How Honda Transmisions Are Geared

[GasSavers_Ryland]

I haven't found all the numbers for all honda civic transmisions, but I do have specs for the 92-95 from the factory shop manual, along with specs for 1983 Civics.
CX and VX:
1st 3.250
2nd 1.761
3rd 1.066
4th 0.852
5th 0.702
Reverse 3.153
Final Reduction 3.250

DX:
1st 3.250
2nd 1.761
3rd 1.172
4th 0.909
5th 0.702
Final Reduction (3 door) 3.888, (4 door) 4.058

SI:
1st 3.250
2nd 1.900
3rd 1.250
4th 0.909
5th 0.702
Final Reduction 4.250

My 1983 Civic factory shop manual lists:

1.3L base modle hatch back:
1st 3.272
2nd 1.666
3rd 1.041
4th 0.777
Reverse 2.916
Final Reduction 4.066

1.3L FE hatch back:
1st 3.272
2nd 1.666
3rd 1.041
4th 0.777
5th 0.655
Reverse 2.916
Final Reduction 3.722



1.5L Wagon, Sedan and DX Hatch back:
1st 3.181
2nd 1.823
3rd 1.181
4th 0.846
5th 0.714
Reverse 2.916
Final Reduction (Wagon, Sedan) 4.266 (DX hatch back) 3.875

so as you can see, at least for the 92-95 modles, 5th gear is only higher because of the final drive.
Now the Automatic in the SI and the DX is exactly the same acrose all the gears, and the final drive.

If anyone has simaler specs for 1984-87 and 1988-91 modles I think it would be interesting to see how they all compare.
