I really wouldhave no idea as i'm a mechanic and don't look for these sites for that. however what kind of truck is it I've neverheard of bell is it a chevy, gmc ford or international ? isn't bell a dump box manufacturer. Like I said call a trans shop they may work on medium duty trucks and i'd bet it's an Allison trans in it.
