Which transmission.

The new fluids are not necessary.
Personally I run type F and have in every 904 or 727 as well as my 42rh.
But you can run whatever makes you happy.
Thanks. I'm assuming it has Dextron in it as it's a one owner car and didn't want to mix fluids. The owners manual says 16 pints capacity. I'm guessing that's the amount it takes when refilling it after a filter change?
