Repair & Maintenance trx300fw no 5th gear ? June 22, 2015 I have a 300fw that shifts fine from 1st throuh 4th but when you shift to 5th it is like you are in neutral. Any ideas of what the problem is and how hard will it be to fix? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
