Transmission Oil Filling Tool Fit for Mercedes Benz 725.0 9-Speed Transmission, Plastic Oil Draining Tool Adapter Kit

Everything worked and fit fine except the tool to turn the valve. Being made of plastic it flexes a lot. The valve in my pan had a little resistance in it, preventing me from smoothly switching between the fill and closed positions. I would recommend getting a more rigid tool for actuating the fill valve on the pan. I believe an 8mm hex key will work. That is likely the route I will go in future fluid changes as this one resulted it me spilling out a small amount more fluid than I should have us to the excessive flex. The plastic tool works great for the rest of the operation. I just suggest pulling out a long stem hex for the final closing.

Do not buy this tool. It is flimsy plastic and the valve selector tool twists before the valve moves so you don't know what position the valve is in. Total junk. I threw it in the trash and ordered a metal one. You get what you pay for. Spend another $10 and get a metal set.
