K-Series Transmission Table

[Tnhatch03]

Thank you K20a.org!

Here is a table i put together of all the transmission gear ratios in all the cars i could find published data for.
If anyone finds published data on the CTR please let me know so i can add it to the chart.

If anyone has the tranny codes of the engines listed below, please let me know so that i can add that info to the table. Please be model specific with the tranny codes so that we can see if some models use same exact tranny etc.

All my info is from honda.co.jp, acura.com, new-cars.com.

I noticed Acura.com rounds up when i compared to ratios found on honda.co.jp. (Example: 1st gear is 3.27 instead of 3.266.)

Tranny notes i have put together:
1) 01-06 accord euro-r and 05-06 rsx-s have same tranny.
2) 01-06 itr has the same 1-3 gear ratios as the 02-06 rsx-s, euro-r, and 06 si but has different 4-6 gear ratios.
3) K20A2, K20A euro-r, K20Z1 all have the same 1-6 gear ratios.
4) all 6-speed tranny's except 02-04 rsx-s & 06+ CTR, have the same 4.764 FD.
5) 06 si and 04-06 tsx have same 6th gear.
