Then Hyundai has foistered one of the biggest cover-ups in automotive history, that is, they put 5-speed automatic transmissions on their Sonata I4s sold in the U.S. for 1-2 years but told the world that it was only a 4-speed automatic. Also, they put these 5-speed automatics only on SOME 2007-2008 Sonatas. I've driven maybe a half dozen of these cars and they all had 4-speed automatics.
 
I can post a few dozen links to Web pages that state clearly that the 2006-2008 Sonata I4s sold in the U.S. have 4-speed automatics. Can you post some proof of your claim that 2007-2008 Sonata I4s had 5-speed automatics? If not, can we move on?

The automatic in the online factory shop manual (www.hmaservice.com) listed for the 2008 Sonata I-4 2.4L is the F4A42, with specs that state it is a FOUR SPEED automatic. IF there had been a 5-speed auto in any of those 2008 cars, it would be referenced in the shop manual. Any Hyundai mechanic who says there were 5-speed auto transmissions in the 2008 4-cylinder cars is, quite simply, wrong and uninformed. I'd not let that mechanic near my car.

It's a 2002 with 54,000. The warranty is up. I just got the car back and it cost $255 to have the job done. Quite a difference from the $900 I was quoted !!!

o.k. let me explain to you..
 
when you driving the car and the Gear switch the speed automatcliy the rpm going down.
 
try to drive manualy till you will get to the 4 speed. then switch it to auto keep driving and you will see that the RPM is going down and change to 5th speed auto.
 
now that i have the problem with the transmission no one from the menufactor denid that on my car there is 5th gear. also the master tech confirmed that.
 
if you what is RPM you will see i am right.

It was already mentioned that what you are feeling is the torque converter going into lockup mode, which can feel a lot like a gear change and results in the RPMs going down.
 
Here is an article that describes the operation of the lockup torque converter, in general. Note this particular phrase:
 
If you have a tachometer you will see the RPM's drop a few hundred when it engages.

Hope this helps.

backy has already explained what you are seeing. Unless you have an '09, you do not have a 5 speed automatic on a 4 cylinder Sonata. No amount of "observations" or lack of technician feedback will convince me that you do. Crawl under the car and read the model plate on the transmission itself. If it is something other than what I referenced in my previous post, let me know.

Dear Backy,
 
This is Funny, i think Hyundai should pay you for the public relation that you are doing for them...or they already paying you?
 
if it was not a problem no one was keeping my car at the shop for so long and trying to fix it.(ohhh and not only my car, i know more then 2) if it was not a problem the tech would not have on the website answers how to fix it (by installing the program).
 
dont you think at the first time that i went to the Shop they needed to say "what you are feeling is the torque converter going into lockup mode" and send me home?

Did it occur to you that a transmission can have a problem that is fixed by installing a program, without the transmission being a type that is not available on your car?
 
For example, here's a TSB for the 2008 Sonata's automatic transmission that requires an ECM/TCM update, i.e. reprogramming:
 
http://www.edmunds.com/maintenance/recalltsb.do?step=tsb&year=2008&make=Hyundai&- - model=Sonata&style=GLS+4dr+Sedan+(2.4L+4cyl+5M)#2
 
Perhaps you could ask the dealer if this TSB applies to your Sonata. Notice I found the info on a web site--maybe like the service tech did!
 
What I think is funny is that you continue to hold onto this ridiculous story about your car having a 5-speed automatic in it when no 2008 Sonata 4-cylinder sold in the U.S. came so equipped.
