AUTOMATIC TRANSMISSION Identification 23A 23A-1 123A AUTOMATIC TRANSMISSION Identification Identification stamped on the automatic transmission. TECHNICAL SPECIFICATIONS Weight: 70 kg Vehicles fitted with DP0 automatic transmission use systems called Shift Lock and Lock Up. The aim of the Shift Lock is to prevent the gear lever from being moved unless the brake pedal is being depressed simultaneously. The aim of Lock Up, or converter bridging, is to connect the automatic transmission directly to the engine. This function is performed by a "mini clutch" located in the converter. Lock Up is controlled by the automatic transmission computer. As the automatic transmission is lubricated under pressure, lubrication is only provided when the engine is running. As a result of this fact, and to avoid serious damage, it is essential to comply with the following instructions: – never allow the vehicle to move with the ignition switched off (e.g. when going down a hill); we cannot stress too strongly the harm that this may cause, – never push the vehicle (e.g. to reach a petrol station), except taking the precautions contained in the "Towing" section. In addition, the vehicle can only be driven if the engine is running. It is therefore impossible to start the engine of an automatic transmission vehicle by pushing the vehicle. TOWING The vehicle should always be towed on a back-plate or with the front wheels raised. If this is not possible, the vehicle may, in exceptional cases, be towed at up to 30 mph (50 kph) for a maximum distance of 30 miles (50 km), with the gear lever in N position. Note: For repair operations when the battery is faulty, refer to the vehicle user's handbook. WARNING Towing weight (towing a caravan, boat, etc.). The load to be towed must be no greater than 1,300 kg for a DP0 automatic transmission. Failure to comply with this maximum load will, on a class 7% slope, result in the maximum engine oil and automatic transmission oil temperature being exceeded, causing damage to the system.

AUTOMATIC TRANSMISSION Lubricants 23A 23A-3 Lubricants The DP0 automatic transmission is lubricated for life, and it requires no maintenance; it should only be topped up if there is a small leak. OIL SPECIFIED: DEXRON III Standard automatic transmission oil CAPACITY IN LITRES: Total volume: 6 litres.

AUTOMATIC TRANSMISSION Parts always to be replaced 23A 23A-5 Parts always to be replaced Parts to be replaced when they have been removed: – self-locking nuts, – seals, – rubber seals, – converter nuts.

AUTOMATIC TRANSMISSION Oil changes 23A 23A-6 Oil changes OIL CHANGES Drain the automatic transmission oil when the oil is warm (60 °C maximum), in order to remove as many impurities as possible. Put the vehicle on a lift. Remove the engine undertray. Drain the oil by removing the plug (1). SPECIAL NOTES The plug has two functions: – draining the oil via the plug (1), – topping up via the spout (2). Tightening torques drain plug 2.5 daNm filler spout 3.5 daNm Note: As a precaution, measure the oil collected during the oil change (total or partial) to find out the volume of oil to be replaced and to prevent filling to the wrong level.

AUTOMATIC TRANSMISSION Filling and topping up 23A 23A-7 Filling and topping up FILLING Fill through the hole (1). Use a funnel fitted with a 15/100 th filter to prevent impurities from entering the system. FILLING PROCEDURE 1 - Park the vehicle on level ground. 2 - Fill the automatic transmission with 3.5 litres of new oil. 3 - Run the engine at idle speed. 4 - Connect the diagnostic tool and establish dialogue with the automatic transmission computer. 5 - Monitor the transmission oil temperature parameter. 6 - When a temperature of 60 °C ± 1 °C is reached, open the top-up plug. 7 - Position a container to retrieve at least 0.1 litre of excess oil and wait until the oil flows out one drop at a time. 8 - Close the top-up plug. PROCEDURE FOR CHECKING THE LEVEL OTHER THAN DURING FILLING OPERATIONS The level MUST be checked using the method described below: 1 - Park the vehicle on level ground. 2 - Fill the automatic transmission with 0.5 litres of new oil. 3 - Run the engine at idle speed. Perform operations 4, 5 and 6 described previously. If the oil does not flow out or the quantity collected is less than 0.1 litres: stop the engine, add 0.5 litres, let the automatic transmission cool down to 50 °C then carry out operations 3, 4, 5 and 6. When replacing the oil, the electronic oil ageing counter must be reset (inside the computer). Enter the oil change date using command CF074 "Record gearbox oil change date" on the diagnostic tool.

AUTOMATIC TRANSMISSION Checking the converter setting point 23A 23A-8 Checking the converter setting point Place the vehicle on a two-post lift Lift the vehicle until the wheels are raised off the ground by a few centimetres. Connect the diagnostic tool. Establish dialogue with the automatic transmission computer. Monitor the automatic transmission oil temperature parameter. The check should be carried out when the oil temperature is between 60 °C and 80 °C. Start the engine and put the lever in (D). Monitor the engine speed parameter. Establish dialogue with the computer. Accelerate fully keeping the brakes on. The front wheels should not rotate. The engine speed should stabilise at: KUBISTAR → 2,500 ±150 rpm. A setting point outside the tolerance requires that the converter be replaced. WARNING – Maximum acceleration should not be maintained for more than 5 seconds. Beyond this, there is a high risk of damaging the converter or the automatic transmission. – Once the measurement has been taken, release the accelerator and keep the brakes on until the engine speed stabilises at idle speed (risk of damaging the automatic transmission if this is not done). Note: A setting point which is too low may be due to a lack of engine power.

AUTOMATIC TRANSMISSION Hydraulic distributor 23A 23A-9 Hydraulic distributor REMOVAL Put the vehicle on a two-post lift. Remove the engine covers. Disconnect the battery. Drain the refrigerant circuit using a filling station. Remove the engine undertray. Drain the cooling circuit through the radiator bottom hose. Drain the automatic transmission through the cap (1). Special tooling required B.Vi. 1462 Ball plate adjusting screw Tightening torques cover mounting bolt 1 daNm distributor mounting bolt 0.75 daNm rechargeable battery 4 daNm Note: During this operation, the vehicle must be secured to the lift with a strap to prevent it from becoming unbalanced. For the strap attachment procedure, see the Lifting section.

AUTOMATIC TRANSMISSION Hydraulic distributor 23A 23A-10 Remove: – the resonator (2), – the battery, – the two connectors (3), – the bolt (3). Release the electric wiring harness from the battery tray. Remove: – the four bolts and the nut (4) of the battery tray, – the battery tray. Remove the radiator (refer to the relevant section). Remove the modular connector by releasing the connector module (5). Remove: – the three mounting bolts (6) from the modular connector support plate, – the two mounting bolts from the modular connector plate, then remove the connector, – the connector, – the connector tabs so that the harness can be extracted from the gearbox, – the hydraulic distributor harness clip attached to the gearbox. Undo the power assisted steering pipe mountings on the gearbox.
