Which transmission.

Thanks! I'm was planning on using either Dextron Vl or ATF4+4. I'm only replacing the amount that comes out of the pan when it's dropped. Would Dextron Vl be better? Thanks.

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.
