Is there a generic transmission fluid for a 07 Kia Optima 4 cyl auto trans

This info should be in your owners manual.
The 4 speed trans shows a total fill of 8 quarts and the 5 speed shows a total fill of 10 quarts. Just changing the filter should be half that amount for each transmission.
There are trans fluids for multi-brands of import cars, Dextron may also work.
Again, check your owners manual or look on the dipstick.

Keep driving it like that & it won't work at all

When ever you even think you have a transmission
issue,you immediately stop using the vehicle or you
end up rebuilding the trans,your call,your money & lots of it

Ask yourself ---Why would changing the fluid do anything?

Old oil out / New oil in ?

You change trans fluid because it breaks down from the heat
That is it's job,to remove heat or your trans fails

Trans & Power Steering get changed every 3 years & not
over 30,000 miles ever on ALL Vehicles

power steering pump probably went out.. if you can easily get at the belt and are any kind of mechanically inclined, remove the drive belt to the p/s pump and then start the car if the noise is gone then its probably part of the power steering pump

Should be on the trans unless its a sealed trans.

there is alot of problems on these cars with throttle bodies being defective, suspect that first

Next time buy a manual and dont be so lazy ,Sounds like its lost a pump of a brake band thats controling these gears beacuse they are on the second eplycyclic

no serviceable filter in transmission. Kia requires trans.fluid to be changed every 30,000 miles. A simple drain and fill will do.

bottom of the engine at the transmission.

I had the same problem... just got my car services and took car to transmission spec. they told me that its the pump inside the tranny thats broken or something. while the pump is working >ie under acceleration it blows fluid out the seal (which seal im unsure) once the fluid level drops below the seal level it wont blow as much fluid out. if you check the levels you should notice that the fluid is well under level. Major job because you need to remove the transmission to get to the problem If that isnt the problem another issue could be a seal on the left or right driveshaft.This isnt as major as the other because you wont need to remove the transmission but time is required to remove the driveshafts to replace the seals. The first problem cost me about $600AU

from what i can gather there is no filter replacement, only a fluid exchange. this info is coming from a rather good borderline great mech. program.
