The 91 tranny requires a TV Cable to control line pressure. The computer is also going to complain about the 93 tranny missing and it will set the Check Engine Light. Some states will not let you pass a smog test if the light is on. A new chip will be needed to turn the light off.

I believe that they are the same size. The 93 is a 4l60E and the 91 is a 4l60 (also known as 700R4).

If you do the TV Cable it should work. Take some measurements to make sure that are the same length.
