Does Subaru recommend transmission flush or change?
Subaru recommends that owners follow the maintenance schedule outlined in their vehicle's owner's manual, which typically calls for a transmission fluid change rather than a flush. The automaker advises against performing a transmission flush, as it can potentially cause more harm than good to the vehicle's transmission system.
Subaru's Transmission Fluid Maintenance Recommendations
According to Subaru's guidelines, the transmission fluid in their vehicles should be changed at regular intervals, typically every 30,000 to 60,000 miles, depending on the model and driving conditions. This fluid change is a straightforward process that involves draining the old fluid and refilling the system with the recommended type and amount of new transmission fluid.
Subaru cautions against performing a transmission flush, which involves using a machine to forcibly circulate new fluid through the system and flush out the old fluid. While this may seem like a more thorough cleaning process, Subaru warns that it can actually dislodge built-up deposits and cause them to clog the transmission's internal components, leading to potential damage or failure.
Why Subaru Recommends Fluid Changes Over Flushes
- Preserves Transmission Components: Subaru's transmission systems are designed to operate with the specific type and amount of fluid specified in the owner's manual. A flush can disrupt the delicate balance of the transmission, potentially causing premature wear or damage to the internal components.
- Avoids Dislodging Deposits: Over time, small amounts of debris and deposits can accumulate in the transmission. A fluid change gradually removes these, while a flush can dislodge larger amounts, leading to clogging and other issues.
- Maintains Proper Fluid Levels: Subaru's recommended fluid change process ensures that the correct amount of new fluid is added, maintaining the proper levels and lubrication for the transmission.
By following Subaru's recommended maintenance schedule and opting for fluid changes rather than flushes, owners can help ensure the long-term health and performance of their vehicle's transmission system.
