Question!
When I removed my factory transmission cooler, I found this random black O-ring gasket.
There's already a green O-ring gasket in the OEM female fitting. And then there's also a black O-ring gasket that just fell out.
I have no idea where it goes because it's too big to seat anywhere. I tried to seat it at the bottom, but it's just too big and flops around sideways.
There's no other grooves in the fitting besides the groove for the green o-ring.
So I'm a little stumped. Can I go on without it?
