Transmission Cooler Recommendation for a 2015 Toyota Tacoma, Is Additional Fluid Required

Question:

I have a 2015 Tacoma 2.7L 4cyl. I am going to install # D13503 cooler as recommended. My question is, Do I have to add any fluid to make up for the empty void by adding the cooler and if so what type? Thanks!

Helpful Expert Reply:

When you install a supplemental transmission cooler you will need to add fluid because, like you said, the cooler holds a bit of fluid. Also, because you tend to lose a bit of fluid during the install process.

To determine what kind of fluid you would need to use you can check your owner's manual. Or, if you go to an auto parts store they can look it up for your. From the research I did it looks like you will need to use Toyota ATV WS but you will need to verify this.
