700r4 rattle under load

iv had 2 thirdgens both had 700r4's and 305's and both have had a transmission rattle under load each gear is worse than the next mostly 4th gear does anyone know what causes this and more importantly how to fix it, i have tried adjusting the tv cable and i have firmed up my shifts.

if im cruising in 4th and start pushing on the gas i get rattle and it doesn't downshift like it should, may have to visit a transmission shop and see what they say.
