hi guys, heres the deal.

ive been told several, several different opinions on this subject and just want to gather some more from yous guys...

h22a lsd tranny = M2B4 4.40FD
h22a type r tranny (w/o traction control) = T2T4 4.80FD

i just got a T2T4 from steve, who assured me it will bolt on and work fine with my h22a. well, some local friends and preludeonline.com members keep telling me this will not work. that its been tried and they dont even bolt up. i know this isnt true, i held the damn thing up to the M2B4 today, exact same bolt locations and everything... okay, so i dont have a concrete question, but what do you guys think? thanks...

I dunno they asked the same question...the only place that came from was Sun, who emailed a guy. So if it bolts up then let us know. Is this the Euro-R (Japan) or Accord Type-R (Europe) tranny? Are they the same. Also, I though the JDM tranny had the same FD (4.266) as the rest of the preludes?

 

see, this is what im saying. so much different info from so many different people, im not sure what to believe. thats the same thread my friend showed me too. i guess we'll have to wait and see. should be on around the 30th...

im not sure which typeR tranny it is. i do know its the one that does NOT have traction control.

well i was gonna ask a similar question but didnt want to start a whole new thread, but if my friends distributor has a JDM H23A4 (h23vtec) accord sir wagon motor but no tranny, will it bolt onto any usdm tranny? would 4th gen si tranny be good, something about shorter gear ratios? and do you know of a online shop that sells tranny's? i'd like to know my options before i go ahead and purchase that motor. thanks guys!

 

the jdm h23 is a H23A, not h23a4.

a 4gen prelude jdm vtec tranny would be ideal but any h-series tranny should work according to the info ive been told

 

an easy way to tell if it is an lsd tranny is to look though where the axels go into the tranny. if you can see all the wa though then it is a lsd model, if there is a bar though the middle it is not, dont know about the other stuff cause i hear so much different info, if i was to guess though, i would say all will bolt to each other, that would keep production cost lower for honda.

btw- i have a tranny for sale, dont know the model # but it is supposed to be a jdm one, and the gears are taller then an si, but not as tall as an s model.

umm actually the pic on my avator, the engine code on it says h23a4...so what would you say that is? from my knowledge its the accord sirT wagon engine.

 

thats kind of weird because...

#1 - i saw the h23 vtec in person and it was stamped H23A
#2 - i was not aware of any JDM motors with a numeric digit after the last letter

 

aight thats cool, well you're probably right cuz i've never seen one in person, but from what i was told its a h23a4. #2 makes a lot of sense, so i think you're right. anyways thanks for corrections or whatever

 

Well let us know in a month! I'm interested to see the results. I'm going to guess it should bolt in fine, but what do I know

E-mail sun dang, he may be able to give more info on it....

 

i will let you know in a month, but i have wendsday off of work so ill try and at least bolt if up then. ill let ya know.

 

You guys sound like you can help.

I have a USDM 4th Gen Prelude 5spd. I purchased a JDM H22A engine and tranny.

The stud patterns for the tranny mounts on the two trannys are completely different. Any idea what to do about this? Like everyone else, I was told that it should bolt right up, but it is way different.

Thanks,

additional question: what tranny would fit a h23a? i really need to know because i think i can get a GREAT deal on just the long block itself. if anyone could answer, that would be awesome.

 

Any H-series tranny(until we figure out this Euro-R/Type-R business), and the F22 tranny for sure...you have a few options

 

UPDATE! all bolt holes line up correctly, bell housing shows no signs of being the wrong size! so far, i am 98% sure this is going to work... will let you guys know when its actually in the car in first week of sept.

 

Speaking of trannies, does anyone know if the tranny on the Type S w/ATTS is any different from the USDM Type SH tranny w/ATTS? Is there anything SH owners can do to improve their tranny and maybe cutback on the hp loss going down to the wheels?

nice that's good to know. Does that tranny come with LSD?

 

yep... and if its the same tranny as the one in the ATR in sport compact car, its the helical(sp?) lsd. i wish i knew exactly what car this was from... anyone know where i can find tranny codes and which car their from?

 

unfortunately I believe the answer is no since JDM and USDM trannies for both the Base and the SH are exactly the same in terms of gear ratios...

 

Thanks Satan, I found that out too searching on po.com... hmmm, time to find a 4th gen Vtec to play with

-Hoc

 

You mean to get the tranny? Unfornately again it won't bolt up because of the SH block

 

Oh no, I meant a 4th gen VTEC lude!

 

I am am replacing an H23 with a JDM H22A engine this week. Should be done first part of next week. So far, I have run into problems getting the right tranny mount which has forced me to use my old transmission and I couldnt use my old headers and the JDM manifold wont bolt up to my exhaust.

 

my tranny code is P2T4.....so what is that from, I have a JDM h22a and this is what it came with..peace

 

um, i dunno but a friend w/ a h22a his came with tranny code M2B4... who knows?
