#### LEVEL CHECK

The oil in the manual transmission should be checked at least every 15,000 miles (24,000 km) and replaced every 25,000–30,000 miles (40,000–48,000 km), even more frequently if driven in deep water.

1. With the vehicle parked on a level surface, remove the filler plug from the transmission housing.
2. If the lubricant begins to trickle out of the hole, there is enough. Otherwise, carefully insert your finger (watch out for sharp threads!) and check to see if the oil is up to the edge of the hole.

3. If not, add oil through the hole until the level is at the edge of the hole. Most gear lubricants come in a plastic squeeze bottle with a nozzle; making additions simple.
4. Replace the filler plug and tighten it to 27 ft. lbs. (37 Nm). Run the engine and check for leaks.
