MB brand filter and connector aren’t expensive even at 2-3x the price of aftermarket. That’s not where I’d save a few bucks. Get them from a reputable seller such as Pelican, sponsors of this site or a MB dealer. Lots of claimed genuine MB parts sellers on Amazon and eBay aren’t. Symptoms - connectors leak within a couple of months, poor fitting filters allow air into the pump starving the transmission of fluid. Look up transmission whining and dropping out of gear without CEL.

Oddly, I haven’t read of aftermarket conductor plates having poor fit or short life.
