Honda Manual Transmission Specifications & Gear Ratios

CIVIC (Fourth-Seventh Generation), FIT (First & Second Generation), and INSIGHT (First Generation).

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.





CIVIC (FOURTH GENERATION)
Year & trim levelOEM engine codeVSS / Speedo gearOEM wheel / tire1st Gear2nd3rd4th5thReverseFinal Drive
1988-1991 Civic base modelD15B11,026rpm VSS cable = 60mph155/80-R133.2501.6501.0330.823-3.1533.888

88-91 Civic Si / CRX SiD16A61,026rpm VSS cable = 60mph185/60-R143.2501.894 1.2590.9370.7713.1534.250
88-91 CRX HFD15B6 1,026rpm VSS cable = 60mph165/70-R133.2501.6501.0330.8230.6943.1532.95/3.250 (CA)
Notes: Trans code for all trim levels is L3 (use this for parts and specs ID). 4th gen Civic trannys have cable clutches, but they can be modified to fit the later Civic shifters. One EM member successfully swapped an HF trans onto a fifth gen (VX) engine in his 4th gen Civic body. But the mount for the transmission changed after the fourth generation, so while a fifth/fourth gen engine/trans combination fits into a fourth gen car, the transmission mount would have to be fabricated for that same pair to fit into later Civics. The HF transmission--and maybe the others--had a shorter counter shaft and a different ring gear than the 92-00 Civics.
There was also a JDM DOHC CRX with shorter gearing than any of these listed here.
Honda used white big bore (40mm) speedo gear in the 88-89 transmissions, but also a few have shown up in 96-00 EX transmissions.





CIVIC (FIFTH GENERATION)

Notes: Trans code S20 on sticker (P20 stamped on housing).
All have hydraulic clutches.
All 1992-2000 trans have one of two speedo gears: EX/Si/HX use “big bore” black one and others use white one but outer diameter is the same. Honda had used white big bore (40mm) speedo gear in the 88-89 transmissions and a few have shown up in 96-00 EX transmissions.
IDENTIFICATION: Look at the fill plug for a circle cast into the housing.
P20-A000 = DX, CX, VX trans & P20-B000 = Si, EX trans.
To ID use gear ratio test in sixth gen next note below.

Notes: Trans case code S40 (on white sticker, used for parts ID).
All sixth gen Civics had hydraulic clutches.
All 1992-2000 trans have one of two speedo gears: EX/Si/HX use “big bore” black one and others use white one but outer diameter is the same. Honda had used white big bore (40mm) speedo gear in the 88-89 transmissions and a few have shown up in 96-00 EX transmissions. A previous version of this post listed a 96-00 HB EX with FD 4.058 but it seems not to have been sold in the USDM.
IDENTIFYING RATIOS (Example 3.722 final drive). Get an old clutch, mark it, & place the mark at noon. Select 4th gear (0.909). Mark differential. 3.722 * 0.909 = 3.38, so clutch should do 3.38 revs for one rev of differential & clutch stopping 4 o’clock.

Notes: The EX final drive ratio is listed at honda.com with both the 4.111 final drive and 4.412 final drive, depending on which year one checks. All seventh gen Civics had hydraulic clutches, but with cable shifters instead of the shift rods the fifth and sixth gen models had.
Trans case code SLW on sticker PLW on metal (Hybrid trans code SZB).
Successfully swapping seventh gen (2001-2005) civic engine or trans onto a fifth/sixth gen engine or trans is possible but complicated by the differences in shifters and the seventh gen Civic's immobilizer. Wiring and shifter adaptation might be required.

Thanks for the info California98Civic.
So now I need to look for a 88-91 CRX HF D15B6 5 speed transmission ...
I read that the 88 has different spline, so it would need a matching clutch.
Other years match the VX clutch.
The difference in gearing would make 5th gear at 1700 RPM doing close to 56 vs the current 1900 RPM at close to 56.
That should pay for itself pretty fast as I currently get approx. 80-95 MPG at 56.
I see a few on CL in the USA, but none in Canada yet, but I will be searching.

If that chance does not emerge because of costs related to getting both the trans in good condition and a clutch you could also look into whether the 4th gen HF final drive can swap into the fifth gen VX tranny. Now that I know the VSS gears in the 4th and fifth gen spin the same, I would bet the speedo gears are the same too, as they are for fifth and sixth gen Civics. Since the Cali HF trannys had the same final drive as the VX, I wonder if the 2.95 final drive from the VX would swap. That would give you nearly all of the RPM change you describe. It would be a bigger job maybe, but could be interesting too.

A quick google got me this answer ..
The Ring gear is the same but the countershafts are different. The 88-91 HF C/S is shorter than the 92-95 VX and has a shorter bearing section for the 1st gear.

Thanks. I found that opinion on honda-tech just now, following your lead. Synchrotech is an excellent authority, so I edited the OP.

Jeez, just look at what they've been doing to the Fit M/T!

Top gear ratio just gets worse and worse from 2007.

Really?!! I didn't realize they further shortened the final drive in the '12 model Fit. Makes sense (in the weird honda engineer world) because they added some sound-proofing weight.

For the record, the 1st gen Fit went from 2002(3?) to 2008, but was only here in the USA for 07-08. '12 is a cosmetic makeover of the 2nd gen which started in 09.

Yep. The gear ratios are bad. It's amazing what you can overcome with pulse & glide, though.

Right? Makes you wonder what can be done with custom gearing or better yet whether 1990s gears, any of them, might be adaptable, swappable.

Amazing to see it tabulated like this, huh? Brings clarity. But if you could combined the 07/08 FD with the 09-present fifth gear, you'd be close to a 1990s Civic DX (but not quite there).

Do you have a citation? Because when I looked into it, I found claims that the 07 model year introduced here in late '06 is regarded as second generation. I don't really believe that, and my gut agrees with you, but I saw not evidence other than how I might interpret the apparent changes in the gearing.

Quickest source I could find was wikipedia.

Although the second generation Honda Fit was introduced in the Japanese market in 2007, the first generation Fit was still sold in the North American market for the 2008 model year. The second generation Fit for the North American market was unveiled on 19 March 2008, at the 2008 New York International Auto Show for the 2009 model year.
Oh, and the 1st generation engine is coded L15A1. It's a 2-stage i-VTEC with max 109 hp. The 2nd generation's L15A7 engine gets a 3-stage i-VTEC that boosts top power to 117 hp. (yay?)

I confirmed your gear ratio chart, though. They DID change the final drive for the 2012 mid-cycle refresh. (4.62 to 4.625)

Oh, and for the D-series transmissions, couldn't they stamp a different code on them? Why mark all the different ratio transmissions with the same code? Grrrr.
