If you are stuck on Type F Walmart generall always has it.

As for the Transynd it keeps my stuff much cooler than anything else I have ever used. And if you run a car on a stop they tend to put some heat in the trans. If oyu want to run B&M colored type F go for it. Ill stick with what has worked best for me. And I have been through a lot of cars and combos over the years.
