possible tranny swap?

I am kinda wanting performance, but right now my teg is a daily driver so a drop in fuel economy is not a good idea. Not to mention that I havent been able to even get in touch with the guy who “was” gonna sell me the tranny. So now, I don’t even have the opportunity to buy one anyway. But its all good. I think at this point that I would rather just fix what I have. I think I will wait until I do some engine work before I try to invest in a tranny swap anyway. But thanx for your input guys.

If you haven’t done a lot of research on the topic… beware of guys trying to sell you a “GS-R” trans. Do a search on the topic, but in a nut shell: There is no way to tell the 2 different YS1 trans apart from looking at it. Honda’s joke on the G2 owners. “Let’s put the same code on two different geared trans in all 92-93 G2’s” My point is, A LOT of guys will try to rip you off by selling you a YS1 and calling it a GS-R trans when it is just the same long geared trans you already have.

really? The guy did assure me it was a GS-R tranny but then again, whos to say he wasn’t lying right? I will keep this in mind if a tranny swap ever ends up on the list of things to do again. Thanks man.

Wraith so is there like anyway to tell the difference? cause i always thought they those idiots at Honda named both trannies with the same code.

To date, there has not been an effective visual inspection that is 100% accurate. Watching it come out of what looks like an original 92-93 GS-R is not even fool proof. Who’s to say they didn’t swap it for what ever reason. There are only 2 effective ways to tell if you are dealing with a true YS1 “short gear” trans. Of course they both involve a bit of labor.

The “easy way” - open the case and count the teeth on ALL of the gear sets and compare them to the numbers found on the site I posted or others. Keeping in mind that it is somewhat popular to swap a YS1 “long gear” 5th in to a YS1 “short gear” trans. There is also the possibility that a 94+ “hydro trans” internals were swapped in.

The “hard way” - put the trans in the car and compare the RPM & MPH results in various gears to results posted on the boards. This could be an “easy way” if it is still in the seller’s car that he can give you a test ride/drive, and you help remove it.

There must be a reason Honda did this in the first place, either mistake or just trying to be sneaky, who knows? Until someone at Honda tells us we will probably never know. Would it have been so hard to put a “YS2” on the case?
