This stuff is awesome!
This was magic for my transmission. I had a bad shutter. My mechanic told me to try this for my torque converter prior to replacing it. If I had not seen this, I would not have believed it! This stuff is unbelievable! I know it's probably only a patch but it has bought me more time.

2020 Mercedes GLS450
Mercedes 2020 GLS 450 / Transfer Case: Recently didn't routine maintenance on our GLS with 95k miles. Last time was at 50k miles. Front/Rear differentials and transfer case. I was getting the low speed humming on turns after the service. I used MB fluids that were called for from the dealership. The transfer case is Limited Slip, but the differentials are not. I ultimately decided to try this product (I use their HVAC cleaner, and also trans additive in my Ford 10R60). Within 10 miles, the noise and corresponding vibration was completely gone. One bottle into the transfer case with the fresh MB 239.41 gear oil, and it's back to behaving like the day I bought it. Sharing because I don't see any Mercedes reviews.
