Fluid is just at the bottom line when cold, right beneath the top line when warm.

The flaring started without warning. First, there were times when it wouldn't shift from second to third -- it would just get hung up and accelerate. I refreshed the filter and fluid which seemed to help with that problem, but then the flaring began. Like I said, I replaced the K1 spring which reduced the flaring without eliminating it completely.

Thoughts?
