i have a 2000 gsr with 78,000 miles on it. When i drive in first gear up to 3500 rpm, it makes a crunching noise which i think the noise is coming from the gear box. If i shift into second at 3500 rpm, it makes a longer crunching noise. My friend ( who has a itr ) said it might be the synchros. I would like to know how to fix this problem. Other than that it runs great. FYI-- the clutch and shifter is all stock. Got the car stock two weeks ago. Any help would be appreciated. Thanks

Sounds like your synchro's are very worn. Where did you buy the car? I hope not from a private party. Did you test-drive the car at all before you bought it? If your synchro's are worn out in the first few gears (or any for that matter), it's going to require a professional tear-down of your transmission. If you don't know much about transmissions yourself I suggest you take it to a reputable shop and see if they can diagnose exactly what it is. You may be looking at around a $400-500 repair if it is the synchro's

thanks for the help. I did test drive the car as well as my two friends who run and own their own shop. It definitely did not make the noise until a couple of weeks after i bought it. Thanks again.

Actually it'll cost more than 400-500 bucks for a rebuild at a reputable shop. A tranny is more complicated than an engine so it's a more involving rebuild. Your better off spending $400-600 for a new GSR tranny.

Thanks Jgears and spoonteg, i appreciate the advice, i will probably (definitely) try the transmission fluid and save up a bit to see what i should do about the trans. Thanks again
