shifter vibrating in upper rpm's
For some reason when im driving fast and my car hits the upper rpm's i start getting this vibrating noise coming from my shifter...i still have the stock auto shifter. and although i have a new tranny in there it was still doing it before but now its worse...any suggestions?

Re: shifter vibrating in upper rpm's
polys are stiffer and therefore cause more vibrations. I m trying to think, mine might rattle but idk

Re: shifter vibrating in upper rpm's
ok, but you need to spot match the location, kinda like balancing a tire. So, when yuo remove a drive shaft, you need to mark the yoke ends and the out put shaft and diff so your still in balance when you put it all back together.

Re: shifter vibrating in upper rpm's

Re: shifter vibrating in upper rpm's
