Still have an oil leak after replacing valve cover gasket oil pan gasket and rear main seal

Its definitely trans fluid. I just haven’t figured out the source. It is all over the top of the transmission, but virtually no dripping on the ground. I’ll check the cooler lines. Thanks for the tip.

Exactly what mine was doing. I think the issue is that the fluid only flows with the engine running....therefore not much leaks when parked. When driving, the leaking fluid gets blown all over the place. Crawl underneath with the engine running....I'll bet you find the source. Mine was leaking at the crimped fitting that joins the hard line from the trans with the soft line from the radiator.

Try Valvoline Maxlife my friend!
