i know the tranny from the mr2 works in the celica, so i would assume it is compatible the other way as well, but the celica transmission has a much more conservative gearing than the mr2 tranny. you can disable the awd by putting a cap over the output shaft that goes to the rear wheels, but you will lose a lot of power with that output just spinning, so if you have 2WD, use a 2WD tranny, it just works better
