check this out... im finishing a resto on a 73 cuda im now working out the bugs. this bug has got me super stumped. heres the issue. its a 23 spline trans. it shifts fine when turned off. but when started it wont shift. so i pulled the universal and when started it shifts fine with out the universal in. the yoke fits nice and slides nice into place. im wondering if the yoke is too far in it might be jamming something. but i dont beleive thats the problem since i tried lifting the car and on the ground while trying to get it to work properly. any help is highly appreciated
