Hi I just completely tore down my 82 Murray to sand it and repaint. Well I pulled the engine off too, and I didn't know there was a hole in the top to the tranny. Anyways when the trans fluid came out it smells sweet, almost like mouth wash or fruit juice. Obviously I want to change that. Does anyone know what I'm supposed to replace with. The engine is stamped e50 on the bottom It's a puch.
