beefin up the tranni
IIRC, it's a lever that applies the tension to the bands during shifting. You normally replace it with a billet one. Also a good idea to replace the accumulator piston. The stock one is plastic...
I called a local DTT dealer/builder, and talked to him. He built my trans, told me about all of those parts. I ended up getting the accumulator piston, the apply lever, upgraded clutch packs...all that good stuff.
