Hey, so yesterday was my first time drag racing ever, I was really nervous and the first time got 16 flat cause I missed 2nd and 4th cause they didn't wanna go in, so the next time I showed my tranny who's boss and shifted really hard, it grinded going into 2nd, 3rd, and 4th just for a second but went into gear everytime, it never does this daily driving and even below 7000 rpms, it's just when I'm really high around 7800 rpms shifting, so is there a way to fix this so it doesn't grind? Better synchros perhaps? I got an 93 jdm h22a into an integra. Thanks for any help.

 

shifting too high at 7800 rpm will grind. is the motor modded?

 

you can shift an h22 trans way higher than 7800 with no problem, you just need to make SURE that you have fully disengaged the clutch from the mainshaft so the syncros can do their job....

a twin disk clutch is optimum....

 

yeah with no power at 7800rpm

 

yeah unless its built idiot, the point of this thread is not h22 powerbands its the transmission

 

Thanks for the replies, especially bb4ever they seamed very helpfull, yeah maybe I should bleed my clutch and adjust it, cause right now it engages almost as soon as I lift my foot off the clutch from the floor. Only reason I'm shifting at 7800 rpm is because that's where it's made too, h22a makes peak power at 7200, the idea is shifting into peak power, I'm assuming that ppl aren't dumb and that they simply don't know this. Also I'm pretty happy my second run I made I had a reaction time of .6s flat, anyone know if this is a good 60 foot time? 2.3 sec was my best, on crappy street tires.

 

ooh well you need to adjust that clutch badly, the fact that it engages all the way down there also means that it disengages down there.....you should adjust it and raise that point up...

also, you would be better off shifting around 7500 rpm.....and you ought to be able to pull 2.2 or 2.1 60' times....

 

Jus wondering what oil you have in your tranny? mind did the same...try and zip ty your cables every 2" that might help...it did for me...

yeah defnitely ziptie the cables together if you already havent, i did that and it also felt great afterwards....

only use honda MTF, thats all you need....

 

Unless you have an LSD.

 

unless you have an LSD then what? I only ask because I have one and I don't know if it needs special maintenance.

unless you have a viscous lsd, which is completely seperate from the transmission case, and you fill it seperately, and STILL FILL THE TRANSMISSION WITH HONDA MTF

 

zip tie the cables?

 

MTF isnt formulated for LSD.

When you have an LSD you want to use a higher weight fluid. I use 75 W90 Royal Purple (specialy forumulated for LSD's). Its about 10 bucks a quart (takes 2 to fill the tranny). Its a little on the expensive side but I havent had any problems AT ALL with mine, and I've use nothing but this fluid.

the stock lsd uses oem honda fluid in japan, as it should over here in your transmission....there is no necessity for special fluid, honda designed their lsd to use honda mtf

NOW, if you're using some aftermarket or other lsd that reccomends heavier weight fluid, go right ahead, but oem honda lsds do NOT require special MTF

 

Yeah I got an m2b4 no lsd h22a tranny and am using HMT fluid. It's been working great for me so far. I think it would help if my engine revved down faster, when I switch gears, my engine revs about 200-300 rpms up then comes down, instead of just revving straight down, and I AM taking my foot completly off the gas pedal. And also it doesn't bring the rpms down smooth, it goes down to 700 then bounced back to 1100 while I'm moving, it's kinda annoying cause it shakes when it goes down to 700 a little bit too.

 

dont mean to thread jack but what cables are you guys talking about zip tying together? tranny cables? what does it do for you?

 

I think it just forces the cable to move thru the sleeve better rather than deflecting the cables.

 

I thought the high rpm grind was a common prob with H series trans.

 

Yep that what it does I did that to my cables and it runs fine...I'm also running 10w 40w.

I thought all M2B4s have LSD, that's why it's an M2B4 and not an M2A4.

 

yeah man, if you have an m2b4 you DO have a factory lsd

youre pushing the clutch in too early or letting off the gas too late....motors dont just jump 300rpm for no reason....

 

Yeah my bad, meant m2a4. Anyways, I don't know what it is but the rpms do jump, it doesn't do it when I take my foot off the gas for a couple seconds, but when I'm shifting it always does it. My brother who is a mechanic notices it and my honda mechanic friend. It's really weird, like the throttle is lagging. Today it had a very annoying problem that it hasn't had for quite a while. When I accelerate and deaccelerate the car jerks through the rpm like the fuel or spark is cutting out, and also when I take it out of gear if it's below 3000 rpms it will stay there untill I stop, then the idle will surge, I occasionally get the tps code, like once or twice a month, but I'm not sure why, cause the voltage on it is fine. Thanks for the help so far guys.

 

sounds to me like the throttle is getting held open....check to make sure your cable is adjusted right and that there is nothing physically holding it open aka dirtiness etc....

also make sure the throttle stop screw isnt too far up...
