I heard theres a way to tell by driving to the rev limit and comparing the results.

But I'm sure they stamp P72 for GSR on the YS1 transmission like they do the engine block right? Or some kind of identification.

I doubt Acura would really confuse themselves between their own trannys. There should be some kind of identification besides YS1.

Any help is gladly appreciated!

Forgot to mention, I have a CRX with a b16a, and I don't really wanna go from a jdm s1 tranny to an LS YS1. I need the GSR YS1!!!!!

If you're talking about the 92-93 GSR YS1, it would be stamped P61 more than likely, not P72. But It won't be stamped. If you're lucky, it'll have the YS1 sticker on it.

Why do you want to switch to the YS1 from the B16 trans? They're almost identical.

 

Well the GSR 92-93 has slightly better gear ratio's. On top of that my S1 4th is out and the 3rd may be going soon.

Even though it may be just a syncrho, wouldn't it be smarter to buy a USDM transmission with the same specs, and can go to the local Acura dealer here? Instead of searching endlessly

gear speed inc do sell the synchro's for the s1, but I heard parts aren't interchangeable. Such USDM and JDM. So what if its the shift forks? Etc etc. Plus I'm getting the S1 rebuilt at the same time.

 

Oh btw, if the YS1 sticker was still there, how would you identify from LS or GSR?

I also have a YS1 trans sitting on my garage floor with the sticker on it...GSR or LS?

I would like to know as well.

They are dead even in all except 5th where the YS1 is only 5mph shorter.

Hmm well that kinda sucks, I thought the higher gear ratio's the better? Also I thought the YS1 GSR tranny suppose to be equivalent to ITR transmissions

 

The YS1 is pretty much dead even with the 95-97 ITR and also the B16 transmissions.

The 94+ GSR trans and LS/GS/RS transmissions are both different though.

Hmm I'm keeping the S1 around most likely, so I can change between the two if one goes down.

But I still not able to figure out how to tell the difference between a GSR YS1 and LS YS1 trasmission.

I'm definately getting the GSR tranny from my friend, but it would suck if I couldn't tell between the two.

But if its short geared than it would be just like my S1.

Thanks for the info then.

Instead of debating you on which trans is better.....

Here's a link to your answer.

Just to clarify, no YS1 ever came with any type of P72 anything. The YS1 is a cable tranny found on usdm B18A, and gsr B17 powered integra's.
The JDM YS1 had only the option of lsd, meaning only about 1 out of 15 had it, and this was mated to a B16A.

The P72 is a newer gen engine that "only" came with the newer hydro gearbox. And P72 blocks are 1.8L not 1.7L like the 1st gsr which was basically a usdm only stroked B16A.

 

There is no stamp or sticker to determine the difference between the GS-R an LS. Also if you have a Y1, S1, J1 ect from an 89-90 then you have to change the clutch disc to run the YS-1 because the spline shaft is larger.

 

Not a problem at all, the clutch disc was already covered.

P72 is GSR, didn't dig down into it, as I never owned a GSR, I think I got P72 from an ecu I was looking at on ebay as well as a P72 block at a friends shop.

If P72 does not come with YS1, well that is something new. Though its not like I actually new which code it was suppose to be, therefore I said P72 since that was a GSR code.

If the dealer do not identify between transmissions, they must have had a reason obviously. But I'm sure theres some identification that no ones here obviously.

The gear counts and etc were already covered. And all I was asking was a quicker way to identify, such as just a code.

But thats ok, I'll figure it out little by little. Pretty much all my knowledge about hondas is from my crx and b16a.

I just want to know more than just that, but I guess in time I will.

 

1992-93 Integra GSR = P61 -its a B17A
1994-01 Integra GSR = P72 -its a B18C1

 

Thanks man, will keep note

The dealer did have a reason, all they had to do is look at what motor was in the car to see what tranny it was. Only once you take it out of the car do you have a problem with identification. Whats so hard about popping the case? you dont even have to disassemble the shafts to count the final gear. stop ***** footing around and pop the case, all you need is a new tube of honda bond to seal it back up

 

What you may be thinking its ***** footing, when the transmission is not even here . I bought from a friends shop and will be installing it tomorrow over there since they got the air tools and etc to get it all done faster.

And to make it clear, I don't have to use air tools just to pop open a transaxle thats outside of the car.

It would be pretty rude to question my friend, as hes been good to me.

I'm more respectful than that. Thefore I try to find outside sources to identify it. Without question.

 

Unless you are looking for damage, why would you open the case?

Get out a magic marker and start spinning the input shaft and counting till the output shaft goes around one time.

math is your friend

In order to if it's short-geared or not you would either have to open it up and count gear teeth or install and check your engine RPM's in gear while driving.

this is the easiest way without cracking the case..
