Torque Converter Guidence?

Alright.

The tag on the diff says 2.76 and the motor idles at about 550-600 ish.

The engine sounds... more burbly than the old motor? But the old one was pretty beat. Sounds like a beast up around 5k with no valve issues I could hear and it didn't 'splode :P. I've never taken it higher because I'm worried about the transmission. (And I was actually worried just winding it that far out)

If it helps, I could make an audio recording with a nice mic.
