Change Interval for Transmission Fluid

Changing your transmission fluid at the right intervals is crucial for maintaining the health of your Chevy’s transmission. While many owners are aware of the importance of oil changes for their engines, transmission fluid often gets overlooked. Here’s a breakdown of recommended change intervals and the rationale behind them.

Recommended Change Intervals

The change interval for transmission fluid can vary significantly based on the type of transmission, driving conditions, and manufacturer recommendations. Here are some general guidelines:

• Automatic Transmissions: Most manufacturers recommend changing the transmission fluid every 30,000 to 60,000 miles (48,000 to 96,000 km). However, some newer models may extend this interval up to 100,000 miles (160,000 km) under normal driving conditions.
