Adding Transmission Fluid After Installing Transmission Cooler on 2013 Toyota Tacoma 2.7L
Question:
Hello, I am looking at installing a transmission cooler on my 2013 Toyota Tacoma 2.7 4 cylinder truck. Will I need to add more transmission fluid after install even if no fluid leaks out?

Expert Reply:
Because adding an auxiliary transmission cooler and additional hose length extends the overall cooling system, it is likely that you will need to add a bit more transmission fluid even if no fluid is lost during installation. Often adding a cooler requires adding somewhere between 1/2 pink up to 1 quart of additional fluid.
It is a good idea to add fluid a little at a time, testing the dip stick as you go along, until the system no longer indicates it is low on fluid.
If you have room for it, the Derale Transmission Cooler # D13503 is a great, large size cooler for your Tacoma. This cooler measures 11 inches W x 8-3/4 inches T x 7/8 inches D.
I have attached a link to all of the transmission coolers for your Tacoma with 2.7L I4 engine.
