Sonata NF (2006-10) :: Transmission Knock When Shifting Into 2nd Gear
Sep 26, 2013
I noticed that recently my 2007 Sonata (108k Miles) is making a knocking sound when it shifts into second gear. It happens only when I back out of my garage and drive down the street and the car is cold. After that there is no more noise, and the transmission is shifting through the gears smoothly.
I recently replaced the transmission fluid, about 5k miles ago and I used the recommended type.
I read other postings with people having the same problem, and in those cases they pointed to the ABS self-check which occurs when you first start out. But this is definitely not my case as the noise is coincidental with shifting into 2nd gear and it only does it when the transmission is cold.
Could this be caused by the fluid temperature or maybe because the fluid has not had a chance to circulate through the transmission and fill all the cavities? Its rather strange thought that I just noticed it in the last month or so, if that were the case I should have had this problem before.

I bought my sonata with about 48,XXX miles about 2 months ago, and now it has 52,500 (im a student - dont drive much). Anyways, whenever i start my car up and drive down the road, when the car shifts in to third, i hear a slight knock. almost like a little gong - metal on metal.
Once it does it the first time, it doesnt do it anymore. Im guessing temperature could have a factor?

This morning while driving on the freeway, the the transmission stopped shifting into 6th gear. This was at 70 mph. The only way it would shift up to 6th is by using the manual mode, however after manually shifting to 6th I moved the stick back over and it immediately downshifted to 5th at 70+ mph. Concerned, I pulled off and turned the engine off. After i restarted the engine, I continued to my destination and the trans shifted up to 6th on its own. The car has never done this.

As I was entering a highway onramp today, the transmission stuck and didn't shift between what I'm guessing was 3rd and 4th gear. It was revving at about 5000 RPM and stayed there.
After what felt like about 10 seconds, it got its act together and shifted and the revving stopped.

I around 1200 miles. The car would get going when i give it gas but it feels as if their was shifting lag or slipage. Only in first gear. Doesn't happen all the tho..usually happens on rolling stops... is this normal?

I just bought 07 Sonata CRDI tiptronic and it turns out it has problem when shifting from 2nd to 3rd gear: rpms jump up and i feel the kick.
It is not that noticeable when shifting at 50kmph, but worse when shifting at 60k kmph.
Same on Drive or when shifting manually. What the problem could be?

2007 Azera 120k miles. Have noticed first thing in the morning when shifting from 4th to 5th gear, I hear a clunk.. Yesterday I heard two clunks when downshifting from 5th to 4th. Tried shifting the car manually today and was able to replicate the problem. After 15 minutes of driving, the problem is gone.Never seems to happen in the afternoon after car has been driven.Transmission fluid is full. Have always changed at the 60k intervals.Fluid is not burnt. Light pink color.
What could possibly be causing this? Is this likely to get worse? How long might I have before the car might become not drivable ? I ask this because I have been considering trading it in for a new car. Now seems to be a good time to buy a 2016 car, since the 2017"s are almost out.

My friend told me the other day her car was in overdrive (hwy driving) and suddenly, it shifted to a lower gear. It seems no one knows why. She does have an extended warranty, but the garage might charge her $300 to open it up to see what is wrong. Another friend suggested a clogged filter. Another one, a sensor.

I have a 2006 GS RWD the transmission started acting weird 4 month ago went to many workshops and no codes were found in the computer and my problem is that when i am moving in the car for more than half an hour and stop the car seems hard and jerking while shifting to 2nd gear and if i put it in tiptronic it go to 5th gear immediately it seems ok when the transmission is cold so what do you think it has got 125000 miles on it and what is the normal temperature for the transmission so i can test it with mini vci...

I have a 2008 Accent (base model for the most part, no C/C), and my transmission seems to be slipping a bit. The symptoms are: slow acceleration, a delay in gear shifting, and after the 30MPH mark, it takes forever to get up to anything near 60. I just wanted to know if it's a simple solution such as topping off the transmission fluid, or if it's a bigger issue.

Just got my 06 3.3 GLS. Sometimes it seems to hang in between 1st and 2nd gear. No amount of throttle will make the car go or rev up until you let off and it changes gear. Then its fine. 79k miles, no cel. When i say it wont rev it will be at full throttle and engine and vehicle speed doesn't change. I just had the heater core replaced but not sure how this would relate to that issue? Someone said he thought maybe the trans needs to relearn its shift points after having the battery disconnected but not sure I buy that.

My trans is getting to fourth and then will go back to third and stay there, two codes, P0734 + 0735, which means the converter isn't locking up in 4&5th gears. And it physically feels that way. after clearing and cycling ignition I can get it to stay in fifth and use cruise control, as long as I stay above 40mph, below that it goes to third and then cruise control also stops working....

I recently had the transmission fluid changed in my 2009 Sonata NF 4 cyl. Current mileage is 60,000 miles. Directly afterwards, the transmission started "sliding" into 4th gear from 3rd gear. I assume that fluid contamination has caused a clog somewhere in the transmission. I have had the tsb done on the car for the transmission and the fluid had been exchanged @ 30,000 miles prior to this service.

Have a 2007 Sonata limited 3.3l, have trouble code P2507 and the car is stuck in limp home mode. Already changed input and output sensors on tranny. Battery is putting out 12V and alternator is putting out 14V when running. Cleaned PCM connections and packed with dielectric grease. Not sure where to look next.

I own a 06 sonata with 95000 miles. Recently I've been having issues with my transmission. It occurs only at slow speed when i travel in first gear. What happens is when the car is moving, it feels like it shifts into neutral but indicator still shows D in the cluster. I press the accelerator nothing happens it just revs,no increase in speed whatsoever.
So that rules out slipping issues. Now i narrowed the problem down a little more whenever the problem crops up i shift the gear lever into sports mode, i feel a jerk and car shifts into first gear and it moves. If i dont shift into sports mode it catches gear in about 7 seconds.No fault codes.
And if i rev it high transmission goes into limp mode and stays in 3rd gear till i restart the car.Then i get P0731 incorrect first ratio.Changed ATF 7000 miles ago. Could it be a faulty range sensor?

My 2006 Elantra (54,000 miles) shifts really, really hard when it's not cold and passes through the 35 mph range -- hard enough to make you glad you've got your seatbelt on. I've taken it to my regular mechanic and now it's in an automatic transmission shop.
My mechanic changed the fluid (twice), and took it through a "learning sequence". The fluid didn't look that bad and he reported that there were no codes to work with. He thinks I'm going to have to get a new transmission.
The AT shop has confirmed that there are no codes to work with and that the problem begins at 143 degrees. They tell me that the transmission is shifting into a higher gear without releasing the lower gear. They tried replacing a couple of solenoids, but that yielded no change in behavior. Now, they're telling me they "think" I need a new computer. I'm just afraid the trial & error approach is going to cost me a boat-load.

I have a 2000 F150 5.4L with 157k miles on it. I think it has the 4r70w trans. The transmission has started holding 2nd gear too long before shifting into third. Throttle position doesn't matter, it does it even under light throttle. I do not have a check engine light. I have owned the truck since new and the trans fluid has been changed 3 or 4 times. The fluid looks pretty good now, not burnt or anything. The truck has been sitting in the garage a lot over the past 2 years, I drive it at least once a month and have put maybe 2000 miles on it this year. It shifts fine through the other gears, just 2-3 has an issue. Truck has the towing package.

Replacing the knock sensor on a 2009-2010 Sonata with a 2.4l? Where exactly is it located and what has to be removed?

I went to Jiffy Lube and got an oil change, fuel system cleaning and cabin air filter replacement & sanitizing. I drive an '09 Sonata with 112K miles. When the car came out, I pulled away and noticed that the airbag symbol on my dashboard was lit and the center console was flashing that my passenger did not buckle their seat belt (I didn't have a passenger or anything on the seat). I went back in and after they looked at it, they said they couldn't find anything that could've happened at anytime and was a "horrible coincidence."
Hyundai ran a diagnostic tests and one of the 4 things that came back was B1389 (in addition to B1516, B1324 and B1515). B1389 signifies "Oil Temperature Sensor Circuit Failure." If the guy changing the oil damaged this (does this even get touched on an oil change), could that have offset the sensors for the airbags?
I just don't see how they done the above listed work and coincidentally my airbags are all deactivated afterwards. I'm reading a lot of bad reviews online, including quite a few for NOT putting oil back in the engine after the change.

Recently got quite a noticable clunk/knock from the front driver side of my '10 Sonata with the 2.4.
Only happens at low speeds, most notably in parking lots.
My best guess is a stabilizer link or a ball joint.
Took a video to explain the sound I am hearing.
