How often should Mazda 3 transmission filter be replaced?

I have a 2005 Mazda 3 A/T, currently at 78k miles. I asked Mazda technician regarding the transmission filter and I was told that it does not need replacement. Neither the manual book make any mention about replacing it. But I do know that there is a filter inside the transmission oil pan. Can someone tell me if this is true? Thanks...|||Almost all modern cars with automatic transmissions never need the trans fluid replaced of the filter cleaned or replaced. Remember unlike the engine oil which is exposed to combustion by products, a modern trans mission is a sealed system and dirt can not make it into the fluid.|||Mazda 3 tends to be pretty harsh on the transmission. If you notice that by 30K miles the transmission fluid is brown like motor oil, instead of red or pink. On Mazda 3 a transmission flush is recommended. Being on the Mazda3forums the guys that did transmission flush have longest trans. life.
