It should swap over perfectly fine. direct bolt on. But watch how high you rev you engine. Your F22 Accord tranny can't handle too much high rpms. or basicly don't over rev your tranny.

I talked to a freind of mine who works at motorsport tech in hayward and he tells me that even though it is a direct bolt on its not a good idea to use a f22 tranny due to basically what asiandude said, the f22 tranny being able to handle a higher rpm. The vtec dosnt kick in until the higher rpms, which means that your f22 tranny wont support much of that abuse, almost making it impossible to use the engine for its purpose (high end torque). I understand everyone is tight for money (even me) but if possible it would be best to save your money for the h22 tranny, youll thank yourself in the end, it would cost you less to buy the engine and tranny in a package too. It will also save you alot of heart ake of swapping out trannys after a engine swap. Another thing you would want to look at is how many miles you have on that f22 tranny aswell, that will also determine the life and its ability to handle a h22 engine.

This was all before I got into my car accident. No more accord for me. Insurance is paying for my car. I am going to miss my accord. Well when I was going to do my H22 swap I was thinking about getting a F22 manual tranny. But I was really looking for the H23 tranny. The reason why is because the F22 tranny has long gears for high top speed also it can't handle the power. The H23 tranny is in between the H22 and the F22 tranny. The H22 Tranny has short gears. So I wanted both put in one and in the middle. The H23 tranny can handle the H22 power also it can be rev up so V-tec can kick in. Also you get an higher top speed than the H22 Tranny. So I would say the your best bet is to go with an H23 tranny if you can find one. Those are a little hard to find.

thats sounds pretty good which i think you guys are right it makes sence so thats what im going to be doing

H22s have about the same gearing as F22s, or at least the H22'd accord that I rode in ran RPMs/Speed about the same as my F22 accord (his 92lx, mine 93ex). The F22s can handle high RPMs just not the torque at the high rpm that the H22s deliver. H22+H22tranny will probably yield a faster 1/4 mile time, but if you want fuel economy or top speed the H22+H23tranny will be your best bet.

They are definitely correct in that buying the motor and transmission together is a good way to save money, however you are gonna be hard pressed to find a H23T+H22M together, so you may want to look around in your local newspaper/listings for a wrecked USDM prelude, and try and steal the engine from there (or buy one from a used honda parts place), just make sure your getting the H23 tranny and not the H22 and you should be alright :).

how would it work for the H23 swap?? I was told (not by a pro) that the F22 tranny would be fine, but then the H23 doent have Vtec. of course its obvious im new so Im curious.

Yes you can match it up, but you can with the H22 as well. The trannies are all interchangeable, however, like mating an F22Tranny to a H22 engine, its more power than the tranny is going to want to take. Don't get me wrong, it WILL work, but the question is, for how long? The H23 engine has more lowend torque which the F22 transmission can deal with better (it mostly struggles with the high end). I suppose it would work a lot better than a F22T-H22E, but I am willing to bet the H23E will work best with an H22 or H23 tranny.
