transgo drill plate used on wrong year of trans

Hello,

After installing my TF-1 kit my car feels like it is binding/fighting itself in forward gears, wont move, has reverse.

So i reviewed my instructions on my TF-1 kit and found that i used the drill plate and spacer provided on my 73 727, in the instructions it says 1977 and up. Could this be my problem? Any help is appriciated. Thanks folks.
