I have 2009 hyundai sonota 3.3lL and my trans overheated and started leaking fluid badly and would only stay in 3rd and reverse. I added fluid and got my full range of gears back long enough to make in home which was 5 min away. Later I checked and fluid was leaking again and car would hardly move. Mechanic's Assistant: What is the color and consistency of the fluid? And where exactly are you finding it? Color was very dark and felt gravely. Seemed to be leaking right under trans. Hard to tell because it had sprayed all over. I sprayed degreaser and wiped as much as i could. I have removed most components above so I could see if it was leaking from above and nothing. Also It does not seem to be leaking from the trans fluid pan. Im getting the po735 code on my scanner. Possibly the torque convertor? Im not looking to replace the trans since the car is not worth the cost of a rebuilt. I just want to see if I can fix it or scrap the car Mechanic's Assistant: Are you fixing your [Sonata](/topics-sonata/) yourself? What have you tried so far? Im attempting to try and fix it, but not familiar with transmissions. So far i have just been inspecting to find leak.

Good Morning, Can you tell what general area the fluid id coming out of ? Axle between engine and trans ?

Seems like the area of the axel on passenger side
Automotive Expert
does it look like it may be coming out of the axle seal ?

I was trying to get the car unstuck from a snow drift so i was shifting between drive and reverse a lot and my tire. I then saw a lot of smoke and could smell it burning. When i got car out and backed into my garage I noticed a large pool of fluid underneath. Thats when I lost all gears expect 3rd and reverse until i added a quart of fluid which temp gave me back all gears
Automotive Expert
that could have just overheated it , is it still leaking once you filled it back up ?

Its hard to tell. Im also throwing the po735 code which I know is just a general code so im trying to determine if I may need a rebuilt or I can fix. The car is not worth the money to rebuildit leaked out the next day as well when i added more fluid, but not as much
Automotive Expert
is it still driving ok ? Ill look up that code

Currently i have a lot removed because i also blew a [radiator](/topics-radiator-hyundai/) hose and did not get new ones yet. I have to put them on and fill the radiator. I took most of the components out to visualize the top of the trans, cooler lines and trans pan. I did not see evidence it was leaking from any of those areas
Automotive Expert
that code is for 5th gear incorrect ratio , usually those codes indicate an internal problem that would require an overhaul

Thats what im fearing
Automotive Expert
I believe your fears may be correct , i would get it cleaned up and drive it like it is if you can

Would i be able to tell more by removing the trans fluid pan to see if there is any metal?
Automotive Expert
If you do that then you are just confirming that its bad , you wont be able to fix anything from in there

I had noticed some slippage previous to this for the past few months as well, but no leaking and fluid level was ok
Automotive Expert
Its easy to overheat and mess up the transmission in snow
