[ti's 92 accord]

so i was wondering if our tranny would be better with an h22 engine compared to the h22 transion. i have heard that the f22 tranny has longer gears than the h22 tranny. help me out

[benjerman112]

i have a 96 accord ex trans w/my h22a4 i like it for the gas mi. & its still quick.

[black sunshine]

h22 has shorter gears= faster accleration than the f.....so h is better

however for boost (turbo) the f is better,due to it's longer gears.
so if you want boost go with f...if not h is the way bro

[ti's 92 accord]

im thinkning of natural aspiration. so the h22 tran is better. what is the top gear.

[deevergote]

The top gear is 5th.


Define "better". That relies solely on your purpose. If you want a faster quarter mile time, the H22 transmission is best.

Which is better depends entirely on what you want out of your car. I had the H tranny in my car for about 2 years after the swap, then I decided that I wanted to get better highway gas mileage so I swapped in a 90 Accord EX tranny. I also dropped in a Quaife ATB diff (LSD) to get better launches and try to make up for a little bit of the gearing difference. You will lose some accelleration with the Accord tranny over the Prelude tranny.

With the H tranny, I was getting about 24 MPG (average per tank) and I ran a 15.2 in the 1/4 (with lots of bad parts that f'd up my launch) and I was revving at about 4k at 75MPH (0.870 5th with a 4.266 final drive)

With the F tranny, I'm getting about 26 MPG (average per tank) and I ran a 15.7 in the 1/4, but the trans didn't want to shift into 2nd. I found out later that the design of the 90-91 EX trans was weak and that the issue was resolved with the redesign for 92. So if you do decide to get an Accord tranny, go with the 92-up. With this trans, I rev at about 3k at 80MPH, which is what gives it the better fuel economy on the highway. (0.685 5th with a 4.026 final drive)

all of this is true but to get back to your original question....from a performence stand point h is king.

f is a bit better on gas. it's that simple

Nobody deviated from the original question In fact, everyone else gave valuable information, whereas you just regurgitated what was said above and pooped out an opinion with nothing to back it up.




4GAccordH22, I hadn't heard that the older transmissions had a weak point. Do you have any more information on that? I'd like to know more!

I have a 91 and i am unsure as to whether the tranny is original or not but i would like to replace it if this is true.

In the 92 up H2U5 they used a larger mainshaft and a 3 pc 2nd gear synchro. I found this out after I installed the LSD and put the tranny in the car. I called Gearspeed to see about getting their carbon-coated synchros. I ended up talking to one of the techs who told me all of this. He said that they don't even rebuild the 90-91 H2U5, they just trash them if they get them as a core. The easiest way to tell if it is a 90-91 tranny or a 92-up is to look for the mounting hole for the CD/Prelude chassis on the backside of the case, the 90-91's do not have the hole to drill and tap for a Prelude/CD. So now my tranny is getting worse and I can't find one at pick n pull locally, so I may have to get a gearspeed $1400 tranny (with MY LSD installed)...

[bcjammerx]

can't add much more, but I will add this...neither is "stronger" than the other. As it has been explained to me, they both handle the same power (maybe not the earlier H2U5 I guess)

As said...it's an issue of acceleration or fuel economy

Interesting! I love that there are still new things to learn about these cars!

I'd definitely trust the word of GearSpeed.

Yeah it's interesting that every week there is something else i put on my list of things to do to this car...... but i might be in luck... i know my motor was swapped in so i might have gotten luck with the tranny....

Thanks 4G

[totaldoughnut]

Would it be possible to get custom gears for the h series? If so maybe a taller 5th gear for cruising and the rest oem for performance. Or would the f series fifth gear set fit in the h series trans? Whats the price differance between the two? Ive been considering a trans swap also and have been also been debating on which trans to use.

[4GAccordH22]

I'm considering getting a trans (H2U5) from Gearspeed with their carbon coated synchros, but I wanted to ask them if the Prelude final drive (4.266) would fit in the Accord tranny. I know for a fact that the Quaife differential is the same for both trannys...
