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

To check the oil level:

• check for errors using a diagnostic tool;
• raise the car on a lift or place the car horizontally on an inspection pit;
• set the selector to position "P" without applying the parking brake;
• connect the diagnostic tool;
• select the "Measure Parameters" function;

• unscrew plug 1 (figure 5.64) for filling oil;
• using a filling cylinder 0341 or a tube with a funnel at the end, fill the gearbox with 0.5 l of ESSO LT 71141 oil;
• with the engine running, heat the gearbox oil to a temperature in the range of 58 to 68°C;
• with the engine running, unscrew the oil level check plug. The plug has a hex head for a 19 mm wrench;
• if the oil flows out in a thin stream and then drips, then the oil level is normal. Update the oil wear counter;
• if the oil comes out in drops and then stops flowing, follow these steps:
• stop the engine;
• let the oil cool;
• add 0.5 liters of oil to the gearbox;
• repeat the procedure to check the gearbox oil level;
• replace the sealing gasket each time the oil level plug is removed.

Draining the oil for replacement must be done on a hot gearbox; to do this, take the car for a short drive (figure 5.65).

To change the gearbox oil:

• raise the car on a lift or place the car horizontally on an inspection pit;
• the oil can be drained only partially, and the volume of drained oil is approximately 4 liters;
• place a container to collect the oil under the oil drain hole and remove the plug 1 (see Figure 5.64) draining the oil. The plug has a hex head that fits a 27 mm wrench. If necessary, apply pressure to the plug when unscrewing it to prevent premature oil leakage. Drain the engine oil;
• when the oil has completely drained, wipe away any oil around the drain hole and screw in the oil drain plug with a new sealing ring, tightening it to a torque of 40 N·m;
• unscrew plug 2 (see Figure 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.

Volume of oil to be filled:

• after draining the oil - 4 l;
• after removing and installing the hydraulic unit housing - 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.

Important! Before performing any work, you must add at least 0.5 liters of new transmission fluid, update the oil wear counter using a diagnostic tool, and follow the oil level check procedure.
