Was driving down the freeway and within one mile of feeling the transmission start to slip and motor rpm's increasing, I had lost all gear's and was unable to continue driving my vehicle any further. It had to been towed home. There was no warning sign's that the transmission was going to fail nor did any warning lights appear in the dashboard.

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.
