Just recently, like night and day, my gearbox got really notchy. There was no gradual notchiness or signs (except maybe a slight grind sometimes from 2-3 gears). I just got back from a track event last weekend too, everything has been fine up until now.

I just installed a JDM itr LSD into my tranny about 2 months ago. Everything was fine up until now. All of the sudden i can't shift with one smooth motion no matter how slow i shift. It's like a hit a gate, then i have to wait a second or two until i can finish the shift to the next gear--and it doesn't matter how hard i push or pull into a gear, it just gets stopped until it seems my tranny "accepts" the change into the next gear. This happens 1st -5th gears. It happens about 90% of the time when i'm driving as well. About 10% of the time my tranny acts normal--smooth shifts, like nothing is wrong.

The other problem that starting happening w/ above mentioned problems is what i can only best describe as my car "shuddering" when i want to take off in first or reverse. It's like when someone doesn't know how to drive manual and they don't give it enough gas--that kind of shaking/shuddering.

Now i searched and i did the easy stuff--i bled my clutch, i changed my tranny fluid from honda mtf fluid to redline mtf fluid.

It makes me think it is either 1) the clutch, 2) the throwout bearing or 3) some internal problem in the tranny relating to my LSD install (ie maybe a loose bolt on the changeholder).

The clutch seemed fine when i drove it for the past 2 months, and at my recent track day..... and does it make sense that my car would act like this if my clutch were bad? i have no idea. can anybody offer any suggestions?

come to a complete stop and pull ur ebrake. put in in 5th and give it some gas and let the clutch out. if your rpms continue to rise with the clutch engaged then ur clutch is toast.

interesting...are you having the same symptoms as me? maybe we did something wrong on the lsd install. how many miles have you driven w/ the lsd in?

ic. i thought that maybe i had not shimmed it right or something like the changeholder came loose.....but i have no idea right now. Maybe it is as easy as a worn clutch in my case? i still have to check it. Although i dont see how my tranny can go back an forth like night and day from notchy to good. This is kinda what makes me think it's not my clutch.

Leo C

difficult to shift can be alot of things-
clutch adjustment(1 inch of free-play @ the pedal)
synchronizers worn
pilot bearing seized
shiftlinkage or bushing seized
clutch release system-stretched cables, worn linkages
broken, cracked or fatigued clutch arm or release arm pivot
damaged clutch hub damper or damper spring
defective clutch disc

id be willing to bet that it is clutch related and not having to do with ur synchronizers

Thanks, yeah i'm preparing my wallet for the chance that i have to buy a new clutch. But i'm going to take my car into a couple shops on monday to get professional opinions when i let them drive my car.

GR_DC2

i was suggested to check my slave cylinder...anyone know how to spot a bad SC?

Leo C

i believe they leak if they are bad.. i might be thinking of the mc tho

GR_DC2

bad news....well i just replaced my CMC, and it didn't fix it. I guess its my clutch.....

Can anyone suggest a good clutch for me? I have no idea where to start, for example ACT has so many different types. I don't mind stiff, i drive the car about half of the week and i take it road racing a few times a year.

clutchmasters, act or exedy stage 1 unless ur running over 250 hp

thanks, i'm currently looking at the exedy stage 1. i sure hope its the clutch and not the slave or something smaller.....or this will be an expensive diagnosis so far ($100 for the CMC and around $300 for the clutch + install). My slave cylinder doesn't show signs of any leakage whatsoever, so i don't think it is the problem. And i took the car out again today, and the shuddering at takeoff is happening more and more now.--making me think its the clutch not grabbing.

Leo C

so u still can't tell if ur clutch is slipping? try a hard launch if see if the rpm's rise w/out the car's speed increasing

GR_DC2

ok i just went out and tested it again.

Basically right as i get to the friction point on the clutch, my car starts the shuddering, so at this point, i do see the rpm's rise w/o my speed rising...but i think this is mainly b/c i haven't even let the clutch out all the way yet either. This is why i think the clutch isn't grabbing, am i right?

I tried the hard launch, well i didn't launch it drag race style, but i revved up to 4k and dropped the clutch and it seemed to engage fine. It seems like starting out in a higher rpm is the only way to avoid the shuddering/chatter. only when i try to drive normally, does the clutch feel like it doesn't want to engage.

Here are the pictures finally. You can see what broke off...

Sorry I didn't see this post earlier. Same problem I encountered, all the springs in the hub were loose too. I replaced with an exedy stage 1 but wish I got the ACT street clutch since it has 6 springs on the hub rather than the 4 springs on the exedy and oem.

Hi,

I just ran across your post and read the problem you experienced. I am experiencing the exact same thing. I couldn't have done a better job at describing the problem. So, you had to change the clutch? How much did it cost you for parts and labor? Only $300?

well i'm gonna join right in on my tranny having the same exact issues as yours, notchy 1-5 gears and reverse is a bitch, i mean pretty damn notchy, like a gate after each movement just as you described. now heres the catch though, my tranny has only been in for about 600 miles so far, 1990 Dx tranny turned into an Si, new mainshaft, countershaft and diff bearings, new throwout bearing, new pilot bearing, brand new stage 1 XTD clutch, brand new flywheel, greased up release arm real nice, new throw out bearing return spring and even replaced the bolt and washer for it, also have a new clutch cable. i'm stumped and the reason this post caught my eye is you said this happened after a track event, just an hour ago i was driving, redlined 1st and missed 2nd like a ************ (not afraid to admit it and i'm a decent driver) and after that now all the way home it has been a definate increase in notchiness, feels like i for sure damaged something, i dunno. Just don't know where to turn with this because the whole gear box is like this.
