Automatic Transaxle System: Removal & Installation Kia Optima II рестайлинг

REPLACEMENT

If you have a fluid changer, use this changer to replace the fluid. If you do not, replace it using the following procedure.

Scheme 4

1. Disconnect the hose which connects the transmission and the oil cooler which is within the radiator only in 2.4L engine(3.3L-the oil cooler is separated).
2. Start the engine and let the fluid drain out. Running conditions : "N" range with engine idling. CAUTION: The engine should be stopped within one minute after it is started. If the fluid has all drained out before then, the engine should be stopped at that point.
3. Remove the drain plug(A) from the bottom of the transmission case to drain the fluid.
4. Install the drain plug using a new gasket, and tighten it to the specified torque. TORQUE : 40 ~ 50Nm (400 ~ 500 kgf.cm, 29 ~ 36 lb-ft)
5. Pour the new fluid in through the oil filler tube. CAUTION: Stop pouring if the full volume of fluid cannot be poured in.
6. Repeat the procedure in step (2). NOTE: Check the old fluid for contamination. If it has been contaminated, repeat steps 5 and 6 .
7. Pour the new fluid in through the oil filler tube.
8. Reconnect the hose which was disconnected in step (1) above and firmly replace the oil level gauge.(In case of this "replace", this means after wiping off any dirt around the oil level gauge, insert it into the filler tube.)
9. Start the engine and run it at idle for 1~2 minutes.
10. Move the select lever through all positions, and then move it to the "N" position.
11. Drive the vehicle until the fluid temperature rises to the normal temperature (70~80°C), and then check the fluid level again. The fluid level must be at the HOT mark.
12. Firmly insert the oil level gauge into the oil filler tube.
