  • 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.

ALL KSERIES BELL HOUSINGS ARE THE SAME EXCLUDING THE 2WD AND 4WD
A 5 SPEED INPUT SHAFT AND A 6 SPEED INPUT SHAFT ARE THE SAME WITH THE EXCEPTION OF SPACERS TO MAKE UP FOR THE LACK OF 6TH GEAR
MOST GEARS, IF NOT ALL GEARS ARE INTERCHANGABLE WITHIN THE TRANSMISSIONS HAVING THE SAME FINAL DRIVE.

Im a 03 honda civic si owner and I have broken my main shaft low and 3rd gear. I’m still able to purchase the main shaft and 3rd gear but Honda has chosen to discontinued the low gear for what I do not know. I would like to rebuild because I already spent money on new carbon synchros thinking that was the problem come to find out when I opened the tranny it was my gears. Does anyone know any alternatives for part number 23421-PNR-000 suggestions? Thanks.
