Can a F22 series transmission hit higher RPMs than H-series motor because the gear ratio is different? Is this true, because i heard that today when some guy was telling me that i should mount that to my h23 vtec.

 

Not sure what you mean by the transmission hitting higher RPM's. The F22 tranny was only built to shift at a max of around 6500. It will start to grind in the 7 and 8k range.

If speed is your objective, an H22 tranny is the best option, because of the shorter gearing. Shorter gearing = faster acceleration.

 

so other than different ratios, what's physically different about the internals of the F22 trans that makes it "max" around 6500?

 

The F22 5spd trans will not grind. I've taken mine up to 7.5K rpm and that was the max it will go; it'll bounce off just like hitting redline. After I got my F20B T2T4 LSD trans installed, I can finally go up to 8K MAX.

Your gears will be longer and your car will be slower if you mate the F22 tranny with an H23 or H22.

 

okay, well this isn't really helping. I have an h23 vtec (h22 head on an h23 block with h23 trany.) So what i want to know is the F22 trany just as good or better then the h23 trany?

 

that is what is different. the internal gears are bigger. and they can only spin so fast, and if the gears were smaller (meaning the H) they can spin faster. hence why the H acn rev higher (engine and trans) as opposed to the F (engine and trans)

 

If your NA, then the H23 tranny would be better due to the shorter gearing. An H22 (M2F4), or an f20B SiR (T2T4 LSD) would be even better.
short Gears= Faster accel
Long gears= higher top speed (but who goes the top speed anyways)

 

JEFF GORDON!!! THATS WHO!!!

And yeah, davey has the right idea here.

 

the gears are bigger...? you mean they are longer. this won't effect max engine rpm, only how long it takes to get there. that's what i'm trying to get at.. there is no reason you can't spin the gears just as fast in the F22 trans compared to the H22 or H23.. you'll just be going faster.

in the OP's case, his engine can rev high and fast and if he wants to take advantage of that the H23 trans would be the choice. for lower revs at higher speeds (higher theretical max speed) the F22 trans.

 

i put my f22 trany out of a 94 accord ex,on my h22 cuz im making her a dd and good gas mileage is what im looking for,

 

If you read what I wrote earlier:

"Your gears will be longer and your car will be slower if you mate the F22 tranny with an H23 or H22." Meaning it sucks but good gas mileage, and your H23A VTEC will be slower if you're looking into more acceleration.

 

nobody want good gas mileage

 

is their certain years of the f22 trannys that dont match up with certain years of h22 or do they all mingle?

 

entire production run, 1990-97 and on until 2002 with the F23 should all work. (manual trans, to be clear) all H-series and FWD F-series share the same block-trans bolt pattern.

 

you say f23....this may be a dumb question but that includes f22 also?

 

1990-97 is F22, 98-02 is F23. Both of those and the H22 and H23 will bolt up.

 

the F23 can be considered a bored and stroked F22. there are other differences but in general...

 

Anybody have any experience with F22 engines and transmissions imported from Japan? There's a local place that imports engines and transmissions from junked cars in Japan. They claim that they only have around 30K miles on them and are out of running vehicles.

They want $395 for a used auto tranny for a 1991 Accord. Is this a reasonable price?

 

Anybody have any suggestion on where to get a transmission?

 

Seems fair to me. Locally(just down the road) I was able to pickup a Japanese transmission for the Accord. ~$500(US) out the door, with a small warranty. Japans Shaken test can become costly for older cars, so often the cars are either exported or dismantled and the parts exported. Mileage on these cars varies from 30-50Kmiles. Considering these transmissions last 200K I think you have nothing to fear.

Transmissions from Honda are ~3500 for what I was quoted.
Local shop stated he could rebuild/install the current trans for ~2500.
Local Importers wanted ~500 for the transmission.
