just a question does anyone elses gears grind when shifting at high revs like 5500 or sumthing is there anything that can be done to stop this
My car does this going into 3rd.
Could be worn mounts, syncros, shifter bushings, not enough fluid, etc.
My JDM YS1 does this as well at high rpms. Many people say to try GM Syncromesh, so first i would check your fluid level, and if its low and/or old, switch it out.
