If you don't mind me saying, why are you obsessed with keeping the auto tranny. I think no one is commenting on the subject because they all convert to manual went doing the H22 swap. Is keeping the the autobox worth all the effort?
Ok here is the story. I use my lude as a daily driver in the summer time and max speed is not a issue. BUT convience is. I don't like shifting all the time. i like holding my girl's hand in city driving. not to mention i don't have the money now to get a conversion.
So my engine wasn't taken care of very well by the last owner and its smoking a little bit and bad valve sound, etc. So i just want to swap the engine.
So to make me happy i just want a h22a with my ol slushbox. If i was going to get a race car i would get an acura integra or something much faster.
What's the point of putting a h22 in then? Seriously, an auto tranny would just lag the crap out of it and render it useless. I would just stick with the h23 and get a good used one/rebuild one (probably cost you less than buying a h22 long block).
As for holding your girl's hand... i still do, just quickly shift with your left hand ... haha... or you can tell her to hold your hand while its on the shift knob..

The real trick will be making the tranny allow the revs to go high enough to get into VTEC. The H22 and H23 are almost exactly the same below 5XXX rpm's and getting an H23 slushbox to go that high would be pretty hard.
I think you can get JDM H22's with the H22 autobox still attached for near the price of the longblock. Since most LB's come from auto ludes it would prolly be easier to get the tranny. You could then get the ECU and be set. Also, I think JDM 4th gens came with a "sport" mode in the autos so if you could figure out how to wire that up you should be on cloud nine.

Good luck,
Yeah I don't know about that one....you could get an H22a Auto ecu, but will that allow you to go to 7400 rpms or what?
i have a jdm h22 and jdm h22 auto tranny ajnd i have no problems with it...i ran a 15.2 but this is with my exhaust leak, bald tires and bad ignition at the time...now that all of this is fixed i am def into the high 14s...my car feels quick as hell for an auto and on a roll i have NO problem keeping up with 5 speeds of many cars that run high 14s...from stop to go it is on the sluggish side but not as bad as everyone is making it sound...i am looking to convert to 5 speed only so i can get the experience of doing the swap myself (going to technical school for cars) but if not for that reason i would keep it auto and love every second of it

this is only 1/2 right...he will need the h22 auto ecu only to make sure his motor runs right and goes into vtec...he will need the jdm h22 auto TCM (transmission control module?) to allow his car to shift at 7400...i didnt know this and i still have my h23 tcm and when i am in D4 and gun it, my car will shift at 6400-6800, never a constant number due to vtec makes it unpredictable for the tranny to shift at the same point everytime...i have to use my D1, D2, D3, D4 to shift above 6800...it works and the car is 1000 times faster doing that but i dont know how good that is for the tranny to keep doing that at high speeds?
and as a side not...i think by using the h23 auto tranny you will not be able to shift into gears and stay in vtec...if you get the tcm or do what i do when you go from 1 to 2, 2 to 3, and 3 to 4 your rpms with drop below 5000 due to the difference in gears and you will have a split lag again till you hit vtec...imo that is the only reason i can see shifting above redline in our cars

Yes but could i use a VAFC to lower my Vtec engage to eliminate that lag?
that should help fix that...i would get the complete package though for the auto swap...just make sure to get the tcm...i am not to sure how the gears are in the auto h23 and i dont know how they will hold up under high shift points
