727 noise from Reverse to Neutral and 3rd to Neutral when cold.

I recently had a 727 built with a Manual FWD TCI VB and I get a light grinding noise when putting into N from reverse. This is right after I start car and transmission is not warmed up. There is no noise when it is at operating temperature 100 to 150. It shifts great. Also noticed when I first start engine it does not engage into R unless I let to run for 1 min or so. I have a TCI shifter and did my best to make sure cable is engaging gears correct. Coverter is a 3000 Hughes.
