my car is grinding when i try to put it into 3rd at high rpm. it grinds when droping gears at about 70 or if im changing from second to 3rd at high rpms. Its only 3rd gear and i was wondering if anyone knew what the problem could be.

 

Synchro. I have the same problem. I already changed my tranny fluid over the weekend, and it still does it. I am going to purchace 3rd synchro and possibly 3/4 gears.

 

well how much is that going to cost me.

 

Try and call the dealership, ask for 3rd gear synchro, and 3rd/4th gears.
I believe the synchro is 70~100 and the gears are like 250~300. I don't know for sure. (i have a friend that works at honda, and they are hooking me the f*ck up) the labour is going to be your main concern unless you do it yourself... all in all...like 800~1000...at the most. I might just cost you like 300 you never know until you ask.

 

here is a post I made yesterday.

acura wouldn't sell me just a 3rd gear synchro -have to buy 3rd gear set -it's $240 -evans honda specialist said -$250 installation if i bring the tranny, but $250 more if they pull the tranny.

 

Get your syncros changed. Costly

 

My friend works at the service/parts desk at Acura and I still couldn't get just the 3rd gear synchros.

If you have a manual, you shouldn't have a problem servicing your own tranny. Otherwise, the $250 quote seems pretty damn good if you know how to drop your tranny.

 

You need the 3-4 Synchro.. no need for a new 3rd gear.

its called the Sleeve set (3-4) and is $158. Not too hard.

it costed me around 700-800 dollars parts and labor to change my third gear synchro, bearings, and seals...

 

thanks
