Grinding Gears! (2nd)

So me and the old man got most of the major mechanical fix's done today. Bought the car without it being drivable, but the engine sounded good.

All in all:
-New clutch master cylinder
-Removed damper
-Fixed ground (starter would short out)
-Removed alarm / rewired ignition
-New alternator
-New rack and steering / tie rod ends
-New gauge cluster (in the works)
-Fix high idle

All small things, bought the car for 1400 with the h22a swap, I'm pretty satisfied with it.

Now that all of the work is done, we took it out for a spin. It drives great from what we can tell (didnt fully engage vtec but touched it).

PROBLEM:
Going into 2nd gear it grinds, same from 3rd to 2nd (80% sure). 2nd gear itself is fine, and all other gear shifts are fine too. The old man said something about a bad brass gear, the transition gears in between the main gears.

Has anyone had a grinding problem before? Any easy ways to check for the problem more without ripping out the trans, or easy fix's? We're talking about bringing it to a transmission specialist but I know they're going to jerk me around and get me to drop tons more money then I need. =/

Re: Grinding Gears! (2nd)

Oh and on a separate note, is there anything inside the glove compartment lid? Like an airbag?

The original one on my car was broken, so I got one out of a junkyard, same exact thing, but its like 3 lb's heavier.

Someone said maybe an airbag, but I dont see how it would know to deploy. I'm convinced its filled with a kilo of coke, or a bunch of 100 dollar bills. It wont come apart so I can't look.

When times get tough I'll be sure to break it open, just in case.

Re: Grinding Gears! (2nd)

the brass ring that your father is talking about is the synchronizer , its made out of brass.

the brass ring help to slow down the gear when its being engaged.


change your fluid, that could solve your problem.

Re: Grinding Gears! (2nd)

yup, maybe its the tranny fluid, unless it was put in when the clutch was changed. You should just try the tranny fluid it'll cost you bout $15 max.

Re: Grinding Gears! (2nd)

Hey man, reading this and seeing your so close to getting your car the way you want it makes me want to go out and tear the cluster out for you right now haha. Any chance you want a passenger side airbag? I still got mine, undeployed and still in great condition, hahaha. Just lemme know

Re: Grinding Gears! (2nd)

Still grinds. -.-; Probably the synchronizer. It's not a dire problem, all I'll do is end up eating it more, but there should be no harm done to the gear itself right?

Re: Grinding Gears! (2nd)

he was referring to the brass blocking ring its what actually spins the gear up to speed so as the gears engage on the syncro they are moving at the same speed . 2nd is usually the first to go in my experiance , the gear most snached on lol

Re: Grinding Gears! (2nd)

3rd can be pretty bad too, considering the shift from 2nd to 3rd is considered to take the largest toll on the tranny.

Re: Grinding Gears! (2nd)

Try some pennzoil synchromesh fluid, the kind with friction modifiers. I used it on my old integra and it stopped the third gear grind completely.

Re: Grinding Gears! (2nd)

I found the difference. I have the new pennzoil, its not the right one. The dealer in my town sells the original GM friction modified, I'll pick it up monday.

Thanks

Re: Grinding Gears! (2nd)

make sure someone hasnt put 10w 30 in it 92 93 said it was ok 94 95 96 said could be used temporarily until you could get honda fluid . i had an lsd tranny in my 93 we used 10w 30 ( per alldata ) and it was hard to shift and would grind some times . changed it out for honda mtf and it smoothed right up . dunno why alldata says its ok for 92 93 and not for latter years . but it helped my tranny .

Re: Grinding Gears! (2nd)

I have a jdm engine, so I really dont know the year. Could be any 92-96.

We're trying a few fluids, first was the pennzoil mesh. Next is the actual gm mesh with friction modified. If that doesnt work, I'll probably to go the original oem fluid. If the grinds there, its there.

I'll get it fixed in 2 months time for a hefty 750. Just trying my best to lessen the strain. I'd skip 2nd if I was an experienced manual driver.

Lucas is also an option we're thinking about. Thick stuff.

If you're that worried about it, just take it to 4-4500 rpms in 1st, then go straight to 3rd. It'll be a little slow but it'll be fine.

Re: Grinding Gears! (2nd)

The friction modifiers won't work right away. Give it atleast 200 to 300 miles of driving to see if it gets better.

Re: Grinding Gears! (2nd)

Thanks for the info miata, I will.

And bdb, thats what I plan to do for awhile. But, ahem "you can't fix slow." ;)

Casual driving I can avoid. But if I need to show someone up at the light, I'll need 2nd. I dont like to half-ass things, so it WILL get fixed, just not tomorrow. I'll wait till my school pelgrant comes in, and the have it pulled out and looked at. That is if it doesnt fix itself with the new fluid, can always hope.

try the honda fluid first was what it was made to use with . before id get it rebuilt id invest in an lsd tranny well worth the money . i used to have one in my 93 traction and corner grip is amazingly better , just my 2 cents by the way 750 is steep . especially if your removing it yourself . the parts are not expensive and honda manual trans are easy as trans get to work on ...

Re: Grinding Gears! (2nd)

I've did some research. People either swear by honda MTF or gm mesh. From what I read, use honda MTF if you're trans is good working, it'll maintain it. But if its slipping or grinding, convert to gm mesh. That was what I got out of it anyway.

175 to take it out and put it in + 300 for general labor + 300 for 1 & 2 sncyro gear sleeve from an OEM part site. =( Other people quoted me 1000+.

Tell me more about this LSD tranny? Where can I get one?
