Car Care Tips
On a manual transmission, it may be necessary to change the fluid if you were experiencing hard shifting problems during cold weather. Most older rear-wheel drive transmissions use a heavy gear oil like 75W, 80W or 90W, which can get pretty stiff at subzero temperatures. Changing to a lighter oil may improve shifting.
According to the Automatic Transmission Rebuilders Association, 90% of ALL transmission failures are caused by overheating. Most of these can be blamed on worn out fluid that should have been replaced. For optimum protection, change the fluid and filter every 30,000 miles. With today's automatic transmissions the correct type of transmission fluid is critical to the life of your transmission. Use of the wrong fluid can actually cause transmission failure itself. In order to protect your transmission, we highly recommend that you have your transmission serviced by a shop who knows which fluid is the correct application for your vehicle and its particular transmission.
