Better than the OEM tool
Better than the OEM tool kit. Recommend for anyone that regularly services Mercedes 9G-tronic automatic transmissions. Only thing that's missing is the smaller filling adaptor for the hybrid models.

Mercedes oil tool
The thread on the filling part was full of melted plastic. And one lug was broke off. Ended up throwing it in the bin.

Great quality
Good quality, well machined. Beats a my plastic version hands down. If you service or own a merc with a 9g gearbox, this is a must have.

Absolute Must-Have for the DIY'erI deI
I decided that I wanted to start doing all of maintenance that I could on my Mercedes. After scrolling through all of the YouTube tutorials on how to do the transmission and transfer case fluid changes, you HAVE to have these tools otherwise you can't do it. They worked perfectly and were very simple to use. If you want to start doing it yourself, then you need to have this on hand. Performed as expected.
