Ok I got this transmission in an S1 case was told it was a B16 S1 so had it apart just checking the synchros and decided to count the teeth to figure the gear ratios.
Got the gear ratios from here: http://www.allmotorhonda.com/t...s.htm

Gear ---- Main Shaft Teeth---- Counter Shaft Teeth ---- Gear Ratios
1st---- -- 12 ---- ---- 39 ---- ---- 3.25
2nd---- -- 19 ---- ---- 39 ---- ---- 2.05
3rd ---- -- 24 ---- ----- 34 ---- ----- 1.41
4th ---- --29 ---- ----- 32 ---- ----- 1.10
5th ---- -- 32 ---- ---- 29 ---- ---- 0.90

First Gear looks correct but the remain are closer to a Y1. Can anyone verify this isn't a part/pieced together tranny or know where I can find the correct number of teeth for each gear.
Any help you can offer would be greatly appreciated.
Thanks

looks like you're 1 tooth off in counting

countershaft 2nd should have 40
40/19 = 2.1052631578947368421052631578947
35/24 = 1.4583333333333333333333333333333
31/28 = 1.1071428571428571428571428571429
28/33 = 0.848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 84848484848484848484848484848484848484848484848484 8484848484848484848484848484 IT NEVER ENDS!!!!

I swear its 39. I counted them all 2 times prior to posting and then 2nd gear 2 more times after reading the reply. I marked the first one then counted 13 and added 2 more marks and finished on the one I started with, now I'm really cornfused

Any one know what is wrong here??

I believe this is the gearing for the S1 tranny !
3.230
2.105
1.458
1.107
0.848
3.000
4.400

right I have the correct gear ratios listed in the orginal post but I was wondering about the gears teeth count. I've counted numerious times and the gear ratios aren't matching anything ratio wise

zCivic, I have checked a jdm s1 and J1 and they both had the same numbers you got.


*EDIT. this is the only place I have found the correct gear ratio as I have found: http://www.autocrossing.com/cgi-bin/gearcalc.cgi

So I do have an JDM S1 tranny and I'm not going crazy on the gear teeth count, whew Thanks a ton!!!
