Ok, so I bought a tranny from a guy a few months back and he stated it was a GSR. So I took his word for it since it was only 200 bucks. I brought it home and a month or so later, ya I know, I decided to open it up. Well I counted the ring gear and it matched that of an LS tranny. I immediately got pissed and closed it up and chalked it up as a loss. When I eventually did my B swap I put this tranny in and turns out 5th gear doesnt work.

So I set out on a mission to find a GSR trans and found one on Craigslist for 500. Picked it up and installed it last night but it turns out it was a hell of a lot slower then the tranny I originally bought. I did some 4k rpm recording of speed and it looks like i got screwed on this 500 dollar tranny I just bought and it is an LS tranny.

So I take the old tranny apart again and do a count on all of the teeth on every gear to see why exactly this one is faster. This is what it came up with:

1st gear: 3.23
Counter= 42 (all B series)
Main= 13 (all B series)

2nd gear: 2.0
Counter= 38 (GSR or LS)
Main= 19 (ITR or Civic Si)

3rd gear: 1.375
Counter= 33 (LS)
Main= 24 (ITR or Civic Si)

4th gear: 1.036
Counter= 29 (unknown.... to me at least)
Main= 28 (ITR or Civic Si)

5th gear:.788
Counter= 26 (ITR or GSR)
Main= 33 (ITR or GSR)

Final Drive:
Counter= 15 (all except ITR)
Ring Gear= 64 (LS)

Someone please tell me what this set up is and if its any good or not.

Thanks.


*****************EDIT**************

So it turns out this set up is faster than a GSR if I only had the 4.4 final drive. With the 4.266 final drive its a hair slower than the GSR but still a hell of a lot faster than the LS trans. So now I have a 200 dollar Frankenstein tranny and 500 dollar LS tranny. Great lol...

 

Just found the 5th gear problem with this tranny. Badly worn 5/R Synchro sleeve. This should be fun.

 

No responses? Surely this cant be stumping you guys.... can it?

 

You have mis matched gears. I am surprised that it ran at all!

Post some pics and we will sort it out.

 

 

It is important to look at the ID lines on Honda/Acura gears and not only the tooth count. You have a mis matched gear set:

countershaft 1/2/3/4/5 = 1992-1993 YS1 Integra LS

mainshaft 1/2/3/4/5 = B16

FD= LS

 

So how do I fix? I mean the car drove just fine minus the 5th gear issue. I should have provided pictures of that as well.

The teeth on the 5th gear side of the synchro sleeve are all rounded and almost completely gone. The dog teeth on the 5th gear are also rounded which is why I think the gear is not engaging. Synchro spring is looking tired but for some reason the synchro teeth look fine.

Do I need to get a whole new 5th gear set up?

Also, 5th gear on the mainshaft doesnt match the B16 5th gear.... at least not with the information that I found.

 

The M/S 5th is B16 hydro 99-00 Civic Si 33T 3 lines (1 thin bottom, 1 thick center, 1 thin top) OEM Honda # 23581-P21-F00

I would NOT run mis matched gears. It may work for the short term but the gears will soon wear and break from misalignment.

 

Thanks for that.... so what do you suggest I do to fix this?

 

Change the C/S 2/3/4/5 gears to B16 (1st is the same for both), replace the M/S 5th gear, replace the 5th sleeve, spring and synchro.... or scrap the trans for spare parts and start over as this may be too expensive to repair.

 

Well that sucks.....

Thanks for your help

 

Ok so I picked up a B16 tranny for trade for some of my spare parts I had laying around. Seller said it needed a new shift fork and when I got there the input shaft would not rotate at all.

Seemed like something was wrong but it was worth it for me since all I need is the countershaft set up and 5th gear.

Took it home opened her up and there was a crap load of crap in there lol very dirty tranny but all in all the gears looked great and the synchros, sleeves and dog teeth were all in great condition.

Sooooooo...... heres my question

Can I take the countershaft set up and 5th gear from the b16 I just got and put that in the GSR/LS Tranny housing that I originally bought? What will need to be swapped in order to be ok.

 

Well, I swapped over the B16 5th gear, synchro, and synchro sleeve onto the main shaft. Then swapped the whole countershaft setup from the B16 tranny I just picked up.Used the shims for the mainshaft that came with the tranny and same mainshaft. Kept the same shims for the diff and the same diff. Only new parts to the tranny are the 5th gear setup for the mainshaft and the whole countershaft.

The trans runs great, but there is a loud whining noise coming from the tranny now and its speed dependent not RPM. The faster I go the louder and high pitched it gets. Doesnt matter if Im in neutral or if the clutch is pushed in..... what could this be?

 

You had an LS countershaft and ring gear and then installed a B16 countershaft. Even though the B16 and LS both have a 15 tooth countershaft, they are different. The teeth align differently to accomodate the 66 tooth ring gear on the B16 and 64 tooth ring gear on the LS. The B16 C/S has 3 ID marks on the gear and the LS has 2 ID marks. Either run the match set LS FD or match set B16 and the problem will be fixed.

 

So is it ok to run like this until I get the correct final drive. I hate to sound like a dumb *** but when it cones to trannys that's exactly what I am lol. I really do appreciate all the info you're giving me as well.

 

It's not really 'ok' to run it like that.

You'll eventually break something.


Match the ring gear and countershaft and you'll fix the whine.

 

Do not run it like this.

 

Ok, Ill take it out and try again lol.

One final question... hopefully. Can it be any 4.4, B16 or GSR, diff that I install or does it have to be specific to the B16. Do I need to replace the diff or can I just replace the ring gear on this 4.266 diff?

 

The GSR has a larger diameter hole in the ring gear. Reuse the B16/LS diff and change the ring gear to a B16 66 tooth.

 

Got it.... wil do. Thanks again for all the info.

Hopefully I havent screwed anything up. I ended up driving it to work this morning not knowing it was bad. Luckily Im only 5 minutes from my job.
