thoughts on this would be certainly appreciated.
if the Elantra is the same as 02 Sonata, but
the factory service manual has
instructions for replacing the
transmission fluid which go beyond just draining
1. Disconnect hose that goes between transmission and radiator. I
took it off at the radiator.
2. Start engine in neutral and run one minute.
Remove plug on transmission and drain fluid.
4. Replace drain plug and fill
5. Start engine and run one minute.
6. Reconnect hose removed in
7. Fill with fluid and you're good to go.
I did this and it took
around 8.5 quarts of fluid at $5.50 per quart.
The transmission holds a little
over 8 quarts. With 70,000 miles on
the car, the fluid ws not very dirty but it
is done. The Hyundai
fluid turns brown pretty quickly compared to normal
fluids so this may not be a good indicator of condition.
