Removing
Raise and secure the vehicle on lifts.
Disconnect the battery.
Remove:
- front left wheel;
- front left fender liner;
- protection under the engine;
- protection under the front bumper.
Drain the oil from the automatic transmission (see corresponding operation).
Remove the air filter unit. Remove the pipeline (2) and support (3).
Disconnect the heat exchanger inlet and outlet air tubes.
unscrew the bolt (4) and remove the heat exchanger (5) (see corresponding operation).
Remove the 11 hydraulic block housing mounting bolts (6).
Note. The crankcase of the hydraulic block is mounted on sealing paste.
Attention. The hydraulic block crankcase contains approximately 0.5 liters of oil.
Disconnect the eight solenoid valve connectors (2) (in the zone «A») and two speed sensor connectors (in the zone «b») with a thin screwdriver. Remove the bolt (7) and remove the oil temperature sensor (8).
Loosen two screws (13) and remove the cover (14).
Unfasten and move the wiring harness (10).
Note. Oil temperature sensor (8) connected to wiring harness (10).
Loosen six bolts (15) (in sequence from 1 to 6).
Remove the hydraulic block (9), pulling out the traction (11).
Attention. Hold the hand valve in place (12) hydraulic connector (9).
Handle the hydraulic unit carefully and protect it from any contamination.
Installation
Reinstall the hydraulic block (9), by inserting traction (11) into the gear shifter.
Location of solenoid valves in the hydraulic unit:
16 - solenoid valve for modulating the torque converter blocking pressure;
17 - clutch pressure change solenoid valve «C3»;
18 - brake pressure modulation solenoid valve «IN 1»;
19 - secant valve «S1»; 20 - secant valve «S2»;
21 - solenoid valve for pressure modulation in the circuit;
22 - clutch pressure change solenoid valve «C2»;
23 - clutch pressure change solenoid valve «C1».
Attention. Correctly position the wiring harness (10) in his fastenings and his nest (in the zone «With»).
Do not pinch speed sensor wiring harnesses (24) And (25).
Install in place:
- six bolts (15) (tighten by hand);
- cover (14) (with new seal);
- two bolts (13) (tighten by hand).
Tighten the bolts (15) And (13) torque 10 Nm (in sequence from 1 to 8).
Install the oil temperature sensor (8) and bolt (7).
Connect eight solenoid valve connectors (2) (in the zone «A») and two speed sensor connectors (in the zone «b»).
Attention. Check the positioning and fastening of the wiring harness (10).
Check that the gearshift mechanism works properly in all positions.
Clean the surfaces to be joined.
Apply a layer of sealing paste to the crankcase of the hydraulic block (6) (type «Loctite black tite»).
Install the 11 hydraulic block housing mounting bolts (6) and tighten to 15 Nm.
Connect the battery.
Change and top up the oil level in the automatic transmission (see corresponding operation).
Update the oil wear counter using a scan tool.
Complete «education» adaptation of solenoid valves and oil pressure regulators (in case of replacement of the hydraulic unit).
Install heat exchanger (see corresponding operation). Connect the inlet and outlet air tubes of the heat exchanger. Install the rest of the parts in reverse order.
