Note: A hex wrench is required to loosen the gearbox fill plug.
1. Place a suitable container under the transmission filler and inspection plug located on the right side of the transmission. To unscrew the plug, you will need a hex wrench, but if it is not available, you can use a tall nut or a piece of hex and a wrench (see fig. 18.1).

2. The fluid level should be at the level of the lower edge of the filler hole.
3. If necessary, add fluid until it starts to flow out of the filler hole.
4. When the level is correct, install the plug and tighten it securely.
