[Help] Transmission Locked

My grandmother was driving on the freeway when her transmission decided that it's time had come. The car is a 1993 Honda Accord front wheel drive manual. The issues is that it cannot drive or be pushed, we moved it 10 feet further into the shoulder by pushing but it was done by sliding the tires across the pavement. We have a truck to move it but no trailer, what do we need to rent and how do we get it on? Thanks for any help.
