Anybody use this in there trannies??

 

Exactly why would we?

 

I'm talking about the atf that they make.
not motor oil

 

ok................

 

Not many have run it in their trannies. Royal Purple hasn't shown to be a very good oil according to the Oil analysis spreadsheet located at the top of this page. Amsoil and Mobil 1 ATF's have a proven track record and good analysis results.
