I have a H22 swap in a 91' Accord that has the stock F series auto transmission still. Well its a piece of crap and totally wrong for the motor so I was going to either get a H23 or H22 auto tranny to replace it. My question is what rpms are these tranny's at when cruising at highway speed (like 70mph)?? The car is strictly a daily driver and I do lots of freeway driving so I want something that has relatively low rpms when cruising at freeway speeds. I basically dont want anything thats going to rev much higher than 3k rpms when driving at around 70mph. I would like the H22 trans but I have a feeling its pretty short and I might be better off with the H23. But I have never ridden in or driven a auto H22 or H23 so I dont know.

H23 is a bit longer then the H22 tranny.

You don't want to switch to a manual?

 

Because its a daily driver and I really dont care. Going fast isnt the point in this car (I have a boosted DA for that), the point is to get good gas mileage and be as quiet as possible. I only swapped a H22 into it to begin with because I already had a longblock from a previous project. The motor was originally mated to a 5 speed and I'm running the Prelude ECU from a manual so I'm not loosing any power like most auto H22's. But I'm using the stock F series TCU and F series auto trans and its just not right on the H22 so I need to get a H22 or H23 auto transmission and TCU. I would like to get the H22 trans if possible but I dont want it if the gears are too short.

So does anyone know what a H22 and H23 auto trans revs at when doing around 70mph? Keeping the revs down on the freeway is my goal, I hate my B16 trans on my DA on the freeway.

 

I can tell you that a '92 H23 auto runs 75mph @ ~3200rpms.

I thought there was a thread in the FAQ's with all the trannies listed but I couldn't find it.

 

Yeah, I searched but couldnt find any info.

So if a H23 is at about 3.2k at around 75mph that sounds like exactly what I would be looking for. Unless a H22 isnt much shorter thats what I would probably go with. Anyone know what the H22 is?

 

yeah mine runs at 3k crusing speed h22a atx tranny. but how did u get the manual ecu to work right with the auto, how many rpms can u turn max?

 

obd1 ECU's and TCU's dont 'talk' to each other. My ECU is chipped, no rev limiter and vtec lowered. Never really tested it but it should only be limited mechanicly.
