Replying to: toshas (Jan 04, 2008 8:58 pm) http://www.hyundai-forums.com/index.php?showtopic=6559 Another with the same problem: http://www.hyundai-forums.com/index.php?showtopic=19223 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. |

Replying to: craigbrooks (Dec 30, 2007 10:01 am)  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! |

No one has changed the transmission fluid in this car, it still has the factory fluid.

Replying to: colloquor (Jan 15, 2008 5:48 pm) Your Hyundai automatic transaxle is specially designed to operate with HYUNDAI GENUINE ATF SP III, DIAMOND ATF SP III, SK ATF SP III or other brands meeting the SP III specification approved by Hyundai Motor Co.. Now how you interpet that is up to you. I read it as they are saying a fluid that meets the SP III specification that Hyundai approves for use in their transmissions, not that Hyundai has to specifically approve an aftermarket manufacturer. But since I only have 19,000 miles on my car and have 31,000 miles (approx 11 months for me) to go before I begin to think about doing a flush and fill I have time to wait and see what happens. I do sell Amsoil and they make a ATF that they say meets the SP III specification along with the Castrol product I saw on a store shelf this weekend and like has been said on here and other forums some people have changed out to other fluids and we will see how it goes for them. I am not having a problem currently with my transmission and hope not to but when I do change out my trans fluid I will base my decision off of a cost basis, i.e. Hyundai labled ATF, cause they do not make it do they, or one of the other ATF's out there. I can't believe Castrol, Amsoil, or any other manufacture would be selling a product that they say meets the SP III and it did not. The lawsuits would sink them rather quick and if you did use the Amsoil ATF and it ended up destroying your transmission and it was the fluid that caused the problem they would either pay for the repair or replacement of the transmission. I would think Castrol would also be required to do the same since they say SP III right on the bottle. |
