Train Your Transmission: Guide to DIY Transmission Fluid Replacement


From the actual purchase and cost of gasoline to the various tasks to clean and maintain your vehicle, it is easy to see the stressful nature of owning and operating a car, truck, or SUV. Unfortunately, you may not be placing enough maintenance into your vehicle's transmission. Considering it is an imperative part of your vehicle's operation and value, proper maintenance on the transmission is essential to your vehicle's lifespan.

Use this guide to understand the transmission and learn the best techniques to keep it in proper working condition.

Transmission Fluid 101

If you notice the following issues when driving your vehicle, you may have a transmission problem:

  • Rough shifting
  • Slipping transmission
  • Loud clicking, grinding, or popping while shifting

While surprising to hear, these issues may be a sign that your transmission fluid needs to be replaced. To inspect the quality of your fluid, check the transmission fluid dipstick. If the liquid seems dark or discolored, you need to change your transmission fluid immediately.

Since an estimated 9 out of every 10 transmission failures stem from fluid problems, ensuring the transmission fluid is full and clean is key to protecting your investment.


Hiring an auto repair technician to change your transmission fluid is wise, but you can complete the task on your own. Use the following steps to replace your transmission fluid at home:

  1. Line the surface under your vehicle with old newspapers or cardboard. Place a drip pan directly under the reservoir hole of your transmission fluid. This will prevent fluids from staining your garage floor or driveway.
  2. Use a wrench to undo the bolts on the cover of your transmission pan. Work slowly so the fluid does not flow too quickly into the drip pan. Use a cloth to soak up any spilled fluid. Ensure all fluid has drained from the reservoir into the pan.
  3. Remove the transmission filter and O-ring since they will also need to be replaced.
  4. Install your new filter and O-ring tightly. Secure in place with a layer of grease.
  5. Reattach the transmission pan using your wrench and secure in place.
  6. Go to the top of your vehicle to refill the transmission fluid. Most vehicles require 4 quarts of transmission fluid, but consult your owner's manual for the exact amount of fluid your vehicle requires. For the safest replacement of fluid, add a half quart at a time.
  7. Start the vehicle's engine and allow to idle for a few minutes. Check the dipstick to ensure the fluid level is full.

Maintaining your transmission is necessary and protects your vehicle's value and operation. Using this guide, you can easily change your transmission fluid to ensure your vehicle runs efficiently and smoothly. For more insight or assistance, contact repair shops like Soundside Automotive.
