If you’re considering adding Automatic Transmission Fluid (ATF) to your engine oil, you’re not alone. Many Chevy owners are curious about this practice, especially when it comes to troubleshooting potential issues with transmission performance or simply enhancing the overall functionality of their vehicles. In this post, we’ll dive into the reasons behind adding ATF to engine oil and explore how it may affect your Chevy.

What is ATF?

Automatic Transmission Fluid (ATF) is a specialized fluid used in vehicles with automatic transmissions. It plays crucial roles, including lubricating the transmission’s components, providing hydraulic pressure for shifting gears, and maintaining optimal operating temperatures.

Why Consider Adding ATF to Engine Oil?

  1. Cleaning Agent: ATF contains detergents and additives that can help clean engine components, potentially removing sludge and deposits that have built up over time.
  2. Improving Lubrication: Some enthusiasts report that adding a small amount of ATF to engine oil can enhance the lubrication properties, keeping engine parts functioning smoothly.
  3. Troubleshooting Transmission Issues: If you’re experiencing issues with shifting or transmission response, adding ATF to the engine may help, although it’s important to note that it shouldn’t replace proper transmission fluid.

How to Add ATF to Engine Oil

If you decide to give this a try, here’s a step-by-step on how to do it:

  1. Check Your Vehicle’s Manual: Before making any modifications, always refer to your owner’s manual for recommendations specific to your Chevy model.
  2. Gather Your Materials: You’ll need the appropriate ATF for your vehicle and a funnel for easy pouring.
  3. Drain the Engine Oil: If you’re doing a complete oil change, drain the old oil completely. If you want to add ATF without changing the oil, just proceed to the next step.
  4. Add ATF: Pour in a small amount, usually no more than a quart for a full engine oil change. If you’re just topping off, consider starting with half a quart.
  5. Monitor Performance: After adding ATF, drive your Chevy and monitor any changes in performance or oil pressure.

Precautions

  • Don’t Overdo It: Adding too much ATF can lead to excessive foaming and compromise lubrication.
  • Monitor for Changes: Keep an eye out for any unusual engine noises, oil pressure changes, or other performance irregularities after adding ATF.
  • Consult with a Mechanic: If you’re unsure, getting a second opinion from a professional mechanic might be a good idea.

Conclusion

While the idea of adding ATF to engine oil might seem unconventional, many Chevy enthusiasts do it as a part of maintenance or troubleshooting. Just remember, moderation is key, and it’s always best to address any serious transmission issues directly with the appropriate fluids and maintenance.

That sounds like solid advice. I’m planning a DIY oil change; should I do a full oil flush first?

A flush is often recommended before switching oil types. It ensures that any residues or incompatible fluids are cleared out, which can help your engine run smoothly afterward.
