I bet it is the front clutch piston having a bad seal. There would be no engagement if the pump was bad.

Does it go into reverse?

You have an internal failure that will rewuire removal and most likely an overhaul.

There are many ports on the trans to check various pressures. You need gauges and a manual to identify each tap point. It will most likely confirm internal failure.
