How much transmission fluid goes in a 2005 Sonata

Question:

I have a 2005 Hyundai Sonata. I just need to know what to do to change the transmission oil and how much does it need?

Answer:

The total capacity is 8.5 qts. Simply draining the pan does not get all fluid out of system, so drain and fill capacity is usually about 3-4 qts. Remove the drain plug, drain the fluid, note amount drained out, and take care to check level frequently when filling so not to overfill.
Hyundai recommends using only Hyundai SP111 trans fluid.
