For someone whos never built an engine but has done just about everything else to a car. How hard like i'm just wondering if i shoulnd't even try. Is it something i can just follow the haynes manual and be alright?

 

I'd say it depends.... on whether or not the tranny is currently working?

If it is.... i'd say no.

If it isn't and it's dead... i'd say yeah, tear it apart and try... ain't gonna hurt it. And you'll never know til ya try.

As for cost-effective........????

 

do you have a press?

i only think you need a press if you are removing the gears from the shafts i dont remember having to use the press for just the syncros, but its been awhile

 

the synchro hubs slide off but i thought the synchro ring had to be pressed off. i really shouldn't talk though because i've only pulled apart 1 trans, and it was a gm .

 

no wait the synchro sleeves slide off and the synchro ring is on the gear and?????? expletive it i hated trans class at school

 

would u suggest just coughing up money to gear speed because of difficulty of doing this. I mean im going for 400 hp d series and d series trannies aren't as strong tranny, so i want to rebuild it before i use it just to be safe

 

its pretty easy actully i can do rebuild two 6 speed trannys in about 6 hours with a 30 minute lunch i also didn;t like it in school . what school did u go to? i go to UTI. but the part that takes the longest is removing the transaxle from the car itself. no need for press either. and its the the sycro sleeve (hub)which goes over the key,that goes over the blocking ring(syncro ring), which goes to the cone of the gear

 

actually, D-series transmissions are stronger than B-series - that is why Bisimoto uses them in his all motor/pro stock car

quote from Bisimoto website:

"Many may ask, "Why the D-series transmission?" These transmissions are plentiful and very cost effective. Since many popular Honda chassis come with these transmissions from factory, factory style axles, mounts, shift linkages, and gearbox sensors can economically remain intact.

Strength of the individual gears is also a big plus. Unlike their B-series bretheren, D-based gears are "stubby", and take well to abuse. Favorite transboxes include, but not limited to, the '86 to '89 Acura Integra D16A1, and the '97+ Civic ex (due to the ferrous based shiftforks)."

 

Yup you dont need a press to take off the gears or the synchro hubs. A rubber mallet helps though.

 

Is it true the zc transmission is the strongest for the ef chasis(d-series that is)

 

If I can do it most trained apes could

those who've seen me shirtless can mistake me for a trained ape

Well, I don't know about that. Just because Bisi says something, that doesn't make it gospel. After all, he IS trying to sell a product here. But if that's what he likes, then he is free to say what he wants. I just find this extremely fishy for several reasons. First of all, nobody uses D-series transmissions who doesn't have to. And this includes people with 600+HP turbo setups. If D-series transmissions are so much stronger, then why are they not in widespread use among people with high HP setups? It's not like they are expensive. And secondly, how do you fit bigger, stronger gears into a smaller and lighter case? And why would Honda make transmissions this way? As for failures of B-series transmissions, I have NEVER heard of B-series transmissions blowing up. The synchros do tend to go bad (as they do on D-series transmissions). But that's about it.

 

Matt,
I have access to both D and B transmissions. My all motor drag peers break b trannies with 240whp, and hence have to turn to Liberty, Quaife, Houseman, Gearspeed, etc. to beef them up. We won the 2003 IDRC championships with over 320whp...with ONE factory d-gearbox. The same experiences have been the case on cars I have worked on.

Even though I have the resources to race any Honda base gearbox that I choose, I still use a D16A1 tranny. Why?: because I use what I see as best from a performance, design and cost standpoint...as an engineer, and an enthusiast...not a herd follower.

When you have the opportunity to build and race both D and B transmissions, then you may have a decent debate. It is painfully obvious that the Honda performance community dislikes all SOHC engines...and hence its lack of ubiquitous use: and you know that.

One day, I would like to find out why you are so against my theories and experiences....and why you are so bitter. Nonetheless, have a pleasant day.

dood why rebuild it when u can buy another for 50$.

for the price u pay to rebuild that thing u could have like 6 spares laying around waiting to be bagged and broken.
