This will set your tension a little tighter on the cable and allow for the clutch to better disengage.
How ever if this does not rectify your grinding problem , then I suggest you contact who ever rebuilt the trans. Im assuming this is a T-45 trans? Misplacing 1 little spacer in this trans can cause all kinds of shifting problems. There is 0 tolerance for mistakes on these trans ( or any trans ) when rebuilding them. I recently just opened up a t45 that was having trouble with 5th and reverse, and also the trans was clunking between gears. I found that who ever pulled it apart last left out a very thin spacer behind the input shaft bearing cap. Just that .030" spacer caused the whole assembly to be off , and caused a lot of slop in the main shaft and input shaft.
Well DELK PERFORMANCE a mustang performance shop did it. But I have stage 2 clutch, and stage 2 tyranny set up. But haven't put an aftermarket clutch cable in. Ad Ita got 200,xxx miles on it haha
