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.

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.
