i have a h22 in my accord. i kept the original auto trans from the car, but sent out the valve body to level 10 to get reworked. i kept the auto trans because i do a lot of city driving and shifting a lot gets tiring. whats trans you decide is up to you. the f series trans are geared longer, so you'll get a better top speed. h22 trans are a little bit shorter, so you'll be quicker, but you wont have as high of a top speed. if you're really wanting to be quick, they do make adapter plates so that a b series trans can bolt onto a h22. pick the trans for what you're gonna use the car for.
