shift kit
the part about flushing the transmission - seems to me that if you are trying to correct a problem by flushing it, you will create a larger problem. however, if you are simply maintaining a perfectly functioning transmission - it's one of the best things you can do. my car had 45k on it when i got it - i flushed the trans fluid, added a transgo "full race/high stall (3 washers)" shift kit, b&m deep pan, and 4k stall - drove the ever loving hell out of it for 20k miles, then sold it shifting as good as the day i got it. i changed the fluid twice within that 20k of abuse - once for the converter, and once to repair my broken tailcone...it worked perfectly.
