just installed a ltw flywheel over the weekend. probably one of the best performance mods i've done to date but holy freakin noise! lol. its not even a super light one either, weighs about 15lbs. i couldn't imagine what one of those sub 10lb ones sound like. anyway i changed the tranny fluid at the same time per uuc's recommendation except i couldn't find redline 75w140ns so i used 1qt amsoil 75w140 and topped it off with the fluid i previously had in there which i recently changed instead of the d4atf as i figured this would be heavier, either mtflt2 or rp synchromax, can't remember. with the a/c off if i bring the idle up a bit it pretty much goes away, but with the ac on even at 1k rpm its still there. i have a modified sw file on the way with the idle bumped up so that will help a bit with the loads off. has anyone had any luck with any other fluid combinations etc to reduce the noise?
