I did a transmission swap. I used an 89 dodge truck 727 transmission in my 66 Plymouth Fury III four door. I got everything bolted up, fluid in, and everything looked good. Start it up and it is making a noise like something is grinding? Plus I can't shift it into first or second and it acts like it don't have neutral like the linkage isn't right. Help!

 

Start by checking the flex plate bolts and tin.. Re check the shifter linkage
