Wow glad to hear the issue was found , everyone should definately keep this fresh in your memory. If it happens to you this info will save tons of headache.

When I took my car out and broke 2nd gear, my car shut off as well similar to how yours did. I raped 2nd clean off and it broke my sensor as well. Although I did not have a shorting issue.

I'm not sure if it was shorting or not. You may have not had ecu problems like me because you have an older ecu. In the 8th civic it turns out if you have like any random fuse blown or unhooked you can't detect the ecu. That to me is crazy! I understand not starting or something, but literally having no communication what so ever with the ecu is pretty nuts.

Pretty crazy a trans problem made it impossible for me to communicate with the ecu! O well at least we are on our way to actually fixing it, rather than just scratching our heads. Does suck though as this couldn't have happened at a worse time.

Yea deff glad you guys got it worked out and arr fixing it now vs diagnosis still

I don't know why so many ppl have problems with them trannys I and my 5 speed have been holding up since 2010 of being boosted...

Ppl give up testicles to have your trans, speaking of which, need a couple?

Got this pic earlier today


I kinda wanna get an ep3 5 speed gear set have it shot peened and put that in, but I'm not sure if I will have enough time for that. Maybe that can be a summe project and for now I just get the car running.

Thats a good looking 2nd gear you have there. Did it break any teeth off of the gear on the countershsft or just the main?

Glad you guys figured it out. And Id definitely say this is definitely a one-in-a-million type thing, and it happened to [MENTION=56]Adm_rsx[/MENTION] too! Hope things end up smooth in terms of the next three weeks for you. School comes first though, you can't let your grades slip because of your car. Good luck

I think the counter is ok. But I didn't take this picture nor have I seen it in person. Hopefully will know some more today.

Ya unfortunately the timing of this was horrible. I would have really liked to have done this myself to learn something new but I need to finish school and being I want to go to law school I have to get all As. I also need the car fixed by the end of school so it just didn't add up for me to do this

Bringing some good discussion over from 8th.

yes sir! RSX Base and the EP3 both use the K20a3 so the same trans as well.

why dont u just replace 2nd gear and call it a day?

Well second gear is like $300.

He didn't break just "2nd gear" The mainshaft needs replaced. 2nd gear doesn't come off of the mainshaft its one solid piece.

I thought second was on the counter shaft? I really don't understand it though.
Honda Automotive Parts

which includes the gear right? since its one peice? it looked like just the gear was damaged in the picture doe.

but either way 180 is still cheaper. id just do that.

I don't think the shafts include any gears.

Here are some charts I made up. Ryan the rsx base and ep3 are ALMOST the same but slightly different ratios for 1st and 2nd and the rsx using a 4.7 fd and the ep3 is a 4.3 fd. I think either one would work fine, but I would use the 4.7 for both. I would not want the 4.3 that comes in the ep3 as the gears are just a bit too long for my needs. Hell even with the 4.7 they are pretty damn long.

Here is the rsx base with our fd (would reuse that from my case probably) next to our stock transmission (this one and the next are very very similar)

Here is the ep3 trans with its stock 4.7 fd next to our stock trans

And here is the rsx trans with its stock 4.3 fd next to our stock trans (way too long imo, I def do not need 4th to go to 150+)


LMK what you guys think!

This is our trans with 4.3 fd. These are some nice ratios, but I need to consider the cost as well. The rsx trans is much cheaper.

There is a gear for 1-6 on both the main shaft and countershaft. They mesh together. The mainshaft is spun by the engine, it transfers that energy to the countershaft which spins the final drive spinning the Axles.

You broke the mainshaft 2nd, which doesn't come off.

Id do the RSX or EP3 with the 4.7FD or a 6sp with the 4.3...its a pretty good setup just bogs a bit if your really low in the rpm range in 6th.

id go with the mainshaft. with an ep3 5 speed, i think its just gonna hurt his acceleration unless hes makin big power like you. idk what his goals are, but id stick with stock ratios. just pay 180 and be done with it and drive the car

300wtq is enough for a 4.388 fd or RSX/ EP3 base trans in my opinion, The stock gearing is pretty short for 400hp, you bang through gears quite quickly. It will help a tad for traction, and give him more time between shifts. It will reduce his acceleration a bit, but not enough that it will feel slow

Can I attach my 6th gear to the rsx/ep3 gears? I'm not sure how that works. And thanks for clearing up the mainshaft/countershaft thing. Would probably make a lot more sense if I could see it in person.

Ya I agree with you to a point, but I intend to be around 420-450whp and that's good power, with gears this long and a 4psi wastegate spring I may not have many issues with traction, and I don't think it would slow the car down much, but I will speak with Bill about it as he at one point put the 5 speed in his rsx. And yes I can just get the mainshaft for 180, but other gears appear to be damaged just looking at the picture so if others are somewhat damaged it may not be a bad thing to replace them. Although I may consider just doing a quick for for now and doing something different for the trans in the summer with some shot peening and what not, just not sure if I have the time to get gears shot peened right now.

Yeah the mainshaft 2nd is built into the mainshaft. if counter 2nd gear is fine then all you need is the mainshaft.


Don't you have to redrill for our speed sensor if you use the A2 and Ep3 tranny? Or can you just swap cases?

Yea you do need to do some whacky stuff to use their case, but you can just put their gears in our case and not have to do any of that.

This picture helped me clear some things up when I was doing research.
