Transmission Fluid for the 2017 Subaru Forester

The 2017 Subaru Forester is a popular SUV known for its reliability and all-wheel-drive capability. When it comes to the vehicle's transmission system, one important aspect to understand is the role of transmission fluid. For Subaru models like the 2017 Forester, transmission fluid is very much relevant and essential, especially if the vehicle has the continuously variable transmission (CVT) that Subaru typically fits to their Forester line-up. If the 2017 Forester is equipped with a traditional automatic transmission or a manual gearbox, transmission fluid or gear oil still plays a critical role, but the most common setup is the CVT, which requires a specific transmission fluid type.

Transmission fluid has the main job of lubricating the moving parts within the transmission system. Without it, friction and heat can build up very quickly, leading to wear and potential damage of the internal components. The fluid also helps with cooling and assists in the smooth transfer of power from the engine to the wheels. For the Forester's CVT, the fluid also helps operate the unique pulley system that allows the vehicle to seamlessly adjust gear ratios for optimum performance and efficiency.

Subaru has developed and recommends a specific transmission fluid type for its CVT models, typically the Subaru High-Performance CVT Fluid. Using the correct fluid is important because CVT transmissions operate differently to conventional automatics or manuals, so generic transmission fluids may not provide the necessary lubrication, friction characteristics, or durability.

Regular maintenance of transmission fluid is a crucial part of keeping a 2017 Forester running smoothly. Over time, transmission fluid breaks down and becomes contaminated by heat, friction, and particles from internal wear, reducing its effectiveness. Subaru generally recommends replacing the CVT fluid every 60,000 km or so, but it is always a good idea to check the owner's manual or consult a Subaru technician for the exact interval based on driving conditions.

During a transmission fluid change, the old fluid is drained and replaced with fresh fluid that will provide the proper lubrication and cooling needed. This service may also include replacing the transmission filter if applicable. It is a job best carried out by professionals who can properly lift the vehicle, drain the fluid, check for leaks, and refill the fluid to the precise manufacturer specifications.

Ignoring transmission fluid maintenance can lead to a range of problems. For a CVT-equipped Forester, degraded fluid can cause overheating, poor acceleration, jerky or delayed response, and in some cases, permanent damage to the transmission components. Repairs or replacements of a damaged CVT can be very costly, so keeping up with fluid changes is a smart investment in the vehicle's longevity.

For owners who primarily drive in harsh or demanding conditions such as extreme heat, heavy towing, or mountainous terrain, it might be necessary to perform transmission fluid changes more frequently than the standard recommendation. Regular inspection of the fluid's colour and smell during servicing can indicate its condition. Healthy transmission fluid is usually a bright, clean red, while old or burnt fluid may appear dark brown or black and smell burnt.

In terms of DIY servicing, changing transmission fluid on a 2017 Subaru Forester CVT is generally not recommended unless the person has the right tools and a solid understanding of the transmission system. The process often requires an accurate measurement of fluid volume, and the use of the specified Subaru CVT fluid is critical. Incorrect fluid or improper filling can do more harm than good.

In essence, transmission fluid is relevant and crucial to the 2017 Subaru Forester, particularly models fitted with the CVT. It ensures the transmission operates efficiently, smoothly, and reliably while protecting key components from premature wear. Keeping up with recommended transmission fluid changes as part of regular servicing will help maintain the Forester's performance and help avoid costly repairs down the track.
