11.2.2. Changing the gearbox oil

• Place the vehicle on a level floor and remove the tachometer gear.
• Unscrew the gearbox shown in the picture on the bottom side 171 plug and drain the oil into a container that should have a capacity of more than 3.5 liters.

Clean the plug thoroughly and screw it back in. Using a watering can and a hose, pour oil through the hole for the tachometer gear. The required oil quantity is 3.5 liters and only Dextron II or M III should be used, however, SAE 80W-90 or SAE 90 oil can also be used. It is best to reuse the oil that was in the gearbox.
