Transmission oil

Yamalube 10W30 is the oil recommended for a Blaster.

Belray 80 is ok, Auto Trans fluid type F, is ok.

10W30 engine oil with no friction modifiers is ok, as well as oil designed for wet clutches.
 
I use Amsoil Type F racing transmission fluid.

I had a 1.5 ton Ford Powerstroke diesel with a 5 speed manual transmission. The factory called for Type F automatic transmission fluid in the trans. sh*t must work good...
