Automatic Transaxle System (F4A42): Removal & Installation Hyundai Sonata V 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 212

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 via the 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 the 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 (A) into the oil filler tube.

Scheme 216

1. Pull up the parking brake.
2. Position the shift lever in 'N' range.
3. Remove the air cleaner assembly.
4. Remove the battery.
5. Remove the battery tray (A).
6. Remove the inhibitor switch connector.
7. Remove the shift cable mounting nut (A).
8. Remove the inhibitor switch loosening the mounting bolts.
9. Referring to 'INSPECTION', check for continuity. If there is an error, replace the inhibitor switch.
10. After tightening the shift cable mounting nut, connect the inhibitor switch.
11. Install the battery, battery tray and the air cleaner assembly.

Scheme 217

Scheme 218

1. Check for the starter motor when the ignition switch is at 'START' position and the shift lever at 'P' or 'N' range.
2. Check for the rear lamp when the ignition switch if it does not work properly.
3. Check for the inhibitor switch if it does not work properly.
4. If the inhibitor switch is not fixed in a proper position, reassemble it in the right position.
5. Re-check 1 and 2 procedures.
6. Using a scan tool, confirm the DTCs.
7. Disconnect the battery (-) terminal and the inhibitor switch.
8. Check for continuity between terminals at the switch connector.
9. If there is not continuity between the terminals in the table above for each switch position, replace the inhibitor switch.

Scheme 221

1. Set the select lever to the "N" position.
2. Loosen the control cable to manual control lever coupling nut to free the cable and lever.
3. Set the manual control lever (A) to the neutral position.
4. Loosen the transaxle range switch body mounting bolts and then turn the transaxle range switch body so the hole in the end of the manual control lever and the hole (cross section A-A in the figure) in the flange of the transaxle range switch body flange are aligned.
5. Tighten the transaxle range switch body mounting bolts to the specified torque. Make sure at this time that the position of the switch body did not move. TORQUE : 10~12Nm (100~120kgf.cm, 7~8lbf.ft)
6. Gently pull the transmission control cable in the direction of the arrow, and then tighten the adjusting nut (A).
7. Check that the select lever is in the "N" position.

Scheme 222

1. Remove the automatic transaxle assembly.
2. Remove the valve body cover.
3. Disconnect the oil temperature sensor connector.
4. Remove the oil temperature sensor (B), loosening the mounting bolt (A).
5. Replace the sensor with the new one and reassemble the rest of the parts.

Scheme 223

Scheme 224

1. Remove the oil temperature sensor (A).
2. Measure the resistance between the terminal 1 and 2 of the sensor connector. TERMINALS RESISTANCE CHART Temp.[°C (°F)] Resistance (Kohms) 0 (32) 100 (212) 18.6 0.63
3. If the value is out of the specification, replace the oil temperature sensor.

5. Apply a light coat of automatic transaxle fluid to the O-ring seal before installation.
6. Install the input shaft speed sensor.
7. Install the control cable mounting bracket.
8. Connect the input shaft speed sensor connector.
9. Install the holder of the control cable.
10. Adjust the control cable to transaxle range switch and tighten the transaxle manual lever to the control cable mounting nut (see «ADJUSTMENT»(ref-286597-S20028307332008060300000) ).
11. Installation is the reverse of removal.
