Cost of Transmission Fluid Flush
 

I was wondering how much I should expect to pay for a transmission
fluid flush (not a drain). I'm talking about when they completely
remove all the old fluid and replace it with new fluid, as opposed to
just draining and re-filling. I've got a 1998 Honda Accord LX 4-cyc
with 72K miles.

I was quoted a price of $220 from a mechanic I trust, but just wanted
to make sure.
