You need to change the fluid but there is no filter that I heard of.
Mine was changed when my dealer tried to fix my trans leak the second time.. paid about 200. ..I swear they pumped it through the radiator cooler lines of the trans.
They dropped my trans to fix this last time..seems to be holding up.. I assume they changed it again and got all the orange dye out.
Think there was a procedure on here and I recall a youtube video..

I work at Napa auto parts and today I looked up a tranny filter for the sonic we list one for a 4L90 4spd Honda transmission 18 bolt trans pan that was the listing we show on the computer for the 012 sonic.

Also do I have to remove that plastic guard that's under the engine tranny to get access to the transmission drain plug?

I could see the trans drain plug on my car without removing anything.
I have 2012 Automatic and I haven't changed my transmission fluid ever. I just realized I should.
Dealer or replace it myself?

The owners manual for my 2015 1.8 with AT days to change the tranny fluid at 45,000.

Double-check your manual. I think that's only on the 'Severe' (commercial) schedule. The 'Normal' schedule for my 2012 says 97,500mi for the first fluid change.
The vast majority of Sonic owners can ignore the severe schedule unless they feel they have too much money.
Have a 2012 Sonic 69k. Transmission fluid was dark black when first changed 3k ago. I changed it a second time when I just changed the oil again & will do it again until it shows clean. Don't understand why it was so black?
On a positive note I have never had to replace brakes?

Tranny filter
You won't be changing the transmission filter on this unless you can drop the transmission out of the car and then split the transmission case. The filters on the GM 6TXX transmissions are sealed inside, and you can't get to it through the valve body cover either. :sadbanana:

Sorry to bring up an old thread.
The fluid is black from carbon in the torque converter clutch.
The "slip" strategy used on these clutches sheds very fine carbon particles into the oil. A little makes the oil appear dark. Don't worry, it's normal.
And my wife's Sonic has 123K miles on the original brake pads, still plenty of lining left on them...

We have the 2015 Sonic sedan with 1.8l automatic .
Everything I read indicates it has a AT filter , but to service it , the transmission case must be split to remove it . Not a DIY procedure for this old fat man !
So , I have been doing a drain and fill every 20,000 - 30,000 miles in hopes that will help keep it from clogging up .
Note , the old Dexron 6 came out very dark / black !

I read the trans must be split to service the filter . Not a tipical DIY project .
Suggest frequent spill & fills .
