My 1998 ford taurus se drove fine yesterday. I get up to go to work and it starts fine but when I put it into reverse it didn't catch like it should. It stayed in N. I went through all the gears and they all were nuetral. I pushed the car no problem in reverse. The fluid is red and not burnt at all and it runs fine. I shifted the car by the tr sensor andf it moved in the dash but still no gear. Please help!

That would be the sign of a dead pump or a totally failed line pressure pressure solenoid. However, that would normally set a trouble code.
