No you need to swap the ECM. The ECM is made for an Auto tranny. It is NOT WORTH it to swap transmissions. Either trade your car for a manual or don't bother. There are tons of threads on this subject.

hey,
how much will the conversion cost, I have an auto also and I'm going to do my swap in May. The shop gave me an estimate of 1600 dollars.

I'm doing the same thing coming up in, maybe 2 - 4 months tops. Just gonna buy one outta a junk yard for cheap hopefully and have a buddy install it!

 

yeah you do need to swap the ECM, totally different on MT....be careful though i had a friend who swapped out his accord auto for a m/t and it totally screwed his car up.

i have a shop that can do it for me for $2000 cdn that's not including the ecu..... but i was wondering if i am able to run wif the auto ecu for now and change it in the future.. cause i remember i saw a post before made by elite by i can't find it now..

hmmm ... totally forgot that you had to swap the ecu too !! DOH !

 
Rep Power: 0

But i've read the post elite post before he said he still use the auto ecu
and he said the engine light was on.... but i was wondering if it was ok like that

because the AUTO has one more extra harness that plugs into the ecu. All you have to do is unplug it and it will throw a cell. But I think you can still run it that way...correct me if I am wrong.

here is a list of crap you need for the 5-speed swap:

M/T Tranny mounts
Tranny
Clutch Master Cylinder
M/T Slave Cylinder
Clutch
Flywheel
Dash Wire harness for a M/T
Engine Wire harness for a M/T (I have extra if anyone needs any)
Subframe
Axels for a M/T
ECU
Shift Linkage
Shifter Assembly
shift ****
need to get your key reflashed for the new ecu that also has to be flashed


I am thinking about selling mine it has everything for the swap ready for around $2000

wouldnt it be cheaper for the boosted people who's planning on doing a tranny swap to just get a used d17 engine with manual tranny for $400-500 and buy the other mics parts that way u have an engine u can send out to get sleeved and then put everything in .. reducing the down time of having to yank ur current engine out and send it or is it just a waste of money?

good luck trying to find pedals and clutch master cylinder and a dash harness uncut along with a subframe and axels.

I am going to do this swap hopefully on monday if the shop that is doing it for me can find all the parts.... the only i was worried was the ecu

i want an 5 speed so bad

i was thinking about doing the swap also, but instead of taking all the time and money for the d17 5spd im just gonna wait it out until i get enough cash for the k20 swap, cause ill just put the 6 spd in then. itll be a lot longer wait but i think it would be worth it. cause doing the tranny swap now in our cars would just be pointless. but thats just my opinion

I'm not sure if this applies to 7th gens but when we did an auto to manual conversion on an older accord we had to use a manual ECM. I think it had something to do with the ECM thinking the car was in park.

 
Rep Power: 335

i do think our cars wit the automatic makes it lack in many places, its all top end. but the acceleration sucks nuts. all my friends beat me off the line. but at the top of 2nd gear im pullin hard on em and 3rd gear is when im passin ppl and from there its anybodys game lol

You seem to be under the impression that the 5 speed civics are fast. Although they are faster than the automatics...I assure you you wont be keeping up with any fast cars even with a 5 speed. By the way...what the hell are you racing that you're taking them in an auo civic?

I personally don't think this is a good swap. Your paying 2000 dollars for something that you could have had from the dealer and actually paid LESS for your car. So you pay like 800 from the dealer for an auto tranny when you first buy the car...then you're going to pay 2000 to remove it and put in a 5 speed? OK...it's your money. I just think it could be better spent. For 3000 you could have a turbo. Just my opinion though.

My friend has a 99 civic (auto --> manual conversion) and he's running off the auto ECM. It idles weird, but that's about it. He's waiting to get his computer reflashed or something from hondata before he switches over to a manual ECM.

So you could probably run a manual off of an auto ecu, with maybe a CEL, but maybe not even that.. Like I said the only thing I know of is idle is screwed up a little.

i have an 02 civic ex coupe thats auto and i blew the tranny at 38k miles... and just dropped ina jdm k20 with 6spd LSD... just gotta figure out the wiring...

 
Rep Power: 0

it's not worth the trouble to do a manual conversion when there are plenty of manual cars to be found..... so sell the auto & buy a manual...

aside from that if u do decide to convert to manual and ECU change is a must....

 
Rep Power: 0

well if the car was stock then i could understand your reasoning, but i have alot of money invested in the car, fiberglass in truck and back seats... ps2... so its not that much of a pain.... i had to buy shift linkage for the tranny, the gear selector for the manual shifter, a new brake pedal and clutch pedal assembly and i am getting the new ecu with the engine/tranny i bought.... so it should go well,. but obviously, EVERYTHING is a project....

Good luck with it man, I did an auto to manual swap in my Mustang and it wasn't tough if you have a clue what you're doing... Then again, Civic's are a BIT different...
