You should easily find a used transmission on craigslist for around $250. If you know its the input shaft bearing, replacement is relatively simple and the part is cheap. There are guides on the Honda forums for the replacement procedure.

What cbaber says in above reply and Car-Part.com--Used Auto Parts Market ... that's where I got my 1993 CX trans with 93K miles for $300. I had been watching for quite a while, but I just checked for VX trannys in the Southeast and see a few listed as "A" grade in GA and FL for under $400 ... there was one really good looking one with a very low price and very low miles in VA.

Good luck.

Thanks for the info. I'm pursuing a lead on craigslist for a used EX coupe transmission with 58k miles right now which should have the same 4.058 final drive as my DX sedan. I'd love to get a CX transmission in the car but unfortunately I am moving in 2 weeks, I have to pack up my house and this is my only car so I’m bumming rides off my friends until I can get this taken care of. Gear ratios aren’t bad as I’m around 3250 rpm at 80 mph so I’ll just have to take what I can get. Thanks to this thread I know what models to look for. And thanks for the help guys. I really appreciate it.

I'm sorry I didn't see this sooner. Thanks for posting it!

Wow, the gears on my HCH are tall; only the Insight is taller. And with the super-dinky little 1.3, it's just ticking over at about 2100-2200rpm @ 60. If it weren't for the IMA, the 0-60 time would be measured with a calendar.

Ok, so the obvious question is, how does one get a hold of an HF 5th gear, and which transmissions will it swap to? I have a spare DX hydro trans I'd like to build up.

(Thanks for the info by the way!)

Here is an example of my 89 dx tranny on my d15z1 motor in my 89 dx sedan. at 77 mph at top dead center i heard is how you can tell what tranny you have. Err final drive. Its at 3400ish rpm. I swapped in my Hf the next day and at 77mph it drop it down to 2300.

Here is my picture of the final drive of a 1991 crx hf. 65 teeth, and 22 teeth on the pinion gear. I pick the tranny up from pick n pull a month and a half ago. Drop it off at the mechanic. Rebuilt it with Honda OEM parts for $190 bearing kit and he check the syncros. Here is my 91 HF mated to my 93 d15z1 in my 89 civic sedan dx.

All info is for the US domestic market unless otherwise noted, such as "JDM" (Japanese Domestic Market). I will edit, correct, and expand this information when I can. If I made errors let me know. See sources note at end of post.

What a great collection of info! There needs to be a 10X-thanks for posts like this. Separately, I wish top gear ratio was commonly listed along with engine displacement.

In particular I've been wondering what I would need to do to get a taller gear in the 97. Funny, the car is badged as LX (and has the OEM A/C), but the drivetrain is EX: D16Y8 and 4.25 (3000 RPM @ 70 MPH). No wonder I felt like I was driving the shortest Civic gears available: I am (but not as short as the 89 Corolla). I can confirm P&G/EOC works wonders, and for a 5MPH spread I'd guess it's only a few dozen feet of dithering, so unlike some others I don't feel like it's a big deal in moderate traffic, love my killswitch, but there is still a lot to be said for taller gears.

So now I just need to figure out if the 92-95 VX/CX final drive can swap into my tranny, or else presumably I need to follow car-part.com for the whole tranny and plan a full swap. ... probably just going to wait until the original clutch eventually gives up though, get those things done together.

Glad you find it useful! I actually have a VX final drive gear and countershaft I have long thought i would swap into my 98 DX transmission as part of a general rebuild. I'm told it should work. I think putting into an EX transmision would be even better because lower gears are much shorter thanin the VX, while 5th gear is about the same. I suspect my 93 CX trans is not as good in the city as my98 DX trans was, because the gearing is so tall,especially the transition from 2cd to 3rd, but also first.

No one has successfully swapped a seventh gen (2001-2005) civic trans onto a fifth/sixth gen engine, or earlier trans onto seventh gen engine.

Wrong.

D17A2 in a '95 Civic using D16 tranny

There is very little reason to do this swap, so very few people do it. Shift linkages are very different (cables vs. rods), so you can't easily swap one to the other. But, if you try putting a D16 in a 7th gen Civic or a D17 in a 6th gen Civic, the engines and tranny will bolt up fine.

There's a lot of misinformation on this out there, so it's hard to find out the details. The link above includes pictures of the D17 with a D16 tranny.
