Question about Hyundai Sonata

1 Answer

Automatic transmission not shifting gears

I have a 2006 Hyundai Sonata, 6 cyl. auto. with 122k miles. The problem is that when the car is put in gear, either reverse or drive, it acts like its in neutral- the engine revs, but the car doesn't move for a few seconds, then eventually goes into gear. This seems to happen more often when the engine is cold. Coincidentally, this started happening a few weeks after the car was in an accident- it was rear ended. Took it to the hyundai dealer and they said it needs a new tranny. I saw a video on youtube in which the owner found that something was spilled on the gearshifter- he cleaned the electrical connections and it was fixed. Coincidentally, when my car was rear-ended, a cup of coffee was spilled on the gearshifter and all over the interior. The guy on the video had a different issue, though- when his car was put in drive, it would go into 2nd gear, but would not shift at all, unless he put it in manual mode- then it would only downshift, but not upshift.

What you say is possible and should be check out as well. Run fault codes and look for faulty TCM and torque converter clutch solenoid and servo. IT would not hurt to have a pressure test done on the transmission as well to see it and mechanical damage was done in the accident as if there was it will be claimable from the accident

The input and output transmission sensors may be bad. My car had this malfunction. I replaced the sensors and have had no more problems.

SOURCE: Transmission or Engagement issue?

I had the same problem with my 2006 Forenza - the problem was the transmission range sensor. If you look under the hood, on the drivers side, you'll see your trans. cable connected to a round part that also has an electrical cable coming from it. That is it. Part costs $36.07 at (search for Neutral safety switch in the mechanical catalog).

Hello and welcome to FixYa!
You may just have system failure. As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for at least 5mins. before reconnecting it. This will reset the system and can get it back to it's normal operation.
If the problem still persists, I believe that you will need to have the torque converter replaced. This can be caused by a faulty or worn out torque converter as well.
Hope this helps and thank you for using FixYa! Have a good one!

Have you checked the transmission fluid? Sounds like it is probably low, automatic cars will do that when they are low, also thats probably what the check engine light is. There are several auto part stores that will check the code for you or even some mechanic shops will do it for free too. Good luck.

2006 Hyundai Sonata, 3.3 L V-6, automatic transmission. Transmission will not shift automatically (e.g. from D1 to D2, D3, etc.) When using Sport Shift, it will not stay in 4th gear unless I hold the...

Unfortunately, there is very little that an untrained person can do much more to an automatic transmission than check the fluid and make sure that it is getting coolant so that it doesn't get too hot.
I work on cars all the time, and have rebuilt two automatic transmissions. One I was lucky and got it exactly right (beginners luck) and the other one I didn't. After multiple trys and probably replacing good parts, I gave up and took it to a transmission shop. So unless you are either VERY LUCKY or trained to work on them, my advice is to bite the bullet and seak professional help.
