Basic checks and adjustments on the car (A4A42)

Checking the oil level (ATF) automatic transmission in

Keep the car for a while until oil (ATF) in PPC reaches normal operating temperature (70-80 ?� C).

Place the vehicle on a flat, horizontal surface.

Press the brake pedal and move the selector lever through all of the provisions of (holding it in each of them for a few seconds) to fill the oil (ATF) automatic transmission control all hydraulic torque converter and automatic transmission, and then set the selector lever in position ?�N?�.

Before removing the dipstick, clean the dirt from the seat beside him. Remove the dipstick and check the oil in the PPC (ATF). Under the following conditions need to perform overhaul of the gearbox:

- Oil (ATF) in the automatic transmission has a burnt smell;

- Oil (ATF) in the automatic transmission has a markedly black;

- Oil (ATF) automatic transmission in a large number of contaminated metal particles.

Check the oil level (ATF) in the automatic transmission in the range of "HOT" dipstick. If the oil level (ATF) below this, top up to the mark "HOT".

Oil for automatic transmission fluid (ATF): GENUINE HYUNDAI ATF SP-II M.

If the level of oil (ATF) in automatic transmissions is below normal, the oil pump will capture oil together with air, which will result in different faults. The air got together with the oil (ATF) in the hydraulic lever, forms bubbles that cause oil foaming. As a result, the pressure in the hydraulic system becomes unstable, which in turn will lead to a delay in changing gear (later including transfers) and slipping clutches or brakes, etc. If the level is higher than normal due to the rotation of the planetary gear mechanisms arise copious foaming oil (ATF), which will ultimately lead to the same consequences as in the low-oil (ATF), and cause premature deterioration of the oil.

In both cases, air bubbles cause overheating, oxidation of the oil (ATF) and lacquer deposits, which disables the valves, clutches and actuators. Foaming also leads to the release of oil (ATF) automatic transmission through the crankcase breather that is mistaken for a leak.

Make sure that carefully studied the state of the automatic transmission oil (ATF) oil level on the dipstick before setting it in place (Fig. 3.72).

Testing the selector lever

Move the selector lever through all positions, check the smooth movement of the selector lever and steering. Check the indexing position of the selector lever.

Make sure that the selector lever can be switched to each position.

Start the engine and make sure that when you switch from ?�N?� to ?�D?� car moves forward and when you switch to ?�R?� - ago.

When the selector lever malfunctions, adjust control cable and clutch automatic transmission selector lever. Check moving parts of the mechanism of the selector lever assembly for wear.

Adjusting the switch of blocking of a starter (switch selector lever)

Set the selector lever in position ?�N?� (neutral).

Loosen the lock nut securing the automatic transmission control cable to manual control lever (manual control lever) (Fig. 3.73).

Set the manual control lever in position ?�N?� (neutral).

Loosen the screws locking switch and turn the starter switch housing so that an opening of 12 mm at the end of the manual control lever is aligned with a hole 12 mm in the flange of the breaker body (Fig. 3.74).

Tighten the switch to the specified torque with no change in the position switch.

Tightening torque bolts locking switch starter: 10-12 Nm.

Make sure that the selector lever is in position ?�N?� (neutral).

Adjust the cable tension control lever flange nut so the cable was a little tense, and then check the smooth movement of selector lever (Fig. 3.75).

Perform a road test and check compliance with each position includes a range selector lever and make sure the transmission works fine on each of the ranges.

Adjusting the brake servo forced downshift

Completely remove all dirt and other particles around the adjusting screw servo brake forced downshift.

Loosen the lock nut.

Repeat twice the operation tightening the adjusting screw until 5 Nm and the subsequent weakening.

Then tighten the adjustment screw tightening torque 5 Nm and then unscrew the adjusting screw in the range 3-31 / 3 turns.

Tighten the locknut to the specified torque (Fig. 3.76).

Tightening torque lock nut: 15-22 Nm.

Adjusting the pressure in the main magistali

Drain the oil (ATF) of the automatic transmission.

Remove the automatic transmission oil pan.

Remove the oil filter.

Remove the oil temperature sensor for automatic transmissions (Fig. 3.77).

Click on the tabs of the sealing sleeve harness solenoid valves and push it inside the gearbox (Fig. 3.78).

Remove the control valve assembly (valve body assembly). Valve range selection (manual valve) may fall, so be careful not to drop the valve (Fig. 3.79).

Turn the adjustment screw of the pressure regulator and adjust the pressure in the main line (supplied to the brake forced downshift (kickdown brake pressure), so that it corresponds to the nominal value (Fig. 3.80).

When the adjustment screw on the pressure regulator clockwise pressure in the main line decreases, turning the adjusting screw counter-clockwise - increases.

Standard value: 860-900 kPa.

Changing the oil pressure at each turn of the adjusting screw 38 kPa.

Check that the O-ring is properly installed on the upper surface of the control valve.

Replace a new O-ring sealing sleeve harness solenoid valves.

Install the control valve body in the transmission housing, and then insert the sealing sleeve inside the harness solenoid valves in place. When installing, make sure that the protruding part of the connector positioned as shown in Figure 3.78. Be careful not to pinch the wires.

Tighten the control valve assembly torque 10-12 Nm.

Install the automatic transmission oil filter.

Install a new oil pan gasket and oil pan.

Pour the nominal amount of oil (ATF) in the automatic transmission.

Test the pressure in the hydraulic control lever. If necessary, repeat the adjustment pressure.
