2018 ex 300 power valve
 

Hey guys! I had my 2018 ec 300 rebuilt and ever since then my tranny oil gets black extremely quik. It seems to me it leaks down from the power valve rod in to the clutch side and Dirty?s the oil. Are there not any seals on the power valve to keep it from doing this?

Thanks
Steve

Thats common in all architecture.

I'd suspect clutch plates. Could they be aftermarket or just trashed and slipping.

You likely didnt use a sealed or shielded bearing. You don?t want exhaust gases to flow inside the right side pv cover
