this sucks man..all this winter my car has been givin me ****..first i need to replace both axels..then i have to take emissions..now on the way home from work today i notice my car is starting to grind going from second into 3rd..it dosent do it all the time only when im at about 8500 rpm or above and shiftin hard..if i shift at 8500+ and shift slow its fine but if im slammin gears it grinds slightly..is there any way to prevent this from getting worse or maybe treat it?..or do i have to replace some **** inside my tranny?..i really dont wanna rebuild it

 

what kind of engine do you have that your consistantly reving it up to 8500+, driving to work no less....christ, you need to calm the hell down in your car

Was thinking the same thing.

 

well aside from the fact that yes, you drive like a maniac
Try double-clutching (I hope you know how to do it right) and maybe gm synchromesh (the friction modified stuff) until you can afford a rebuild (If its even that bad)

 

change your gear oil or another thing you can do is not take it up that high

 

replace your tranny fluid with gm syncromesh friction modified it should get rid of the grind. oh and slow teh fuxor down

edit: beat me to it twice

 

check rear and front lower motor mounts: they may be worn, causing your engine and transmission to unwantedly shake around at high rpm. replace them, fill with window weld, or add es poly inserts and it should stop.

 

im not constantly reving to 8500+rpm but everyonce in a while some old lady needs to have a heart attack because she drives so damn slow

b16 motor and trans

once it happened today for the first time i had to do it a few more times to see when and how it actually happens and i found out it happens at high rev shifts into third only

uhh ok that's smart

anyways try flushing the tranny fluid and putting either some honda mtf or gm synchromesh like suggested before

 

hahah i dont always drive like a maniac ...usually i drive like a garandpa...but today i had to beat on my car to see what and why this 3rd gear grind happens...im gonna be replacing my axels this weekend so when i do that ill try that gm synchromesh friction modified fluid..where can i buy it&gt; i usually use oem honda manual trans fluid

 

yo do realise everytime you shift that high, your syncros have to work over time to match the speed of the gears...they were probly worn down bad already with the way your drive, and your last almighty 8500+rpm pull screwd them up real good...

What do you have done to your motor to be able/ have reason to hold a gear that high? You know the power on a stock motor starts to taper off bad way before that right.....

Btw, 500th post

 

is gm synchromesh friction modified a general motors fluid or is it an aftermarket fluid?..where can i buy it?

and for the last time..im not always shifting at 8500 rpm...i dont drive around racing everyone and everything i see..i was doing some spirited driving and i noticed it grinds into 3rd gear..so i tried it a few more times to see when the grind occurs

 

hm, this kinda helps me too. my tranny grinds going into 3rd, but not like this guy 8500rpm is crazy. well yea, i was told that i would need new synchros.

 

You can get it from your local GM dealer. And also check your motor mounts. That could cause this as well.

 

its not the motor mounts..turst me
