Has anyone tried to swap the transmission from an auto to a manual? If so what trans and mounts do you use? Just curious because my Honda doesn’t feel like it has much life left and I’d like to swap out the transmission if and when I pull the motor for a refresh.

Unless you want to put a lot of time and effort in to it, it's not worth it. (If it's even possible) You will need a computer for a manual-transmission car, and maybe a wiring harness too.

The days of swapping autos for manuals are pretty much over.

Selling your auto and getting a manual is the easier and likely cheaper in a long run.

I can see why people want to do a manual swap on a V6 Sedan since V6 MT Sedan is a combination that isn't available from the factory. I4 Sedan MT is a stock combination possible from the factory(I have one right now), so seeking out one is a better bet.

Welcome!

Has anyone tried to swap the transmission from an auto to a manual?

Yes, plenty of threads here if you search.

If so what trans and mounts do you use?

No clue, they never got that far.

Thanks for the quick reply everyone. I see that’s the coupe comes in a manual but I have the sedan and was wondering if that trans was interchangeable. I know it’ll more than likely be more expensive than it’s worth but I’ll probably be getting a new car soon and that will be the back up.

I4(K24) Sedans also come with a manual trans option from the factory. It's the V6(J35) Sedans that lack a manual trans option from the factory.

I4 Sedan and I4 Coupe share the same manual transmission. Powertrain-wise they are very similar as long as you are comparing them to the same trim.

Not trying to revive an old thread but just so you all know, we manual swapped 8th gens exist. It was worth it for me. Anyone wanna know the how too can just ask. its kind of the same as any other k auto to manual swap. Just different parts.. obviously

Was it the 5MT that came from the factory? I been thinking about doing the 6MT swap from the 2nd gen TSX, ILX, or 9th gen Si.

I'm using a factory 5 speed out of a sedan (same oem P/N). I went 5 because I wanna k24a swap this thing and throw boost at it plus I'm under the illusion a sedan is less likely to be abused than one out of a CS1. For my own reasons I didn't go 6 speed. But 6 speed off rip puts you pretty close to a factory type s stock for stock. (Did some pulls with a friend to see differences, gearing plays a huge role but in the high end its not too bad. Its on the shifts that's where they get you 7.5 to 5k rpm drop. This was tested with a k20z1, not a2. Mentioned this because the z1 has about 11 more horsies) that being said there is a big advantage to the 6 speed if all motor and with a few bolt ons you can be faster than a 6-6 tbh. Lighter. Better sounding. DOHC Vtec. ;]
Now the only downside is that the factory ecu and harness does not support a reverse lockout for 6 speeds since the 5 speed lockout is mechanical not electrical. But if youre asking if it bolts up, yes 100%. These transmissions use the same casings. мillмаsт on YouTube confirmed this by swapped an si tranny into his 8th gen.
If you want tips I'm an open book. Just gotta ask. I been lurking forums seeing Rick Blaine poop on everyone lol but I figured if I did it ill bring hope to the 8th gen community. It's not hard. Only fabbing was on the pedal (cutting the firewall for the cmc) and mounting the pedal right
But I will say this, I haven't gotten the electronics sorted out because I'm still using an automatic ecu. I swapped mine like last week and it took me a week working with a full schedule. Just slowed down once the car started moving under its own power. Waiting on my ktuned hydraulic kit (cmc and slave). Oem remanned one I have has issues moving the dense ass exedy stage 2 pressure plate.

My additional reasons for doing this was my tranny was going and I had leaks everywhere on the motor so I could've either went to a dealer and paid 5k. Swap in another auto to go out in another 50k miles. Or spend less learn through research as this is my first manual swap and this story has a happy ending =] also resealed my motor. Pretty much learned on the fly. Saying this again because its really NOT as hard as everyone says.

If you wanna know how to do this I'll detail a guide for the ins and outs. There are some things not required but recommended heavily and usually already had by anyone willing to mess with their car. Seeing youre turbo you probably already have it.
Some may say its dumb to do but hey I was smart enough to figure out what they said was impossible and to be quite honest this was the first time I've even pulled a drivetrain. Not the first time I've disassembled components and reassembled them though. Its not really different from a base rsx manual swap (easier actually) or 7th gen accord swap.
And before anyone asks. Like all the other gens who went from auto to manual. Yes I would do it again next time I'd like to see an encouraging post rather than a "no dont do it youre incapable"
Can post pics if any of you need for proof. Got one here but didn't take any with it in the car yet since I haven't buttoned it all up yet
There's more manual swapped i4 8ths out there. They're just lurking like me

A lot of the skeptism from the forum comes from the fact that, well, it's a general Accord and most people just treat them like family cars. A family car they care about, but a family car nevertheless, not a performance machine.

That, and a lot of swaps do go sideways. People dream big and sometimes they just can't match their words.

Either way, I personally would jump at a 6-speed without any doubt. The gear ratios in the 5-speed aren't great at all, with a very tall 2nd gear that can hit around 70 MPH in 2nd. A rule of thumb for me is that anything that's not above a turbo 6-cylinder or NA V8 should never have a second gear that goes past 60 MPH. I guess with boost though, it may have less impact. You sound like you have an idea what you are doing, so keep at it!

I understand your viewpoint 100% I love my family coupe and I appreciate your attitude. You're right with the gearing being more economical. Much respect and thanks for the support 🙏

@Pearl coupe do you mind potentially writing a dedicated thread on your swap?
Also, do you know if the K24A and K24Z transmissions have the same bell housing and are interchangeable? I have a few ideas in my head about what I want to do in the distant future.

 

[Pearl coupe]

Will do. I'll link it to here when I finally do it. I'll need a few days when I can sit and do it. I may end up doing it tonight tbh. I will be very detailed about this way to do it. I'm still running a full automatic electronic system and it runs fine. No vtec at the moment thought. Fixing that on sunday, hopefully. Will edit the thread when I figure it out. I plan on changing a lot electrically. I've been driving the car everywhere with no mechanical issues. Electrical as is isn't that bad right now tbh but I want 2step for when I decide to turbo this. To answer your transmission question. This is what I've heard. The A trans can be swapped into our cars (we use one less mount than them). Apparently there's a CS1 thats in Japan drifting with an awd crv trans. Cant confirm but this is what I've heard from multiple sources. So its probably possible but I'm not sure how it goes to mounting our lower tranz mount since I haven't seen an A trans to compare everything yet. I've looked at pics but a tangible trans is better. Actually. Ill look at my buddies type S to give a definite answer soon enough. Now if you go with an A trans you'll have to figure out shift cables and gearbox because (this is what i know) the OUTER casing is different and so is the gear select mechanism. You MAY be able to use your stock cables but you CANT use our stock gearbox. But it will bolt up to the engine no problem. The most important mount is the top mount and all K series transmissions (even a type R) have this mount its the upper trans mount. Honda has really good geometry making sure their K series engines and trans orient themselves similar across their 2000-2016 k cars. So easy answer - Yes their interchangeable but you must adapt the shift mechanism to your vehicle and make sure the lower mount is good. I rode without the lower mount and stress tested it. The mount really just reduces wheel hop under load.

Sorry to spam but I actually looked harder lol. Seems like the shift mechanism is different and we just use one less mount somewhere. So yes an A trans will bolt in. Just different gearbox and potentially cables. Stock mounts will fit. BUT depending on which A transmission you get. You may have to find an upper trans mount nut. Some of these transmissions have an integrated stud. Wish I got an A trans now lol. Short shifters are amiss for the Z trans (except si 🙄)

A/T to M/T swap GUIDE

As the title says this is a guide, not a question so if you're looking to shut it down, keep reading. Backstory - Some bearing in my automatic transmission somewhere was rattling or something so instead of spending the 3k somewhere to rebuild it since I don't know anything about an automatic...

www.driveaccord.net

Hudoc, you being boosted and looking for a 6 speed should take a step further and look into better synchros for whatever transmission you get, ilx, TSX, or si. Off rip, you can probably throw another lb or 2 of boost at your setup but the trans will still be the weaker link, assuming the engine is properly maintained with no issues. From a performance perspective, honda guys opt for 5 speeds mainly because its fewer parts and they're less likely to break, however, the 6 speed does have better gears for an all motor setup. Just my 2cents.

what will i need to swap it besides tranny? i have a cool ass 09 accord but its auto i want to do the 5 speed instead

How has your manual swap held up? I love my 12' Accord but it's also auto. I'm on the fence about swapping to manual. Especially if I could use an K24a2 or SI transmission.
