    only way of fixing that noise is by putting polyurethane bushings..or tranny mounts ..but never heard of that ..hhmm

    dont shift it into 2nd when driving...its a pain on the whole tranny ect. just keep it in 3rd when you want to race...when in third and you shift you have use of 3 clutch packs i believe compared to 1-2(dont quote me on the numbers) 1 & 2 are for towing and not recomended for constant driving unless you get your self a shift kit/built tranny

    try the additive, if not i would think your gear might be screwed.
