i highly doubt its my idle but i really wanna kno why and what causes it to happen. ima end up with no reverse and ima have to end up buying a new transmission!

Can any1 please help me out,

Thanks

sounds like your reverse synchro is gone....

shit dude you think? it grinds once in a while but it really annoying and its worrying me :dunno:

yes, gnerally when a synchro is going out... it will start to grind

fack. the synchro usually cost about 160 at the auto zone by my house.

u kno if any other places where i can get one for cheap?

nope, by the time my tranny starts to grind, im getting a new car anyway so i just sell it

dam now im outta options

see if you can get a used tranny, usually they test them to make sure they dont grind before sale

ok man thanks for the help

Are we all not aware that reverse is a non-synchro gear? It's constantly engaged... never mind.

haha wow, you're right, when i hear "grind" my mind automatically thinks 'synchro'

I wasn't sure if you were messing with this dude...

Anyway, OP: Your reverse gear is grinding for one of these reasons:
1. Your clutch isn't "winding down" before you put the car into gear.
2. Your clutch is overly worn and needs to be replaced.
3. Your vehicle has not stopped moving before you put it in reverse.
4. You're not fully depressing the clutch pedal.
5. You need to check/add/change your tranny fluid.

Now, the reasons these things are valid answers:
1. Clutch "wind-down time" is a necessary thing. This is the time it takes for the clutch disc/input shaft to reach the same speed as the gear you're trying to put the transmission into. Obviously, this would be 0 RPM, since you're not moving.

2. The clutch being worn, I can't remember why this fucks up your gear changes, other than engine revving higher than the speed you're at for the gear you're in, but this doesn't apply to reverse, because you're not supposed to be moving when you put it in gear.

3. Obvious. Same reasoning as #1, and the reason I keep emphasizing that "you're not supposed to be moving when you put it in reverse."

4. Also obvious. Not fully depressed means clutch isn't winding down properly. This will allow you to shift anyway into forward gears, since they have synchros, but reverse is non-synchronized, and straight cut. It will not engage w/o grinding if there is any resistance.

5. Yes, your tranny has fluid. It's either 5w30 Motor oil, or Honda ATF/MTF. You need to check/change it. It's the only thing that remotely acts as a synchro for reverse, so if it's low, there is a good chance that it will cause your tranny to grind that gear. Don't bother attempting to check it, just change it.. it's a cheap fix.

not messing with him, just not thinking.. haha.. good job Dropzone. Thanks.

No problem... now we'll see if OP actually pays attention and reads the information, or if I just typed all that to help some newb that actually uses the search function sometime in the future.
