Locating and Accessing the Transmission Fluid Dipstick
On the 2015 Subaru Forester, the transmission fluid dipstick is typically located near the back of the engine bay, close to the firewall on the driver’s side. However, the exact location can vary slightly depending on the engine type and transmission model installed. For automatic transmissions, the dipstick is usually marked with a brightly colored handle—commonly yellow or red—to distinguish it from the engine oil dipstick.
Before attempting to check the transmission fluid, ensure the vehicle is parked on a level surface and the engine is running at normal operating temperature. This is crucial because transmission fluid expands when warm, providing an accurate reading of the fluid level and condition.
To access the dipstick:
- Open the hood and secure it with the prop rod.
- Locate the dipstick handle by scanning the rear portion of the engine bay.
- Remove any engine covers or components that obstruct access, if necessary.
- Pull the dipstick out carefully, wiping it clean with a lint-free cloth before reinserting it fully.
Performing these steps carefully prevents contamination and ensures precise measurement.
Checking the Transmission Fluid Level and Condition
After reinserting the dipstick, pull it out again to check the fluid level. The dipstick is usually marked with two indicators:
- “Full” or “Hot” line: Fluid level when the transmission is at operating temperature.
- “Add” or “Cold” line: Minimum fluid level when the transmission is cold.
The fluid level should be within the indicated range when the engine is running and warm. If the fluid is below the minimum mark, it requires topping up to avoid transmission damage.
In addition to level, assessing the fluid condition is vital:
- Color: Healthy transmission fluid is typically a bright red or pink hue. Dark brown or black fluid suggests oxidation and contamination.
- Odor: Burnt smell indicates overheating or potential internal damage.
- Texture: Fluid should be smooth and slippery; gritty or thick fluid signals degradation.
If the fluid appears discolored, smells burnt, or contains particles, a transmission service is recommended.
Recommended Transmission Fluid Type and Quantity
Subaru specifically recommends using their proprietary automatic transmission fluid for the 2015 Forester, often labeled as Subaru ATF or Subaru High-Performance ATF. Using the correct fluid type ensures compatibility with the transmission’s materials and optimal performance.
Below is a summary table of the transmission fluid specifications and approximate quantities for the 2015 Forester:
| Transmission Type | Fluid Type | Capacity (Approximate) |
|---|---|---|
| CVT (Continuously Variable Transmission) | Subaru CVT Fluid (Part Number: SOA868V9220) | 7.4 quarts (7.0 liters) |
| 6-Speed Manual Transmission | API GL-4 75W-90 Gear Oil | 2.8 quarts (2.65 liters) |
Always consult the owner’s manual or a certified Subaru technician to confirm the fluid type and volume before performing any service.
Steps for Adding Transmission Fluid
If the fluid level is low, add the correct transmission fluid cautiously to avoid overfilling. Overfilled transmission fluid can cause foaming, erratic shifting, and damage.
Follow these steps:
- Use a clean funnel to prevent introducing dirt into the transmission.
- Add fluid slowly in small increments, checking the level frequently.
- After each addition, wait a few minutes for the fluid to settle before measuring.
- Ensure the vehicle remains on a level surface and the engine is at operating temperature during the process.
Never use fluids other than those specified by Subaru, as incompatible fluids can degrade transmission components and void warranty coverage.
Safety Precautions and Maintenance Tips
When handling transmission fluid, consider the following safety and maintenance guidelines:
- Wear gloves and eye protection to avoid skin and eye contact.
- Dispose of used transmission fluid properly; do not pour it into drains or onto the ground.
- Regularly inspect the transmission fluid as part of scheduled maintenance, generally every 30,000 to 60,000 miles.
- Address any leaks or transmission performance issues promptly to prevent costly repairs.
Routine checks and proper fluid management extend the lifespan and reliability of the Subaru Forester’s transmission system.
How to Check Transmission Fluid on a 2015 Subaru Forester
Checking the transmission fluid on a 2015 Subaru Forester is essential for maintaining optimal transmission performance and longevity. The process varies slightly depending on whether your Forester is equipped with a CVT (Continuously Variable Transmission) or a conventional automatic transmission. Most 2015 Foresters come with a CVT, which requires specific procedures.
Tools and materials needed:
- Clean rag or paper towels
- Funnel (optional, for adding fluid)
- Subaru-approved CVT transmission fluid
- Jack and jack stands or ramps (if necessary)
- Protective gloves
Step-by-step procedure for CVT fluid check:
- Warm up the vehicle: Start the Forester and allow the engine to reach normal operating temperature by idling for approximately 5 to 10 minutes. The transmission fluid must be warm for an accurate level reading.
- Park on a level surface: Ensure the vehicle is on flat ground, engage the parking brake, and leave the engine running.
- Shift through gears: Slowly move the gear selector through all positions (P, R, N, D) pausing for a few seconds in each to circulate the fluid.
- Locate the transmission fluid check plug: Unlike traditional automatics with a dipstick, the 2015 Forester CVT typically has a transmission fluid check plug on the transmission case. This is often located underneath the vehicle.
- Raise the vehicle if necessary: Use a jack and jack stands or ramps to access the transmission check plug safely.
- Remove the check plug: Carefully remove the check plug using the appropriate tool (commonly a hex or Torx wrench). Be prepared for fluid to possibly drip out if the fluid level is correct.
- Check fluid level: The fluid should be level with the bottom of the check plug hole. If fluid starts to drip out, the level is adequate. If not, additional fluid is required.
- Add fluid if needed: Using a funnel and Subaru-approved CVT fluid, add small amounts through the check plug hole until fluid begins to seep out, indicating the correct level.
- Reinstall the check plug: Clean the plug and sealing surfaces, then reinstall and torque to manufacturer specifications (typically around 29–33 Nm or 22–24 ft-lbs).
Important considerations:
- Do not rely on a dipstick for CVT fluid level, as the 2015 Forester CVT does not have one.
- Always use the Subaru-approved CVT fluid to ensure compatibility and avoid transmission damage.
- Wear gloves and be cautious of hot surfaces and fluid to prevent burns.
- If uncertain or uncomfortable performing this check, consult a professional technician.
| Step | Description | Notes |
|---|---|---|
| Warm Up Vehicle | Idle engine for 5-10 minutes | Ensures accurate fluid temperature |
| Park Level | Place on flat surface, apply parking brake | Prevents inaccurate fluid readings |
| Shift Gears | Cycle through P, R, N, D slowly | Circulates transmission fluid |
| Access Check Plug | Locate and remove plug under vehicle | May require lifting vehicle |
| Check Fluid Level | Fluid should be level with hole bottom | Fluid dripping indicates correct level |
| Add Fluid | Add Subaru CVT fluid if low | Use approved fluid and add slowly |
| Reinstall Check Plug | Torque plug to spec (29–33 Nm) | Prevents leaks and contamination |
