Automatic transmission fluid replacement (Hyundai Elantra XD)

If the torque converter fluid is being replaced, also replace the transmission fluid. If the torque converter fluid is not being replaced, replace the transmission fluid as follows.

Procedure

1. Disconnect the hose that connects the gearbox and the oil cooler (from the radiator side). Remove the drain plug from the base of the transmission housing and drain the fluid.

2. Install the drain plug with gasket and tighten to specification torque. Tightening torque: 32 Nm.

3. Pour in the required amount of liquid.

Warning: Stop adding fluid if the required amount cannot be poured into the transmission.

4. If more transmission fluid was added, repeat the procedure according to step 1.

5. Reconnect the hose that was disconnected in step (1) and insert the dipstick securely.

6. Start the engine and let it idle for 1-2 minutes.

7. With the engine running, move the selector lever from the "N" position to all positions and back to the "N" position.

8. Drive until the gearbox warms up to 70–80°C. Park the car on a level horizontal surface. Check the fluid level, which should be between the "HOT" marks. If necessary, add the required amount of the required fluid.
