Mitsubishi 380 Gearbox & Transmission Problems

Use the manual shift as much as you can and anticipate the road ahead. When you're facing a hill, be ready to down-change manually without waiting for the transmission to do it for itself. Never let it lug at low revs in too high a gear. The other thing to be mindful of is servicing. The transmission fluid should be regularly changed, at least every 50,000 km if not before, and a full service is recommended around 100,000 km. By doing that you should be able to extend the life of your automatic transmission. Servicing is even more important if the transmission is made to work hard, such as when towing.
