Hello and welcome to JustAnswer!

If the transmission doesn't engage and the engine revs as if it were in neutral then the issue is internal in the trans, the rear differential, or possibly very low fluid level.

Has the fluid level been checked?
With the trans in park are you able to push the vehicle or do you feel a hard mechanical lock?
