OK heres the deal I have a 95 GSR with 151,000 miles on it. The other day I started noticing that when I shifting from 2nd to 3rd I got a grinding noise. But it only does it when im going over 4500 RPM anyhting under it doesnt do it anything after it does. I changed the fluid about a year and a half ago using full synthetic 10W30 motor oil. I have been told that it is probabaly the blocker ring going bad. I mean how long should that tranny last?? If anyone has any suggestions please let me know. thanks shwnoff@msn.com
