#13 of 362 2003 Hyundai Sonata Transmission Whine
Oct 31, 2007 (7:56 am)
I just moved to Denver - after about a month (one week after a cold freeze) I noticed a slight whine when the transmission is in third (approx 2300 rpm) between 38 and 42 mph. It seems to disappear immediately on shifting to 4th. I do not hear it when the transmission downshifts. I might also mention that I lived in San Diego, and, at 30000 miles had the transmission fluid changed as part of the 30000 mile checkup. I do not believe they used Hyundai fluid. This was a AAA aproved repair shop and they provided documentation that said that the transmission fluid they used was OK for the vehicle.

For whatever the reason Hyundai automatics require specific Hyundai branded transmission fluid. I do not believe any other generic type is recommended. As far as I know there is no other type or brand that should be used. Also,I seem to recall this wasn't a Hyundai ruse in order to force owners to buy their transmission fluid only but this requirement had roots in actual performance problems if it wasn't used.

The transmission fluid that was used was Valvolline Max
Life ATF which is supposed to be consistent with SP-III. I have a signed letter from Valvoline which states that use of the fluid WILL NOT INVALIDATE the Warranty and it also lists all the vehicles that it is recommended for - which includes KIA SP-II and SP-III and Hyundai. Although I voiced some concern about this - I was assured by a reputable AAA repair shop (SAMCO in San Diego) that I was OK to use the Valvoline transmission fluid.
#16 of 362 2008 Sonata transmission shutter
Dec 28, 2007 (11:08 am)
I just bought an '08 Sonata in November, 2007. Right away I noticed a definate shutter when driving around 40mph, just prior to shifting to 4th. It will remain as long as I stay at that speed. I took it in to be checked twice. 1st time tech didn't find it, 2nd time there was a TSB, and the transmission was reprogrammed. THAT was yesterday. On the way home, sure enough, it did it again, and again. Any suggestions? Thanks!

This has been noted by a few with no fix so far.

I recently purchased a the 08 Sonata, my very first car. Within 200 miles I noticed the shutter at or around 40 mph. I have taken the vehicle to the dealer more than three times,and have finally been assigned a "case number" with the manufacture. I do not like, and refuse to accept this malfunction.... Does anyone have any suggestions or advice on what I can do?? I have been advised that there is no solution and this is a known issue with this vehicle.

Well i have been struggled with this problem on my car (V6, from korean) from day one since i bought it in july 2005.
Another with the same problem:
All (5 or 6) similar models i have tried here in denmark had the exact same problem, and the danish importers technical manager, who also drives a V6 has the same problem, and finally accepted that there is problem that apparently cant be resolved. And i must say that, as far as i know, all have been tried from here.
An A/T specialist even tried to deactivate the torque converter lockup by bypassing the brake-switch, but it didnt bring us closer to a solution (same shudder or even worse).
Status for now when my cars has approx 52000 km on the odo:
Get the tires optimally dynamically balanced (Hunter), and the vibration can be minimized (I have at least experienced that high tyre RFV (Radial force variation) and out-of-round can intesify the problem)
The more perfect tire - the less wobble/shudder/vibration
- But even with the most perfect tyre, as the set i have now where the RFV on all four tyre is below 2 kg, i still got a slight vibration. (Michelin PA3 winther)
The point now is, that if i not have had all these problems from the start, and really got attention to it, then i guess i wouldnt have noticed it today. With my last set of tyres it's hardly noticable.
I just hope that all my complains in the last 2½ year has been noticed by Hyundai and hopefylly has been resolved in the facelift...
I'm really looking forward to try it when it arrives to Denmark in the 2. quarter of 2008.
If it is solved - i will definately change...
In all other areas - i think the car is perfect, and i wont hesitate to buy one again.

check for the "lemon law" in your area - if it is allowed RETURN THE CAR AND REQUEST A NEW ONE

I have a Hyundai Sonata 2008 2.4l 2,700 miles, Automatic. It has a slow shift between 1st & 2nd gear
Feels like a loss of power until it passes 2nd gear, fuel mileage is 19-21 city/hwy 60/40 hwy. Took it to the dealer and no codes in the computer. Any answers will be helpful! Thanks!

Although this addresses old posts - let's please put the question on ATF for use in Hyundai's, Kia's, and Mitsubishi's to rest once and for all. These three corporations require SP-III ATF, not SP-III approved, or SP-III equivalent fluids. There is no direct substitute or equivalent SP-III on the market. Regardless what Valvoline, or any other companies claim, unless you use Hyundai, Kia, or Mitsubishi brand SP-III ATF in your automatic transmission, your warranty is null and void on any transmission failures. This is direct from Hyundai corporate. The Hyundai and Kia automatic transmissions are built under license from Mitsubishi, and again, if you use anything other than SP-III, you're out-of-luck on substantiating any warranty claims should an automatic transmission problem develop within the 100K/10 year powertrain warranty period.
Don't try to save a few dollars per quart on ATF, just buy the real stuff!
