Can't find it GRIND IT! LOL... that trucks tranny was way overworked with tires that size and an engine that doesn't produce very good low end torque... Tranny had to work hard and ended up blowing it's brains out b/c the owner spend all his money on the tires and engine mods and didn't think about the poor little 1/2 ton tranny that wasn't made for that kind of abuse...
