all the time, and it happens regardless of Sport or normal mode.
Right after it shifts to 1st and the RPMs climb (or so it seems), I get 3-4 distinct back and forth movements .. i.e shudder. I think this is a recent phenomenon, as I know shifting into 1st is usually not very smooth, but I don't think I felt this shudder before.
No codes etc ...everything else normal. Don't think the trans is slipping, as car pulls hard and traction control is always busy. Motor mounts? Car is never tracked and driven spiritedly, but never ever abused or tracked. I do enjoy shifting it.

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.

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.
