2025 3500 cummins zf8 oil leak

[woodrow]

I found this oil residue under my 25 ram cummins when changing my oil. It has 8k miles on it, has anyone else had this issue

It’s not trans oil it’s the protective coating that they put on the flywheel. It gets hot and melts off. Use some brake cleaner it will subside in time.

Wipe it off, and keep an eye on it. None of my vehicles ever did that. But, not to throw you into a paranoid episode, I have seen leaky rear main seals do that, as well as leaky transmissions. Use a white paper towel, wipe the fluid up, give it a look and a sniff, to see is it is engine oil or transmission fluid.
