I have been doing some research on the old 3406B CAT motor & I ran across some interesting info on some guys running tranny fluid in their tanks. Something along the lines of 1qt. of tranny fluid per 100 gallons of fuel - has to do with keeping injectors clean or for some other reasons for their old engine. Has anyone heard of this? It sounds like something I am interested in doing for my 3406B with almost 300,000 on it.
