Will the motor and transmission for a 1999 crown victoria work in a 1993 grand marquis?

It should. I know it will physically fit, but weather the electrical controls are the same, I am not sure. If you switch the electronics off of the 99 and place them onto the 2000, you should be good. The only thing I would worry about would be the transmission. If you go to www.car-part.com and search for the part you are using. The site has a built in Hollander interchange and should list if one is compatible with the other. If it isn't listed, then there must be a difference.

Yes it can, there are many parts around for a rebuild, even upgrade some parts, you can also rebuild your transmission too, even change gears. But you can also find used low mile engines around as well as a replacement , These are modular engines , Grand Marquis will work as well

MOST INTERCEPTER CARS, MEAN THEY HAVE AN ADDED GEAR IN THE TRANSMISSION! WHAT YOU'LL BE DOING IS GOING TO A TRANSMISSION WITHOUT THAT EXTRA GEAR! TO ANSWER YOUR QUESTION: YES YOU CAN REPLACE IT WITH A REGULAR TRANSMISSION! YOU JUST WON'T BE ABLE TO CHASE BURGLARS! HAHA
