Meanwhile, ZF - who manufactures these transmissions - says they should be serviced around 60,000 miles / 100,000 km. I personally don't buy what BMW claims - I don't believe there is any "lifetime fluid" out there on the market. And therefore, here I am, servicing the ZF8 Transmission with fresh fluid and new pan filter change on my 2020 BMW G20 M340i xDrive. Since my transmission is tuned with xHP, I have this performed earlier than the recommended service interval. Note that if you have a mild-hybrid model, the pan filter has a different design than the one I showcase, due to the placement of the addition start-stop filter that doesn't exist on the non-mild-hybrid models. As ZF8 Transmissions are broadly used in modern vehicles, the procedures taken to service them are vastly similar to what I've showcased with other makes and models that use ZF8 as their transmissions. By no means am I a professional mechanic, I am also trying to learn as I go, and to learn from my mistakes. If you do have any input or question, please feel free to drop them in the comments. I will try to address them as best as I can. #m340 #b58 #zf8 00:00 Intro 00:53 Lift the Car on All Four Corners (to Be Leveled to the Ground) 01:43 Removing Undercarriage Splash Shield 05:48 Main Work Starts: Cracking Open the Fill Plug 05:59 Removing Drain Plug 08:26 Removing the Transmission Fluid Pan - 13x T40 Bolts 09:11 Cleaning the Mating Surface of Pan Gasket & Transmission 09:37 Visual Comparison Between Old & New Transmission Pan FIlter 11:23 Installing the New Transmission Pan Filter 11:58 Torquing all 13x T40 Bolts to 10 Nm 12:30 Measuring How Much Fluid We Have Drained 13:20 Cold-Filling Till Overflows 13:50 Monitoring the Transmission Fluid Temp 14:46 ZF8 Filling Procedures Overview - Start to Finish 15:51 Start the Engine Till It Reaches 30C - 50C 17:36 Rev Engine to 2000 RPM for 30 seconds to Fill Torque Converter 18:22 Shift Around 19:21 Warm-Filling Till Overflows 20:32 Torquing Fill Plug to 35 Nm 20:43 Cleaning Up & Checking for Leaks 21:15 Reinstalling Undercarriage Splash Shield 21:57 Conclusion & Keynotes -------------------- Disclaimer: The information provided in this video is for general informational purposes only and is not intended as professional advice.
