Hi, i have 2007 Hyundai Elantra with 1.6 engine.
I had my ATF changed recently. i used Q8 auto 15 transmission fluid and right after the change as soon as i turn the engine on, 3 and 2 starts to blink on instrument cluster. When parked P light is on, when driving D is on but still 3 and 2 keeps blinking all the time. When i shift to L, EPS starts to blink too. I dont feel any other problem while driving. The shifting is normal too.
Why do you think could it happen?
Thanks in advance

 

Who changed the trans fluid? How long ago? Did they use the correct type? Take it back to them.

 

Just a little side note, there have been many changes to auto transmissions and among the changes are the required fluid to be used. Almost every manufacturer has their specific fluid required and if the incorrect fluid is used all sorts of problems appear. Best to get the fluid right from Hyundai dealer.

 

Thank you guys very much,
The atf that is used is this one, Q8 Auto 15 - Transmission Fluid | Q8 Oils | Rix Petroleum
I had it changed in a local service 4 days ago.
According to the car manual, ATF SPIII must be used and it shouldn't be problem.
I took the car to diagnostics center, they checked for any code error but didn't find any. They suggested to change the fluid again with the right one. And thats what im probably gonna do. But the thing is, i don't feel any other problem. it shifts ok, it accelerates ok. No other problem other than 3,2 and sometimes L blinking. I wonder if it would be problem if i continued driving.
I recorded the problem and uploaded on Youtube. This is what happens as soon as i start the engine.

 

Looks like an electrical problem, not a physical trans problem. Get the trans computer look at by a dealer.
