Re: 2005 Ford Taurus Transmission ?
A '92 to a '05 won't mate up correctly, as the chassis are different, along with the mounting points, bellhousing, etc.
As S6 mentioned above, the shift linkage is the most probable culprit. I haven't checked on my own Taurus, but you should be able to adjust it along side the transmission, under the vehicle. A repair manual will help if you plan to do it yourself, and get/hire a friend for a couple hours.
If you're one who likes to throw the gear selector into gear while the vehicle is still moving, ie, backing out of a driveway still rolling when you move the selector from R to D, then as mentioned, you more than likely have a linkage problem. If the linkage is the culprit, be sure to monitor your own driving habits to make sure you don't strain the transmission, in any way, more than necessary to get the longest life out of the unit.
