I installed a B&M transmission cooler on a '06 tacoma and found out there is no dipstick or fill port in the engine compartment to "top off" the system after the install. I spent a couple of hours with Google to find the information online from the Toyota manual. I have attached the PDF files showing how to check the fluid level and the link to the entire manual.

The B&M cooler installed easily in an hour and I took part of that time to make a custom bracket (not necessary, but looks nice) I probably lost less than 2 oz of fluid during the install. Also, the return line is the bottom line out of the radiator. You need to get a 3/8" fitting to butt the lines togeather, B&M does not include that part.
