If the rattle ONLY happens during the transition to direct drive, then that is most likely the DD clutch slipping a bit when engaging--somewhat normal on trans with old hardened clutch plates not used much. When it comes time for shift point, let up on accelerator while it shifts and if noise not present or greatly diminished, that is problem and some driving, possibly use of the trick shift fluid or in worst case, new clutch disk will probably make it go away. If the rattle is there all the time, then I'd check for something loose.
