I desided to check the tranny code on my RS with a b18b. It says Y80 on it along with these numbers: 1026450.

After reviewing the chart on http://tiiite.b16a.com/Bgears.htm it shows that LS/GS/RS tegs only had S80 trannies. And that the GSR and JDM SiR/SiG had the Y80 tranny. Does this mean I have a GSR tranny? This would explain why my car is so much faster than my friends LS w/ similar mods.

What do your guys LS/GS/RS tegs say on the tranny?

 

Where can we locate that tag that has the tranny code on it?
Do you need to lift the car up?

 

No, open the hood and look at the tranny. You will see a sticker with a bar code on it right to the left of the engine code stamp(where it says b18b, b18c1, ect.). It says the tranny code right there on that sticker with the bar code on it.

 

I was just on the highway and this is what I found.

in 5th gear w/17s and 205/40/17 tires at 3000 RPM I am at 67 MPH
In 5th at 3500 RPM Im at 78 MPH
In 4th at 4000 RPM Im at 68 MRH

Does this sound right for a GSR tranny?

 

did u buy the car from some "rice boy"?
if you want i'll look at mine I have a 95RS and my buddy has a 94RS
and i'll tell u what my code is

 

No, I bought it from a dealership who bought it from an auction in NY. Yeah, if you would look at your code for me, that would be great. What does buying it from a "Rice boy" have anything to do with the tranny? I could see maybe if I were asking about altezzas.

I'll be really happy if my car turns out to have a GSR tranny. I was planning on buying one anyways when I build my block, and get a Vtec head.

 

Nah, that sounds more like the RS/LS tranny. In 5th gear going 80mph is about 3500rpm for me too. I drive an RS.

I will check for the tag as well, I'm still not sure where exactly to look though.

 

5th gear @ 80 MPH w/ a GSR tranny would put you at around 4000 RPMS.

 

You have an LS tranny

 

I'll go to 4000 in 5th and see where Im at. I do have massive wheels and tires, so that will make the ratio considerably longer.

 

205/40/17 hardly changes your ratio at all...you have an LS tranny. I used to have the same size tires until I got sick of my 17's and ditched them.

 

Nope...that's about right for an RS tranny.

 

Sounds like an LS to me!

 

At 4000 RPM in 5th, Im at 84 mph.

If my tranny is an LS tranny, why does it say Y80 on it? That makes no sence at all!!!!!

 

ok i just ran outside to check out my numbers.....
my LS trans says Y80
and my GSR trans say S80
so yer straight

 

Thats really weird. My friends LS says S80, and all of the charts I looked at yesterday said the LS/GS/RS only had the S80. I don't know.

Can some more of you check your trannies? GSR owners and LS owners???!!!

 

who cares? your gearing is clearly LS gearing. the difference in diameter of your wheels is negligable.

 

I kinda care, I don't want to waist $600 on a tranny that I already have.

 

Haven't you confirmed your gear ratios are LS gear ratios judging by your speed & rpm?

 

Truse me, its an LS trans. At 4000 rpms in my car, i am going 80mph. I have a GSR trans. Your at 3500rpms. Its an LS trans. The code on the trans means absolutely nothing. You cannot tell a trans based on the code on the newer hydraulic transmissions. Only on the old cable trans could you tell. The only exception to this rule is if on the casing it is stamped YS1 LSD. Then you have an ITR trans.
