i recently purchased a jdm h22 and tranny, i have been doing some research and the more i look around the more i find out that the tranny on my h22 is for a h23?

I can get ahold of a h22 tranny just wondering what are the pros and cons on the h23 tranny on the h22?

thanks

The gear ratios are surely different.

I know Rich045 can chime in here.
So, the package came with a mix-matched motor & tranny??

well its labeled as a m2j5 which what i read is a h23 tranny.

Prelude13 · #4 (**permalink**) 01-17-2007, 02:50 PM

m2j5, the JDM "h22" tranny..

looks like after 2nd gear, the ratios are shorter than the US counterparts. Also note the final drive as well.

...you'll be constantly in vtec if you live in red.

The M2J5 tranny is good for boost.

na93prepre · #6 (**permalink**) 01-17-2007, 05:15 PM

Correct me if I'm wrong but the M2J5 is a F22b trans right. I mean maybe that trans and the si's are the same gearing, but I'm pretty sure that's a F22B transmission. The M2S4 is the trans I'm using with my JDM H22a. IT's a USDM SI 5spd. I didn't drive this set up yet, but I had this same trans on my old USDM H22A1 and to tell you the truth it's not like noticed anything over using the H22A1 trans. The reason I did away with the H22 trans was b/c it has messed up syncro's from day 1. I personally think the SI is a good trans. I most likely won't stop using it untill I get a nice JDM LSD trans. But right now there's other things more important to me then dropping $700 -1k on a trans. So in my personal opinion it's just has good. Hell maybe it's even a little better on the low end of things.

If your asking if its the same tranny that the accords have then I'm not sure. When I had my 91 accord I wasn't into cars quiet yet. They very well could be the same.

If your talking about f22 in the prelude then its a M2L5.

P.S. I don't remember off the top of my head the f22's codes and where/what they came in lol.

i had the h23 trans on my h22/ h23 hybrid... it seemed to work well, then the motor blew up, and i got a h22a with the transmission... i noticed a huge difference.
the h23 trans like prelude13 stated has longer gears which would deffinitely be good for turbo, but if your staying NA then the h22 trans is ideal IMO? its just up to you what you want to do...

runtingz · #9 (**permalink**) 01-19-2007, 01:07 PM

i need to be corrected and given an understanding of this subject... wouldn't a street daily driver rather h23 tranny over h22 since h23 has more balanced gear ratios and having a longer 1st and 2nd gear over the h22? doesn't it give you that edge when running up against a car from the line?

because ive noticed that gives me an edge over the other cars, i think h23 tranny has very long gears, si?!

...anyway give me some input!

H22_sleeper · #10 (**permalink**) 01-19-2007, 01:41 PM

you can daily drive on either trans and be fine, theres not much difference in the low end, its all about the top end of the gear that you want to worry about if your "racing"...

the H22 trans is going to get you better pulls if your dropping gears, because of he shorter gears, therefore you'll be in the higher RPM range... justa trans change i ran .6 seconds faster in the 1/4 mile (going from a h23 trans to a h22 trans) the H22 trans helped me alot, it has better gears for NA IMO

mix n match the gears, and there you have an amazing trans im sure?

na93prepre · #11 (**permalink**) 01-19-2007, 02:58 PM

you ran over a half a second better?????

runtingz · #12 (**permalink**) 01-19-2007, 05:27 PM

damn thats hot, i didn't know the h22 tranny gave that much improvement...guess im wrong! my bad!

na93prepre · #13 (**permalink**) 01-19-2007, 09:44 PM

me neither. now i feel like a idiot thinking that i was good to go with the h23 tranny for so long. kinda makes me wanna get a h22 trans right -a-way

H22_sleeper · #14 (**permalink**) 01-20-2007, 01:45 PM

i put down about the same hp #'s but about 5lbs of tq less with the H22 swap, so i assume had i had a H22 trans with the hybrid motor, id of been a bit faster... but yea a little over a 1/2 second faster with the H22 trans

na93prepre · #15 (**permalink**) 01-20-2007, 04:00 PM

it just blows my mine that by using the h23 trans you'll be over a 1/2 second slower. Which in theory means if I could run mid 14's consistantly with my set up now I'd really be running most SI (h23) times of low 15's
I'm kinda sad......

MidnightRayne · #16 (**permalink**) 01-20-2007, 07:15 PM

i i can see where it would be different in the first few gears but not by awhole lot. the final drive is the same these two tranny's, keep in mind guys this is my daily friver so i think it will be fine, im not going to turbo it anytime soon( in fact i doubt i ever, the other car is turbo i dont need another). Thanks for all the input tho.

98vtec · #17 (**permalink**) 01-20-2007, 11:12 PM

a 1/2 second really isnt all that long of a duration, but you will be noticebly faster with the shorter gearing of the h22.

rich045 · #18 (**permalink**) 01-23-2007, 03:19 PM

yes i see both your arguments but there are cons to them.
For beginners the h22 tranny (the most common) m2a4 has great intial ratios but 4th and 5th suck...for most of us that is since we use hte lude as a daily driver.
the h23 intial ratios m2s4 are aii but could be better. 5th is better than the m2a4.

thats why i am gonna build me a hybrid tranny. using the m2a4 bell, initial ratios and 5th out of the m2s4, throw new syncros and a quaife.

have a great day =)

PS: o yea, i forgot, i already got both trannys, about to pick up a usdm h22 tranny to swap in for daily drivin while hte otherones are worked on... MUAHAHA!!

98vtec · #19 (**permalink**) 01-23-2007, 03:29 PM

thats what aftermarket final drives are for

rich045 · #20 (**permalink**) 01-23-2007, 03:31 PM

too lazy to get aftermarket parts, i already got everything i need =)

runtingz · #21 (**permalink**) 01-23-2007, 03:38 PM

yeah 5th gear for h23 trannys are lovely...i feel like im in 3rd on the highway, and its great for the open road...but 4th gear is def a weak gear, either that or my transmission is going

na93prepre · #22 (**permalink**) 01-23-2007, 04:34 PM

see i always thought my h23 trans was great on my H22a1. On the hwy it was sweet. I only went 140+ sometimes. Usually to impress girls haha. I never really thought my RPMS dropped to far. I'd shift at 8k and when the clutch was out the rpms would be around 6500 so I was always in the power band. But now that I know it's a half a second difference on the track maybe I will build something like Rich. Hmm any after market ideals? I never really looked into it.

if you could get a deal on the tranny like i did, i say do what i am doing, if not, i am pretty sure there are other companies out there that sell aftermarket gears.

na93prepre · #24 (**permalink**) 01-23-2007, 06:05 PM

Again with the slowness Rich..............

98vtec · #25 (**permalink**) 01-23-2007, 06:54 PM

there are aftermarket synchros and aftermarket FD's but to my knowlegdge there are no aftermarket 1-5 gears.

rich045 · #26 (**permalink**) 01-24-2007, 09:53 AM

thats what i ment... i know they have syncros, and they are fairly cheap. i never heard of any gears... i dont even think they have a topdog tranny (i think thats the name) for us... i know they have it for the Bseries. unless you wanna do a h2b. h2b kit is expenssive

vervuurt · #27 (**permalink**) 06-03-2008, 01:14 PM

Anyone Has A Site To Aftermarket Syncro. And More Parts???

Bezzina · #29 (**permalink**) 06-13-2008, 09:38 PM

so i have a 93 JDM H22a in my del sol.
My tranny went (sorta, i lost reverse) and i have the option of getting an h23 tranny for 200$ and installed for 200$.
ANYWAYS. what i'd like to know is, can i take the gears from my h22 tranny and put it into my h23 tranny and call it a day?
If so, which gears should i swap into the h23 tranny. I heard i should swap my 1-4 from the h22 into the h23 and keep the stock h23 5th?

Suggestions would be extremly appreciated!!!

Prelude13 · #30 (**permalink**) 06-13-2008, 09:45 PM

I would just get a new(used) transmission instead of doing what you said. Cost wise and also performance wise, there are other(better geared) transmissions out there available -
http://preludezone.com/showthread.php?t=1980

and you like the h23's 5th gear? it screams on the highway at like 3k rpm doing 60mph!

...oh, and h22 in a Del Sol? that's hotness!
