Could someone please give me a run-down on how strong, or weak, the trans is from a 95 Accord with F22? Is it something I should be buying to use with a built motor, or, like the D series, better to leave alone?

 

What are you wanting to do with it? How much power are you planning to make that your concerned. Details on your setup.

 

Autocross car with something a bit over 200whp.

 

Quick Answer?

Well... the automatic trans is certainly better than it's later cousin introduced in 1998. Unfortunately, there's not many venues offering upgraded units.

......... the standard trans is arguably better, but has lubrication issues if the wrong fluid is used.

P

 

well if we are talking 5 speed transmission... just make sure to use a good fluid and you should be fine at that power level given you dont try to destroy it driving like an idiot. thats something thats pretty common sense though, so I am sure you understand that.

I thought we were talking bigger power and more importantly, lots of torque from per say a turbo build. then I was going to start sharing my experience with cracking a tranny case on the dyno or direct you to extralargenog's gearset destruction pics.

 

Definitely a 5spd. No giant hp but I will be using slicks so there'll be quite a bit of grip. And it's a second gear only kinda thing. Are there other trannies that are undoubtedly stronger?

 

If your planning on running slicks, a clutch upgrade is a must. You'll eat through the OEM after a few good launches. As for the tranny..... in any light, be careful with slicks and a stock tranny.

 

Actually Ive heard a few very wise honda certified mechanics say the 5th gen accord tranny is the best they've put in their hondas.. The gear ratio is long enough where you can add a engine with horsepower, but not to long where its completely top end speed.. Second the syncro trannys in hondas are very good technology. Less slippin and easy to shift at high rpms.

 

I think you should be fine, the stock f trans is pretty decent honestly, I think your going to want to change transmissions or the gearsets for better gear ratios before breakage at that power level.

 

F series and H series 5 spd trannies have the exact same bolt pattern, but the H series trannies have "thicker" gears. And the H series trannies have more webbing on the cases. So if youre looking for a stronger F series tranny, H is the way to go. An F series tranny wont bolt up to a D series.

 

RLY?


Um Ok



For an autocross car look for a M2F4 (4th gen USDM prelude)... Closest shortest gears (as far as the OEM offerings go). Also those and the JDM tranny's second gear has 1 less tooth on the imput shaft (allowing for more material for teeth) than the M2y/s4 and the like. Since the teeth on the imput shaft are what normally breaks first if an issue wiuth second is encountered, its the preffered model for strength...


This is more of a concern with >300-350tq though. I make 450 ft lbs (soon to be ALOT more) and break them regularly, at 200ish WHP you wont have an issue, but the M2F4 would be a nice upgrade for you from the f. Not only are the fs cogs longer, but the FD is as well. Its a shitty choice for autox... actually its a shitty choice for anything other than a stock revving f that you insist on cruising at 2800 rpms on.

If you want a really close ratio box I have a straightcut Foged gearset... 1-5. You wont break it.

Ive blown up more H trannys than most people have even seen. ALWAYS 2nd and fourth... I shatter all of the teeth off of BOTH the gears, and ALWAYS the imput shaft teeth off of second.

PM ME,
Ihaztheanswer2your?sKbai.

On a seperate note, Ive been putting 630WHP on 235/60/15 (26") M&Hs for over 10K miles on BONE STOCK OEM H sweries Prelude axles. Get a Prelude mid shaft and run the axles... NOT any "rebuilt OEM" ones from Schusks and ****... OEM out of a wrecked H series (H22 or H23) lude.

I have YET to replace them and have run low11s on them at the track and beat the **** out of the car.... 100 dollar upgrade beats 1000 DSS axles. Im DESTROYING every tanny i put in the car, and the axles are STILL good, 9-10 trannys later

:O)



No.Wrong. your sources obviously dont make power, but 5th isnt problematic anyways, unless your trying to go 200 MPH, the accord fifth is Crap. DO you understand whjat "long" means????

Blue? Srsly?

No autotragic was mentioned... but there are a few companies around that make frictons and plates, and even offer treatment for internals for the autos... ALso I know this guy, he knows how to allieviate the Preludes shitty pump issue to, in addition to how to modify the vlave body, I didnt plan on running the TCU, instead putting together my own shifter mechanism.

I considered seeing how longit would takew me to blow one up... May still do ity for fun one day.

 

I use 2nd almost exclusively, so the only change would be finals to match speed range to available rpm range. The ratios between gears means nothing, and I've been thinking of eliminating 4 and 5 all together for weight savings of useless parts.

Thanks for the feedback guys.

 

So any strength comparison between F and B series?
Oh, and I have the choice to run what engine I want so what it bolts up to is going to be less of a problem than finding a strong trans, and do a build, on the budget.

 

Extra, do the cases break on you also or has it only been gearset problems? If cases, where are they tending to fail? I like pics, visual aids help my schooling.

 

I ran a 97 Accord trans in my H22 hatch for a couple of years with no problems at all. (and I wasnt nice to it either) I loved the tall gear ratios on the freeway. 80 mph in second! Now Im running a T2W4 Euro-R trans. The gears are super close and low. I actually preferred the accord trans. And they are plentiful too.

 

U send me your email... I send you linky poos... LOL.
