Where is the gearbox oil filler point on a 1998 1.00 Micra?

Answer 1

Re-filling your 1898 1.0 Micra gearbox is achieved by removing the speedometer drive cable from the rear of the gearbox adjacent to the startermotor solinoid, it is held in place by 1 x 10mm bolt.(It is tricky to get access to) Re-fill with 3.3 litres of fresh 80W90 gear oil after draining, and replace the speedo drive cable. Some 1998 onward models already changed to a different filler plug located much lower down in the gearbox housing and far easier to locate and access. It can be recognised as a round plug requiring a 3/8 inch square drive ratchet wrench to remove / re-tighten. Similar looking to the drain plug which requires a 1/2 inch square drive ratchet wrench to release and re-tighten. It is located toward the front of the engine about 4 inches from the bottom edge of the gearbox close to the drain plug.
