If no lights came on, chances are it isn't electrical. Check to make sure the fluid is clean and full. If it is, you need to have fluid pressure checked. The converter or front pump may be bad.

if it was the torque converter that crack or failed, shouldn't there be fluid leaking out.

No... They can come apart internally.
