I have a 2004 tsx
Long story short my second and third gear were grinding so I switched out the master cylinder and the slave and put a new clutch in and blood the clutch line and put new tranny fluid in but it still grinds not as bad tho but still grinds does this mean that the synchros are bad??
It's a brand new slave and CMC so I'm guessing it's it's the syncros
Brand new clutch and CMC is all the more reason it should be adjusted for proper travel. Typically after a new clutch install you adjust it before break in, and at least once after break in, if not a third time after another 1000 miles or more. I had to adjust mine before and after break in and again after about 5000 miles. Has this been done? If you haven't and it is out of adjustment you are causing more strain and wear on the transmission internals by not having your clutch disengage fully. In other words, you could be killing your synchros by not adjusting your clutch pedal properly.
