I have searched and found this information 94-95 trannies use a sticker id, not the riveted vin. y80=gsr/jdm something. s80= numerous things.
THE QUESTION: I got the tranny today. It says y80 on the id sticker. Is there any other way of telling if its a true gsr besides that id sticker? I am not worried about being ripped off because I got it for a price cheaper than most ls trannies. I just wanted to know because there might be a possiblity that a y80 sticker could has been swapped out and glued on in favor of something else.

 

there was a thread within the last week that was all about that...count the number of teeth on the counter shaft and the opposing gear on the input shaft and divide one by the other, do that for each gear including final drive and refference it to each transmissions specs and that will tell you for sure.

 

tru....i dont think i want to know that bad

Yeah, I'll try to find that post, I participated in it. However, I would like to point out that counting the number of teeth on the countershaft WILL not determine if it is a GSR/LS/something else.

I did a countershaft/final drive swap in my LS a while ago and found out that the 4.266 and 4.400 countershaft (from LS and GSR respectively) have the SAME number of teeth. Same with the final drive. Same number of teeth. The difference is that they are shaped slightly differently. And the teeth on the countershafts start at a slightly different point on the LS and GSR.

It's pretty hard to tell. Maybe you can count the number of teeth on the other gears maybe. But unless you have both countershafts next to each other to compare the very slight shape difference, it's gonna be nearly impossible to tell.

It's probably easiest to put the tranny in and drive it and see, rather than pulling it apart. It was a nightmare pulling my tranny apart. I plan to never do that again.

EDIT: Here's the thread about it. Read my posts and my crappy "text drawings" and maybe you'll understand. Hehe. https://honda-tech.com/zerothread?id=845119

 

Thanks. Yeah I will probably just right down test data from a transmission/speed/rpm calculator for the bseries (if there is one; i know there is one for dseries) and see where it closely matches.

Transmission Specs]

You'll find all the gear ratios and what not from all B Series transmissions there. However, you'll also notice, that the S80 and Y80 transmissions are not vehicle specific. When you drive it, it should be pretty obvious in 4th and 5th gear, at low speeds, what tranny it is. An LS trannsmission will be around 2k rpm in 5th gear at 45mph. The GSR would be higher in the RPMs.

Good luck finding it out. Hopefully it will be a pleasant surprise.
