(B-Series Gearbox - Gear Ratios and Teeth Count)

*debatable disclaimers
• There is noteable bickering on the net about the S1/J1/Y1 B16 transmission gearing. It mainly revolves around the 5th gear. I find it a waste of time to whine over the 5th gear being too tight or too long of gear. Big deal - it's only 5th gear! My tranny specs were gathered from the Revspeed civic/integra bible(s).

The 4.266 final drive is a debatable spec. If you look in a Helms manual for the 99+ Si Coupe, you will see that 4.266 is the final drive spec. Eddy Lin has found that to be false - he physically took a 99+ Si tranny apart and counted the final drive teeth which calculated to a 4.40 final drive ratio. So, yeah..it's debatable, but I believe it to be a 4.40, even though the Helms manual could be (and probably is) wrong.

• According to my resources, the Y1 + YS1 cable tranny's, are the only two that came with optional LSD's in Japan.

• There's a debate over the 5th gear ratio, in the J1 transmission. Whether or not it's a shorter or longer ratio gear. I personally don't care, but what I have up on here is what I believe it is, and what I've learned from my sources..
Not that it's a big deal or anything....

• US market did not receive any LSD equipped cable tranny's.

• ANY B-series tranny (cable & hydro) will mate up to ANY B-series engine block: B16A/B17A/B18C1+5/B18A+B/B20.
Just make sure that you use the correct clutch, flywheel, & intermediate shaft when mating the trans.

• Lastly, a lot of people think that you can tell a tranny's gear ratio by the tranny code, which is false!.

• The tranny code ONLY tells you what chassis the tranny orginally came from - not what gears are inside of it.
