3 companies make a Transmission filter kit available for the A5S 390R Automatic Transmission from what I've found : Genuine BMW, Elring, Febi.
I've heard the Elring kit is complete in terms of what is needed to be replaced when the filter is being serviced, but the filter itself is not adequate in comparison to the one that comes in the vehicle from the factory. Does anyone know if thats true?
Assuming that the Elring kit is not the best replacement option, would the Febi kit be worth buying? I've heard nothing about this particular kit but noticed its priced closer to the OEM filter kit price than the Elring kit.
I plan on tackling the ATF Fluid replacement in the next week and want to purchase the most sufficient filter kit for the transmission. As much as its nice to save a few extra dollars, I dont want the life of my transmission compromised due to that. Can anyone chime in?
