Long story short. I tore up my 4th, countershaft and ring gear. Ordered a full gsr gearset and ring gear from a guy in California. He forgot to send the ring gear so I am using one of my friends gsr ones and giving him mine when it gets here. The ring gear and counter that came out were gsr ones and the new ring gear is for sure a gsr one comparing it to the one that came out. Here is what's happening:

New ring gear, old counter shaft, perfect:


New countershaft, no diff. Again perfect:



New counter (supposed to be gsr) and new ring gear (gsr):



As you can, it will not go down all the way. There is a noticeable gap and it's causing the gearset to bind up. What gives?

 

I think you already know what the issue is. It's clearly not a 4.400 94-01 GSR final drive if it doesn't just drop in. Either that or your friend's 4.400 ring gear is not from a 94-01 GSR. Either or. Though it seems more likely the countershaft is incorrect given your first picture.

p.s. You should be wary of using a non-matched countershaft/ring gear combination.

 

Is there a way to tell what the hell it is then? I counted the teeth and it's the same. Possibly an ls counter?

 

GSR countershaft will have 15 teeth and 3 ID marks. The LS countershaft will have 15 teeth and 2 ID marks on the tooth face.

 

Good to know, I will look at this when I get home. Are you referring to the thin machining lines on the teeth themselves?

 

Yes, these are the gear ID marks from Honda.

 

double check if the ring gear was bolted correctly from the pics the grooves seem to match.

 

Ok I've got a cluster **** of gears and would like to know some stuff. Do the machined lines on the all the gears have significance? Like does the 2 lines mean ls, 3 gsr, etc?

Also do the matching gears from main to counter need to have the same number of lines?

Do the cuffs between 3rd and 4th needs to look the same? I've noticed one of my 3rds looks the same all the way down and another I have is machined smooth from the bottom half down.

 

Yes the lines are significant on each gear. They do not always have the same lines on the opposing gear but they often do. You should always count the teeth and match the lines to your old part on a replacement gear or shaft. The combination of ID lines and tooth count will tell you what the gear fits.

The GSR and ITR C/S 3rd and 4th usually have the machined section but not always, it depends on the year that the part was manufactured.

 

So do the lines actually have a clue on what they are from, or just count the teeth? Is there a good resource or link for identifying the ratios for each based kn number of teeth?

 

Here is a link to another thread where we discussed a similar issue.

https://honda-tech.com/forums/transmission-drivetrain-127/ways-identify-if-your-trans-b16-gsr-2925369/

There are too many combinations for me to list them all but if you have questions on a specific gear, send me a picture with the tooth count and I will ID it for you.

 

got a chance to go out and count all my gears' teeth. i noticed on one of the links in the other thread there is a teeth count breakdown. on several of the gsr and ls gears they have the same count (ie: both 2nds are 20 teeth on main and 38 teeth on counter), does this mean they are identical or are there some slight difference between them? also, the mains for both have 13 teeth on 1st and 20 on second, again, identical?

 

I don't have the ratios in front of me but I would hazard a guess that even though the tooth count is the same, the diameter would be different to result in a different gear ratio (ls vs gsr 2nd). I think its around 1.9 for the LS and around 2.1 for the gsr one (ratios).

 

valid point. any body got a reference of diameter differences between the two?

 

1994-2001 GSR and LS both use the same main shaft and C/S 1st gear. The C/S 2nd is the same ratio but the GSR uses a dual cone 3 piece synchro vs the LS that uses a 1 piece single cone 2nd synchro. Since they both use the same M/S, you can install a GSR 2nd in an LS trans as long as you also change the synchro.

 

awesome, and thanks for everyones replies. good info in here

 

Ok the good counter 4th I have only has 29 teeth what in the hell is it from?

 

Any LS. Given the shaft diameter you're using - 1992-1993 cable LS, 1994-2001 hydro LS.

May I ask what you are doing now and the reason you're mixing things up for? LOL

 

Not trying to mix it up. Everything else is gsr stuff best i can tell.

 

Here is everything together now. Rotates fairly well but it seems like 2-5 dont sit as even from main to counter as they should. Am I just being paranoid?

 

It's hard to see exactly where each gear is in relation to all, but you do realize that the countershaft doesn't rest like that when the transmission case goes on, right?

 

Can you see the gears aren't lined up perfectly on ones you have put together before the case goes on? Also is it going to be ok to use a 29 tooth 4th on each shaft?

 

Maybe this will help in seeing what will be compatable and what's not (like the 4ths). Ive listed the gear with tooth count and machining lines; everything in here is useable besides the old counter...

New main: 1st 13. 2nd 20 with 2 lines. 3rd 25 1 line. 4th 29 2 lines. 5th 33 2 lines.*

New counter: 1st 42 1 line. 2nd 38 2 lines. 3rd 33 2 lines. 4th 29 2 lines. 5th 25. Counter has 2 lines.

Old counter: 1st 42 1 line. 2nd 38 2 lines. 3rd 34 1 line.

Old main: 1st 13. 2nd 20 2 lines. 3rd 25 1 line.*

Spares: 26, 2 lines. 33, 2 lines with a synchro.

 

You have a mis matched set with a GSR M/S and LS C/S.

GSR: New main: 1st 13. 2nd 20 with 2 lines. 3rd 25 1 line. 4th 29 2 lines. 5th 33 2 lines.*

LS: New counter: 1st 42 1 line. 2nd 38 2 lines. 3rd 33 2 lines. 4th 29 2 lines. 5th 25. Counter has 2 lines.

 

It is a gsr counter for sure. It's got 3 lines on the teeth. What would you recommend I set it up as with what I've got, or what do I need to get?
