Cable B series Discussion
Ok this is for people with Y1, S1, J1, YS1 cable B series trannies. I have searched but havent found what i am looking for. Theres a lot of talk about not being able to swap certain diffs, synchros, etc I am im interested in peoples expierience an knowledge.
I have an S1 tranny an wanted LSD so I found a Y1 tranny an took an LSD out of it an swapped it into my tranny. Some people said you cant do it, some people said yes you can, well its in my car an its running so I assume im ok for now. A friend of mine with a Y1 blew his stock diff out an i gave him my S1 open diff, and his is still running to this day. I want to know if anyone has done this also, tried different diffs etc.
Are synchros swappable? I have heard yes an no. I am NOT a transmission guy AT ALL so any info on the difference between trannys, thoeys etc are welcome. thanks
what i know is this, The YS1 is the shortest geared, ITR LSD fits into it, an you can supposedly use hydro synchros from other B series trannyies for it.
S1 same gearing as a 96 type-R, rarely has LSD
J1 second shortest geared trans
Y1 longest geared B16 tranny most often of the trans that come with LSD

Re: Cable B series Discussion (blackmagicCRX)
I could tell ya but I would have to kill yah.....j/k It would take pages to do comparisons on what transmissions cross over and then it gets to the point of USDM vs JDM. Which do you have? Then the person says...JDM I think....no wait I think the guy ripped me off and sold me a USDM tranny!! or I don't know what it is...I took the tag off because it was falling off and don't remember. Y-1 and S-1 will cross over as far as synchros but, they will have different gear ratios. A-1 and J-1 will do the same. JDM YS-1 are the great trannies as you are able to change final drives to the Hydro versions and have short gearing as well. This is also available in the USDM GSR tranny that is comparable to the JDM Version. If you got ripped and ended up with an Integra LS YS-1 don't fret you can add a turbo and a 4.78 final and you'll be just fine!!

Re: Cable B series Discussion (Jurassic Four)
What I know of the YS-1 :
Most are LS units - some people claim that they are all from GSRs, but this is not the case. All 92-93 Integra 5spd gearboxes are YS-1. There is no external clue as to what gearset it contains that I know of.
The internals are identical to the 94+ hydro clutch units. This means swapping GSR/ITR gears in is relatively easy.
In order to do this, you will need to clearance the case to fit the larger diameter diff carrier (very minor - I have photos of the areas I trimmed if anyone is interested).
The shift forks will also need to be changed over to the GSR/ITR versions. It seems that the YS1 1-2 and 5-R forks will work (in fact, the 5-R part # is the same for all 5spd boxes 92+; the 1-2 fork is a different PN, but looks very similar in terms of inner diameter). The 3-4 fork is much wider for GSR and ITR, and you will need it. At any rate, the newer style welded forks seem much stronger, and I'd use all three.
The late model GSR/ITR diff carrier bearings fit in the case without any problems (and no preload setting hassles; just one shim is used, same as the stock YS1 bearings).
You will need a 92+ clutch disc, as the main shaft is the same (larger) diameter as the hydro transmissions, not the smaller 91 and older disc. Throwout bearing and spring is the same 90-93.
Hope this is useful to someone.

that is some GREAT info. So its possible to pick up a YS1 LS tranny an make a ITR trans out of it basically? I mean i dont htink it would be cost effective, but its interesting. ANy one have this kind of info on the JDM trannies?

Yes, you would have an ITR transmission with a cable clutch. Actually, once the cost and hassle of a cable-hydro conversion is factored in (either converting over to hydraulic clutch entirely or using an adapter), lots of cable-clutch chassis people have decided they would rather keep the cable setup and just change the internals.
With the availability of ITR LSDs and GSR gearsets, I chose to build a hybrid GSR gearbox with LSD for my 91 Integra, keeping the cable clutch.
Also, I *believe* that the JDM YS1 is the same as the USDM model, except that it could be ordered w/ an LSD as an option.

Re: Cable B series Discussion (acy76)
Very well put!! I have the 4.78 Type R final with JDM Xsi shaft gears (like USDM GSR) First gear is shorter on USDM GSR but that changes when you put the 4.78 final drive kit because you change first gear. We have the synchros available with carbon coating for 3rd 4th and 5th gears.
