I am working on doing the twin stick mod on my 205. I put the rail for the front output in neutral. Then when I try to pull the rail I ground all the way out which would be either (rear wheel drive low or high), it won't lock into gear. If I pull on it hard, it will move a little, and the input and rear outputs move together, as soon as I stop pulling on the rail it slips out of gear. Any ideas? Thanks!
