I've seen conflicting info as I'm trying to buy a replacement A/T filter and gasket. Some sites say they aren't a direct match, some say they are. When I look up the part number of the transmission is seems to only have a single A/T used (4R70W). Just wanted a second opinion of people who have changed them over before.

Also, how many quarts of A/T fluid will I need to replace once I drain the A/T to replace the filter?
