Recommendations for trans fluid??

904 trans , manual reverse valve body, extra 2 quarts deep pan , 3500 converter, huge cooler.
Reasonably priced!!
O’Reilly, Advance or Autozonk store brand Dex/Merc. Stuff is red, smells like, and has that feel of tranny fluid! Works just like it should. I’d spend my time wondering about ensuring no pan gasket, shift shaft seal or front pump bushing leaks. Well, I do at least! :thumbsup:
