How to Change Your Subaru Transmission Fluid - Step by Step Guide

Changing the transmission fluid in your Subaru is a crucial maintenance task that can help ensure your vehicle runs smoothly for years to come. Here’s a comprehensive guide on how to do it yourself!

Why Change Transmission Fluid?

Transmission fluid is vital for lubricating the components inside your transmission, helping it shift gears effectively. Over time, this fluid can break down or become contaminated, which may lead to poor performance or even transmission failure.

When Should You Change the Fluid?

  • Mileage: It’s generally recommended to change your transmission fluid every 30,000 to 60,000 miles, but always check your owner’s manual for specific guidelines for your Subaru model.
  • Color Change: If your transmission fluid is dark brown or has a burnt smell, it’s a sign that it needs to be changed.

What You’ll Need:

  • New transmission fluid (specific to your Subaru model)
  • Transmission filter (if applicable)
  • Socket wrench set
  • Drain pan
  • Funnel
  • Safety gloves

Step-by-Step Guide:

1. Prepare Your Subaru

  • Park your vehicle on a flat surface and turn off the engine.
  • Engage the parking brake for safety.

2. Locate the Transmission Pan

  • Refer to your vehicle’s manual to find the transmission pan. It’s usually located along the bottom of the transmission.

3. Drain the Old Fluid

  • Place the drain pan underneath the transmission pan.
  • Use a socket wrench to remove the bolts securing the pan and carefully detach it. Let the old fluid fully drain.

4. Replace the Filter (if applicable)

  • If your Subaru has a filter, now is the time to replace it. Remove the old filter and install the new one according to the manufacturer’s instructions.

5. Reattach the Transmission Pan

  • Clean the pan and the area around the transmission. Then, reattach the pan securely with the bolts.

6. Fill with New Fluid

  • Locate the dipstick tube for the transmission. Using a funnel, pour the new transmission fluid into the tube until it reaches the appropriate level as indicated by the dipstick.

7. Check for Leaks

  • Start your car and let it run for a few minutes. Shift through the gears while keeping an eye on the transmission pan for any leaks.

8. Dispose of Old Fluid Properly

  • Remember to take the old transmission fluid to a recycling center or an auto parts store that accepts used fluids.

Summary

Changing your Subaru transmission fluid doesn’t have to be a daunting task. With the right tools and a little patience, you can do it yourself and keep your vehicle in great shape!

For older models, like pre-2010, conventional fluid is often recommended. Always check your owner’s manual to be sure!

100% agree! My friend’s manual suggested a specific brand which worked great for her 2012 Subaru.

Don’t forget to consider the climate too! Some fluids perform better in extreme temperatures while others can cause issues.

This is super informative! So, can I use a different brand of synthetic fluid if I can’t find the one that’s recommended?

Yes, but make sure it meets the specifications for your model. Compatibility is key!

I’ve always used Subaru’s branded fluid in my 2020 Forester. Is it worth it, or can I save money with other brands?

It depends! If you’re not experiencing issues, you could try alternatives, but maintaining warranty coverage is crucial.

What about adding additives to the transmission fluid? Any recommendations?

I’ve heard mixed reviews, but if your fluid is starting to look dirty, a flush might be more effective than additives!

This is such a lively discussion! I personally enjoy working on my Subaru, and changing the fluid is always a satisfying task.

So, can anyone clarify if the same fluid is used for both automatic and manual transmissions in Subarus?

Nope! They use two different types. Always double-check to avoid damage.
