X2. changing the transmission fluid is like changinging the engine oil, both have a filter to change. it is there for a reason.
Just be careful when replacing the pan and gasket that you don`t over tighten the bolts. It is in inch lbs, not very much. tighten too much and you will have leaks.
drain the torque converter also.
this is sort of like taking a shower, and not changing your shorts.
