well my tranny is shot, 2nd gear broke most of the teeth off the main shaft. 4th is close to gone & I figured I replace them all

I have a friend who has a bunch of gears in good shape, but they are either '06 si, tsx, rsx (all mixed) I like to compose a list of gears & list the correct number of teeth for each gear. If any one has any of this info - I'd really appreciate it.

I am planning on a tsx 1st & 2nd, with rsx-s 3rd, 4th, 5th, 6th & 4.7 final drive

I will update this thread as I gather info

Type S Trans Teeth Count (edited for consistency):

Counter Shaft-Main Shaft
1st gear : 49-15
2nd gear: 49-23
3rd gear: 44-29
4th gear: 39-34
5th gear: 34-38
6th gear: 31-42
some have already been posted already, but here are the ones for my car. pretty much the same as the RSX-S.

If I went to the scrap yard with all of my broken gears I would be a rich man LOL.

Tim and I have shelves of gears from all of the gearsets we bought over the year haha. The only way we know which ones are which is to count the teeth. lol

I searched too, but everything seemed to be gear ratio discussions without info on number of teeth.

BTW, if you check out the Gear Ratio chart, you can figure out what gears are in the EP3 trans and use the above info for the number of teeth. For a quick sanity check, divide the countershaft teeth by the mainshaft teeth for the ratio.

Also, TSX 3rd gear is 42/31, not 4th, as 6spd_EK listed it in the first post.
