How do you change oil seal in gear box 206?

To change the oil seal in a Peugeot 206 gearbox, first, safely lift the vehicle and secure it on jack stands. Drain the gearbox oil and remove any components obstructing access to the oil seal, such as the driveshaft or gearbox cover. Carefully pry out the old oil seal using a seal puller or flat tool, and then clean the sealing surface. Install the new oil seal by pressing it evenly into place, reassemble the gearbox, and refill with the appropriate oil.
