Grinding shifts

renns · 02-19-2008, 01:31 PM

Just installed a TiC/Kartboy SS and bushings, and I'm grinding my shifts into second on high RPM shifts now. Not huge or violent grinds, just a little grinding sound. I'm not forcing the gearstick in, just a quick snap of the wrist and it's into second. Even if I hold the clutch in and put it into gear, it still chirps the gears.

Is this horrible for the gears if I do it every once in awhile? Do I just need to break the shifter in?

I definately didn't notice this before when I had the stock bushings. I just want to make sure this is the increased NVH that comes along with the bushings and not installation error.

It is not good for the syncros. I wonder if the grind was already there and the bushings did not allow you to detect it...or...you have the shifter hooked up incorrectly. Does it happen 100% of the time or just sometimes?

make sure all the fittings are tight, and in the right place. You're bushings under the car might be to tight. Good luck!

this happens to me too. Only in second though. Sometimes when the car isnt warm, i have a hard time getting it into 1st and 2nd. And when I get it into second i hear a grind while putting it into 2nd.
