so the other day, i was running my car pretty hard going at about 85mph and was ready to shift to 6th gear and then i goofed...i grinded pretty hard on my gear. it seems as though i released the clutch before i put in gear. i know, flame on me as much as you want...pretty embarrassing.

now i noticed that when i drive, i noticed that it is more "notchy" than before trying to shift into 6th gear. i'm wondering if there is anything i can do to possibly fix this problem? i am pretty sure that this is a direct result of my crappy shifting.

can you guys help me out and let me know to confirm that this is a correct evaluation on my part?

thanks!

if COULD be all in your head, i know its the end of the world when you grind. it certainly feels like it. but im sure that the feeling is all in your head, just keep driving and dont think too hard when youre shifting, just shift.

i hope it is all in my head, but i tell you that 6th gear for some reason is like my achilles heel for me...heheh

People grind gears all the time. I've ground my 3 - 2 shift from time to time. Sure, it wears down the syncros. Even normal, daily shifting will put wear on them. It's a mechanical part that gets used. They wear. Grinding wears them a bit sooner. Not a real big deal.
There is nothing you can do about it except to remove the tranny and tear it apart to put new syncros in. You really wanna go to that extreme for something that may be mostly in your head?
Having said that, here's something to play with your melon:

"Gear grind" is just a terminology people use. So please. Educate us. What exactly makes the noise that we hear when we grind "gears"?

well, i know u are very knowledgeable and prob know exactly how everythign works already, but for everyone else that doesnt know yet i guess i will.. try to inform a little bit.

Becically you have your free spinning gears on your main shaft. you have a hub that is splined to the main shaft with a splined hub sleeve that slides back and forth on the hubs via the shift forks moving.
When you are trying to put it into gear and the hub sheeve pushes the syncronizer ring to slow down the speed ring and the gear u are trying to go into. when syncronization of the rings and gear occurs, the hub sleeve will slide over them all and lock the gear down.
Just to give everyone a better visual of what is happening. the power comes in the front of the imput shaft, goes down to a counter shaft, then back up to the selected gear and out the output shaft.

So the grinding is when you are pushing it into gear and the syncronizer ring and the gear collar arent spinning at the same speed, and it wont go into gear.

Sorry if this makes no sense to some people, I just wrote this real quick to give ppl some idea and didnt proof read it to see if it actually made any sense, and im kinda bad at describing what exactly goes on, if i had a trans infront of me i could explain everythign that is going on but i suck at putting things in words.

and viper, sorry, i wasnt trying to be a smarta$$ or anything. so if i offended anyone, i apologize!
