i dont really follow what u wrote. u r asking about a transmission fluid change? there r 2 forms of service. u can ask for just the transmission fluid change. that would remove 1/3 of the current fluid by draining it out, leaving what is in the torque converter alone. the other hooks the lines up to a machine and removes all of the fluid known as a flush. u can choose either one. the latter is more expensive.

there is a debate about using just honda transmission fluid. i did use only honda tranny fluid had my tranny serviced on time at a dealer, flushed the last time and the tranny went out in less then 2 wks. i now have non honda fluid with a conditioner in it. have changed it 1x with no problems at all with the used tranny i had installed in jan 05.
