The costs to rebuild a transmission varies based on the location of the vehicle. Most repair shops charge anywhere from $50-75 an hour for labor. The average price of a transmission rebuild is approximately 900$.
My 1998 accord V6 doesn't have a transmission filter.....I know that the 1998 through 2002 generation models are the same, so my guess would be that there isn't one. It does have a strainer inside the transmission that is permanent.
