How much transmission fluid is in a 2005 Hyundai Elantra 2.0L automatic and how is it changed?

go to the dealer as it is a special fluid, yous should take it in every 25000 kilometers and it cost about 90.00 in Canada.They just drain it from the drain pan so not all the fluid is drained out of the torque converter, YOUR MANUAL GIVE YOU THE QUANTITY ALSO
