Gear oil change

[D813YBB]

Could anyone please indicate where the gear box oil drain plug is located, and which size hex key I need to buy to open the gear oil filler hole? (1.6 S series Maestro with VW manual gearbox).

I want to change the gear box oil, but have never done this before.

Hi the drain plug is located in the final drive housing below the N/S drive shaft. The oil filler plug and the drain plug both require a 17mm allen key or similar to remove & refit them. The gearbox should be filled with SAE75 gear oil.

It is easier to fill the gearbox through the speedo drive hole, the only pitfall in doing that is the plastic drive gear which is supposed to be attached to the cable on rare occasions can work loose and be lost in the box if care is not taken withdrawing it. The cable is secured to the gearbox by a 7/16 bolt.
