Sorry bud, no help here. Thought of a couple of questions, full of fluid? The correct type of fluid?

You have me stumped also. It "sounds" like a low fluid issue or maybe even a torque converter. My parents car had the same problem but with 1-2 and it ended up being the converter. There is a chance you could have gotten a bad one, converters can be a funny thing.
