Your car only had 30,000 miles. MaxLife products are intended for higher mileage cars (75,000+ miles). In spite of the product sheet claiming compatibility with Hyundai specs, I wouldn't have allowed its use in my car. I'd buy some Hyundai-branded ATF and take it back to the Samco shop; they should be willing to swap it out for free.
BTW, how was the job done? Unless they used a pressure flush system, more than half of the ATF fluid does NOT get replaced. (I'm not a fan of the pressure flush systems, which attempt to flush the fluid out of the torque converter) So you have a 50%-50% mixture of old Hyundai fluid and new Valvoline fluid, which is pretty scary.

#52 of 339 2001 Sonata Shifting Problem / Check Engine Light
Aug 11, 2008 (7:33 am)
Bought my Sonata new in 2001, has had a couple of no charge factory recalls. Here in Florida batteries only last about 12-24 months until I went with the Sears Diehard Gold. It's been a great car for 7+ years, but now it's starting to shift funny. We were in Orlando (from Tampa) and as we made a U-Turn and I stepped on the gas the car revved high then the transmission made a car jarring clang/bang and the car started to move again. The "Check Engine (CE)" light came on so we went back to our hotel. All other functions seemed normal, so I let it set overnight. The next day the car seemed to be fine still, and the "CE" light went out.
Everything was fine on Saturday and Sunday until we left Universal to head back to Tampa, and the "CE" light came on again and the car seemed not to be shifting properly especially taking off from a stop & at highway speeds to top gear didn't seem to kick-in.
I've done some research and I know the "Shift-Tronic" type transmission is supposed to self-adjust to the way the car is driven and I don't always drive it smoothly. I remember the dealer service dept. telling once when I had my car in for regular service, that they were having trouble updating the CPU software and I don't think they ever got it reinstalled correctly (of course they'll never admit it).
I also put and OBD2 box on it myself at one point and the code came up as "unknown", I put the OBD2 box on my spouses Honda CR-V and it worked fine, so I'm fairly sure the OBD2 was ok.
My local dealer service dept is a bunch of jerk weeds so I've been having my car serviced by a local service garage whom I trust, but I'm going to try the dealer today for this problem. So we'll see...

I have experenced the same problem, I to have a 2008 Sonata with 2858 miles and the dealer's service tech said he couldn't hear the noise. My question is do you still have that same noise or has it been resolved ?

Actually, it's not fixed. I spent $300 to replace the Input & Output Speed Sensors per the dealer service tech and their so-called diagnostics. My Sonata's engine was purring like a kitten when I took it in (it was only the transmission that was shifting funny), but since I picked it up the car has been running very poorly and the once quiet engine has been making a lot of noise and yesterday it started shift funny again. Clearly they didn't fix anything so I'm calling them again today and we'll see what kind of BS they'll feed me this time.
As for your 2008 Sonata, lucky for you your's is under warranty. As stated previously, the Sonata is a well build car and I will definitely buy another one. However, the dealer service techs and their lack of repair skills is and always has been my problem. If I fixed computers the way they fix cars, I'd be swapping out parts all the time and nothing would really get fixed! If I were you I would search out another Hyundai dealer since your car is so new. Good luck.

I have a 2001 Sonata with about 90K miles and the dealer service dept. just replaced the Input & Output Speed Sensors, which set me back ~$300. Since picking up my car the engine, which was purring like a kitten, has been running very rough and as of yesterday the tranny is back to shifting funny again. I'm calling the service dept. today so we'll see what happens. Needless to say, if your dealer wants to replace your speed sensors, GET A SECOND OPINION. I'm out $300 bucks already. Typical car dealer crap, keep swaping parts & maybe you'll trip over the actual problem!!
#56 of 339 Wats worng with my new 2009 Sonata Limited V6
Aug 28, 2008 (3:13 pm)
Recently bought a 2009 Sonata limited V6 with NAV, ......and now its 350 plus miles and since past 2 days... the engine cries(noisy) like anything....when I start the engine and till the time it reaches 0-35 mph(with jerks while it shifts the gears), it feels like I am driving a used car/truck. Real terrible...no pickup...even if its a V6.
One of the dealers said it needs 89 Ocatne gas....I should not put 87 Ocatne..where as per my user manual... 87 Octane gas is fine.
Where as the dealer from whom I bought the car asked me to get the car tomow. to their service center..... as they said they r going to fix it..if not then replace the car. Where as its not typically expected of a new car if it really passed Quality tests.....
Let me know if anyone had similar problem in the past......??
