2 Flush or not 2 Flush ?

There is this hot debate regarding the 406 Gearbox - ZF 4HP20.

One school of though felt that flushing will improve gearbox functionalities as all the smug, slug and "impurities" will be flushed out and thus will keep the GB in optimum state.

Another school of thought think otherwise. Flushing will actually cause more harm than good. This is due to the Gearbox ATF filter also known as "Main Pick Up" is made of materials that filters very fine debris. It's so fine that flushing would not help as it will actually clog the filter faster.

here is the picture of the ATF Filter.

Another angle.

The Filter material.


Now, the questions is 2 Flush or not 2 Flush ..??

The choice is yours .....
