i had switch to Gm synchromesh fm...i bought my car new..now is got 12k on it..so i been using gm s fm for maybe 5k...at first it was all smooth out..but after a while i still felt a lil bit notchy..but still better than before and at higher revs shift is smoother than lower..but i heard honda came out w/ some new mtf..i don't know about those...

 

Where can you get the GM Syncro mesh I didn't find it at my local auto shop or autozone or honda dealer???!@?!

 

I purchased mine at my local GM dealer. It fixed my issue for now and hopefully forever. Good luck

 

mmm my 3rd gear grinds only after redlining 2nd.. would it be the same problem?

 

ya, my problem happens weather i shift at 2-9k, enless i double clutch

 

I have the same problem, its pretty annoying and feels like I'm doing more damage everytime. I need to try that Syncromesh also.
