In most 2014 Forester models, the transmission is a Lineartronic CVT and is typically sealed, meaning there isn’t a user-accessible dipstick for easy level checks. If your car does have a transmission dipstick, you can check the level when the engine is warm and the transmission is in Park. If your vehicle uses the sealed CVT setup, servicing and level checks are generally handled by a dealer or qualified technician. Here’s how to approach both scenarios and what to know for maintenance and potential issues.
Dipstick-equipped transmissions (rare on the 2014 Forester)
How to determine if you have a dipstick and how to check
If your Forester has a transmission fluid dipstick, follow these steps to check the level safely and accurately. Always refer to the owner’s manual for exact locations and temperature ranges corresponding to the marks on the dipstick.
- Park the vehicle on level ground and set the parking brake. Start the engine and let it reach normal operating temperature, typically indicated by the temperature gauge or as described in the manual.
- With the car in Park (P) and the engine running, locate and remove the transmission dipstick. Wipe the dipstick clean with a lint-free cloth.
- Reinsert the dipstick fully, then remove it again to read the fluid level. Check the level while the transmission is hot; the level should be between the hot marks on the dipstick.
- If the level is low, add the CVT fluid recommended by Subaru through the dipstick tube in small increments, rechecking after each addition. Do not overfill.
- After verifying the level, reinsert the dipstick and ensure the cap is securely seated. If you’re unsure or uncomfortable performing this, have a Subaru-certified technician complete the check.
When using a dipstick, always use the fluid type specified by Subaru for your transmission and avoid mixing with other fluids. Incorrect fluid or overfilling can cause shifting issues or CVT damage.
Sealed CVT (the common setup for the 2014 Forester)
What you can do at home and what to expect from service
Most 2014 Forester models rely on a sealed Lineartronic CVT, which means a driver-level dipstick check isn’t available. The following guidance helps you understand maintenance expectations and how to respond to potential symptoms.
- Know the maintenance schedule: The CVT fluid service interval varies by market and usage. Check your owner's manual for the recommended interval and follow Subaru’s guidelines. Severe conditions (heavy towing, frequent stop-and-go urban driving, extreme temperatures) may require more frequent service.
- Use the correct fluid: Only use the CVT fluid specified by Subaru for your transmission. Using the wrong fluid can degrade performance and cause damage. Do not mix CVT fluid with other transmission fluids.
- Be aware of symptoms that may indicate low or degraded CVT fluid: slipping or lag in acceleration, shuddering during takeoff, overheating warnings, reduced fuel efficiency, or any abnormal noises from the transmission. If you notice these, have the fluid level and condition inspected by a dealer or qualified technician.
- When you must service the fluid: CVT fluid replacement, topping, or pan service is typically done by a trained technician with the proper equipment. If your vehicle shows signs of transmission trouble or you’re approaching the recommended service interval, schedule a service appointment rather than attempting DIY changes.
- Visit a Subaru-certified shop: A dealer or ASC-certified shop will have the correct tools, torque specs, and procedures to measure and adjust the CVT fluid level accurately and safely.
Because the CVT in many 2014 Foresters is designed to be maintained by professionals, rely on the owner’s manual for exact intervals and contact a dealer for any level checks beyond basic visual checks of the transmission area (for leaks or damaged hoses). Attempting to diagnose or refill without the appropriate tool can lead to damage or void warranties.
Fluid type, maintenance intervals, and signs of trouble
Key details to keep in mind
To keep a 2014 Forester’s transmission healthy, adhere to Subaru’s recommended CVT fluid specifications and maintenance intervals, which vary by market and driving conditions. Always use the fluid specified for your model year and region, and consult the manual for the exact interval recommendations. Watch for symptoms like slipping, unusual noises, or warning lights, and seek service promptly if they occur.
In summary, whether you have a dipstick or a sealed CVT, the safest approach is to follow the owner’s manual, use the correct Subaru CVT fluid, and rely on a trained technician for anything beyond basic checks. Regular maintenance helps extend the life of the transmission and reduces the risk of unexpected failures.
Summary
For many 2014 Subaru Forester owners, checking transmission fluid is not a DIY task due to the sealed CVT design. If you do have a dipstick, check with the engine warm, in Park, on level ground, and read the hot range. If your vehicle uses the sealed CVT, rely on Subaru’s maintenance schedule and a qualified technician for fluid service and level checks. Always use the fluid specified by Subaru and monitor for signs of transmission trouble, addressing them promptly to protect the transmission’s longevity.
Can low transmission fluid cause stuttering?
If shuddering occurs primarily between 30-45 mph, this suggests torque converter problems related to low fluid levels. This specific speed range often reveals transmission issues that might not be noticeable at other speeds.
Does a Subaru CVT transmission have a dipstick?
Unlike traditional automatic transmissions, most Subaru CVTs don't have a dipstick for checking fluid levels. The process typically involves: Warming up the transmission to operating temperature. Parking on a level surface.
What are signs of low transmission fluid?
If your gears are slipping, it's a clear sign your car's running low on transmission fluid. When experiencing sudden up and down shifts, high RPMs right before shifting, or erratic shifting, seek assistance from your local service center to prevent your transmission from overheating or becoming damaged.

Transmission Fluid: FAQs
A sealed transmission is used to limit the amount of wasted transmission fluid, but just like any vehicle it will eventually need to be replaced. Since this is sealed, there's no dipstick to measure the fluid level, so you can count on our service team to check it for you to avoid any issues.
