The filters now are prettymuch only for catastriphic failure. Transmission should be powerflushed to get all the fluid out/clean.

I have about 45K on the clock and use it for towing. The fluid is still red and from what I see on the GM TSB, they do not recommend full flush unless there was a catastrophic failure. I plan on using a 12v oil pump to suck the pan dry, put fresh Dex VI in, run the vehicle for a short time and than drop the pan, change the filter and refill... I know there is alot of debate on this but why would GM suggest changing the filter at 50K if it is used for towing? My own feeling is that it does not make sense not to perform a service gm suggests and do one on place of it that they do not. Am I overlooking something?
