I Just changed my clutch on saturday and ive been driving it for 2 days. im not driving the car crazy because i need to break in the clutch but today on my way home whenever i shift to 2nd gear it keeps grinding and when i shift to 3rd u could kind of feel it grind but its worst on the 2nd gear can anyone help me please?

Bleeding the clutch. I bet that will do it if it was not grinding befor Saturday.

as Nik stated above, or it's your syncros starting to go, i know with mine, i have to be gentle with it in 2nd gear or it'll grind, i've heard also that syncromesh works good too.

NIK90s13 · 04-03-2006, 08:27 PM

Yea I thought of syncros, but did'nt want to ''jinks'' him.

Try a good fluid if you haven't already.

aznpoopy · 04-03-2006, 08:52 PM

if you just changed your clutch, make sure its fully disengaging. ebrake down, jack up the rear, start the car, put it in first gear with the clutch pedal fully down. if your wheels start moving a little, you need to bleed/adjust/etc.

Some Redline Shockproof should do the trick, just make sure all the fluids are all warm and moving around before you row through the gears really good though

sncs14 · 04-03-2006, 09:37 PM

I call clutch adjustment

silvia_koukis14 · 04-03-2006, 10:06 PM

thanks guys i was thinking either its the syncros too but for some reason it only grinds when the engine is still kinda cold but once it hits up it drives pretty well and as punxva said to shift slowly that helps alot too but i feel little rubs when i do that. thanks for the help guys

Try wut people said first...re-bleed the clutch line, then play with the pedal adjustment. Feel where it engage and disengages, it should be half way up and down the clutch pedal. If it still grinds, then synchros for sure...change your tranny fluid and go buy some Redline. I would recommend going 1 qt shockproof and fill to the top with MT-90.

kandyflip445 · 04-04-2006, 06:46 AM

And by "to the top" he means to the bottom of the fill hole, with the car level.

Irukandji · 04-04-2006, 11:26 AM

who actually uses the fill hole? I just pour in 3 qts through the shifter hole (a little over but hey its an old tranny). I used Shockproof and I absolutely hated that stuff. Go MT90 and never look back.

-usmd-180sx · 04-04-2006, 11:46 AM

u guys dont use the fill hole, and make a ghetto pump out of the MT-90 bottle? =)

silvia_koukis14 · 04-04-2006, 10:07 PM

i tried changing to mt-90 fluid with a quart of shockproof n i bleed the clutch fluid and its still grinding so im guessing its the syncros.. would it be expensive to replace the syncros? or wat should i do? my friends said to just get a new tranny

240SeXy_man · 04-05-2006, 12:46 PM

yep i have the exact same problem, i recently changed my clutch too and when i first start the car it grinds pretty bad when i put it into 2nd unless im real gentle and 3rd grinds too but not as bad, but as soon as it starts warming up it drives fine...never knew what the problem was, i was just careful but from the looks of this thread looks like i have to change my clutch fluid sweet...

aznpoopy · 04-05-2006, 12:57 PM

ok, first of all its not called clutch fluid. the clutch hydraulic system uses brake fluid. don't take this the wrong way. i'm not making fun of you guys. i just don't want you going to the parts store and asking for clutch fluid.

and if your synchros are bad you need to replace the transmission or get the whole thing rebuilt.
