So I ordered a transmission off eBay with a quaife lsd in it but the guy failed to tell me that spot where the clutch slave mounts was broken off… so I decided to swap all the guts into a spare case I had laying around. I just fired up the car and tried to get it to move and first gear just grinds and pops out all other gears seem to go in fine and the tires spin… did I get sent a bad first gear or did I screw up the install? Any guidance would be appreciated. Thanks in advance.
