Transmission & Differential - tranny

I just got an engine and 5 speed tranny to replace the one in my 91 civic. The existing one is a 4 speed. Would it be possible to use the 5 speed tranny, and what all is involved in changing it. Is the clutch different?
Thanks in advance

Yes, you can use the 5 speed in place of the stock 4 speed. It doesn't require any kind of conversion or extra parts. Same clutch, same axles, same everything.

Any tranny that fits on a honda civic will fit doesnt matter wat speed 4, 5, or 6

That will make things go alot easier. Thanks

Any tranny that fits on a honda civic will fit doesnt matter wat speed 4, 5, or 6hold on a sec. thats only true between series. a d will fit a d, a b will fit a b, a k will fit a k. and it will only work in a car with the same kind of clutch modulation. cable or hydrolic.

Any tranny that fits on a honda civic will fit doesnt matter wat speed 4, 5, or 6

Yeah. I was going to call him on that too. Any 4G D series tranny will work, NOT any Honda tranny. And 4G's didn't have hydraulic clutches, so you don't have to worry about that.

what all do i need to a 5 speed conversion/ or manual tranny conversion in general. i have a 4th gen...this is what i have gatherd is there anything else?

break and clutch pedal assembly
clutch cable
shift linkage
transmisson
full clutch/ p plate ect.
axels

is there anything else i need?

something easy to overlook, do you have a shifter? if not, look into one froman old prelude. 88 or somewhere thereabout. my friend used to have one in his crx. it was nice, it was shorter than most aftermarket shift throws and had a nice handle. i think it bolted right up with the boot and everything.

cool...u think thats better then like a sk2 short shifter or sumthing of the such?

i liked it.. try to look at one and see if you like it.

iight well help me out here please
i got a 88 civic 5 speed tranny cable transmission for a d series engine.
i want to put in my 91 civic hb i already know i need a 88 clutch for the transmission do i need to change the axles because when i tried to put the 88 civic axles i bought they didnt fit into the connection of the wheel but can i use 91 axles for the 88 tranny? or do i need to do a 88 axle conversion for car please help me out
thanks

hey guys...so far i have got the shift linkage, clutch cable, and pedal assembly to dot he manual tranny conversion on my 91...on question tho...do i have to get the ecu out of a manual tranny car? or will mine work...i noticed on the clutch pedal there is a plug for a sensor what is that?...does anyone know any wiring problems i will have while doing the conversion?

the plug is for the neutral safety switch, so you cant start the car unless the pedal is down. and yeah, you need the manual ecu. not sure about the wiring though.

i asked a guy around here today and he said my ecu will work and that i wouldnyt have to do any extra wiring?....im confuesd

You might want to change the whole engine bay wiring harnes to avoid cutttin any wires to avoid future problems.

what cutting am i gunna have to do?...man im starting to get scared lol....i need to do it tomroow cuz my auto trany is shot and tomorrow is my only day off...the guy i asked said i wouldnt have to change the ecu or do any electrical....he has had 4 crxs so i trusted him but now you guys are telling me that i need all this crap....im scared now...lol...im going to the junk yard in the mornig to take the tranny out of the 4 door...remember i have a 4th gen...cable tranny...do u think i will be able to finish it in one day?...and also when i take the auto shifter out and everythign will it just be the hole for the stick shifter?...will it bolt right there or is the hole bigger on an auto

I !ASUME! that running your stock ecu will work with a manual tranny, BUT you will get codes from the ecu about the tranny(dough) and your engine MIGHT be running in safe mode if there is such a thing on hondas...

yeah, there is.

well than I sure the engine will go into it and it'll feel like driving an underpowered lawn mower:-D

on the dpfi ill bet it sucks, but on my old mpfi d15, it felt about the same, actually, it felt like the power delivery was a lot smoother. i dunno if that meant faster, but i solved that little problem.:D

man i went to the junk yard this morning and found the perfect car with the perfect tranny...i asked the guy with the end loader to lift the car so i could put something under it because it had no wheels and it was on the ground...well he did it and turns out he hit the trranny cracked the bottom of it and it was leaking i thought about it as i took some of the bolts out...then i was like forget it i dont wanna start with something thats already broken....so ill check again next week maybe i can do it next weekend or somthing....we will see....so you guys are saying when i put the tranny in with my old ecu the car is going to run in "safe mode"?...im going to have to figure out what wiring differences there are.

Your best bet is to get the manual trans ecu. Cause automatic transmisions have a lot mor electrical conections on them. I know you cant use a 91 prelude auto ecu in a manual it will not run at all. I would spend the money and get the ecu to avoid a second trip to the junk yard

well suposedly all i need to do is bring the tranny, shift linkage, clutch cable, pedal assembly, clutch, p plate, and flywheel and 400 bucks and this guy will do the ful swap...he said it costs like 350 to get a clutch chaged so he is basicaly doing all the rest for 400...and because i didnt get to do it today and i have no time for the next few weeks and my tranny right now is about shot im thinking about doing it...all i need to get is the tranny, flywheel and clutch, oh yea axels too and hopefuly that wont cost me anymore then 200...the junk yard charges 98 for a tranny and 30 day warrenty..im thinking about just picking up the tranny and full clutch and flywheel and axels an droping everything off and have him do it for 400 what do you guys think? good price or what?

not too bad, but the last time i payed for a clutch job, it was 150. (labor)

true...but you think 400 isnt that bad of a price to do the full conversion?...im gunnahave to spend like an extra 2 on top of that to get the tranny and the clutch and that crap...i got the other stuff free so i gues that would make me 600 into it....if it will hold out till i get time i may just do it when i pull the motor but...we will see...thanks for your imput guys

one more question...will four speed axels fit in the 5 speed tranny...until i have the money to buy the bigger hubs for the 5 speed axels?

They should fit call tour local parts dealer and have them make sure that the part numbers are the same.

i just did my 88 civic two days ago and the info sacicons gives is right on. listen to him!!!!!!!!! i ended up needing clutch flywheel and tranny, even though the bell housing and all looked exact match, also plan to have your flywheel surfaced and take time to install pressure plate correctly if you dont want the clutch to be niosy or slip, criticle to titghten the bolts alternatly and not to much at once or you will warp it, hope it works out for you

Does anybody know if there is anything different with the shift lever to change a 4 speed to a 5 besides the numbers on it?
Thanks

i dont know, but i dont see why there would be.


EDIT: on afterthought, there may be a difference in the shift linkage, but i dont think so, im pretty sure its ALL internal.

and also, whenever you guys figure these things out, make sure you post it so it might help someone else out one day.

I will be sure to let you know if it all fits together right and what we had to do if it doesn't. Just started getting the engine back together, but the weather is looking cold this weekend so getting it back in the car might take me a couple more weeks.
When I changed the axels in my car recently with the 4 speed tranny, there were a couple different sizes. The first size I bought fit the tranny but not the wheels. I haven't tried them on the 5 speed yet, but soon.

i did not have to change levers or linkage the changes are internal

does anyone know if you have to take the whole dash out to change the pedals?...i was thinking about putting the manual pedals in tomorrow so that would make one less thing to do when i get the tranny...when i took the pedals out there was no dash or steering colmn so it was pretty easy but when i look at mine with everything there i dont know if i can do it without removing the dash...also you gus dont think there would be any problem with having the manual pedals in there with an auto still...it would just be that extra pedal that will do nothing till i get it all hooked up.. thanks for any help
