Checking the level and changing the oil in the gearbox (Peugeot 307)

To check the oil level:

• check for errors with a diagnostic tool;
• raise the car on a lift or place the car in a horizontal position on an inspection ditch;
• set selector to position «P», not including the parking brake;
• connect the diagnostic tool;
• select function «Parameter measurement»;

• remove plug 1 (pic. 5.64) for filling oil;
• using filling cylinder 0341 or a tube with a funnel at the end, fill the gearbox with 0.5 liters of ESSO LT 71141 oil;
• with the engine running, heat the gearbox oil to a temperature between 58 and 68°C;
• With the engine running, remove the oil level plug. The plug has a 19 mm hex head;
• if the oil flows out in a thin stream and then drips, then the oil level is correct. Update the oil wear counter;
• If oil drips out and then stops flowing, follow these steps:
• stop the engine;
• let the oil cool down;
• add 0.5 l of oil to the gearbox;
• repeat the operations to check the oil level in the gearbox;
• Replace the seal every time you remove the oil level plug.

Draining the oil for replacement must be carried out on a hot gearbox, for this, spend a short drive in the car (pic. 5.65).

To change the gearbox oil:

• raise the car on a lift or place the car in a horizontal position on an inspection ditch;
• the oil can only be drained partially, the volume of the drained oil being approx. 4 l;
• place an oil collecting container under the oil drain hole and unscrew plug 1 (see fig. 5.64) oil drain. The plug has a 27mm hex head. If necessary, press the plug when unscrewing, so that the oil does not leak prematurely, drain the engine oil;
• when the oil is completely drained, wipe off the oil around the drain hole and screw in the oil drain plug with a new sealing ring, tightening it to 40 Nm;
• remove plug 2 (see fig. 5.65) for filling oil;
• Using filling cylinder 0341 or a tube with a funnel at the end, fill the gearbox with ESSO LT 71141 oil.

Filled oil volume:

• after draining the oil - 4 l;
• after removal and installation of the crankcase of the hydraulic block - 1.5 l;
• after draining the fluid and replacing the hydraulic unit - 4.5 l;
• after draining the fluid and replacing the torque converter - 5 l.

Attention! To carry out any work, add at least 0.5 liters of new oil to the transmission, update the oil wear gauge using a scan tool, and follow the oil level check procedure.
