I haven't been on here in a while because my car has been getting neglected. But I just got a new tranny because as some of you know my y1 w/ open diff broke(twice). The new one is a ys1 w/ lsd <40,000 miles. The guy bought a full swap from hmotorsonline.com and then changed his mind on the tranny(don't know what he went with).

The question I have is, if I have motor work done(bore, rods, pistons, cam) and run 16lbs of boost shooting for 375hp, will the tranny handle that. I am new to performance mods and don't want to ruin the tranny. I was only running 5lbs on the stock trans open diff(it broke) and stock internals. This is supposed to be the stock option lsd so can it handle the increase in power?

Some pics

 

I think your more likely to find money laying on the street than one of these transmissions laying around. Good find is the trans any good?

 

The guy I got it from(I just drove 500 miles round trip through Chicago rush hour traffic twice) said that it was taken off the engine when it came in for his full swap and he didn't use it. He signed a contract for 25% re-embursment of purchase price if anything was found to be wrong upon install so I am pretty confident it is in good shape.

I stumbled on it and now with more research I'm finding out that I probably got a steal(as long as everything works) because it sounds like these are rare.

 

pretty sure those transmissions didnt have lsd. if it did it would have the word LSD engraved in the side of it

 

Its an lsd.

i was actually just looking up some b16 tranny's on a local site. What is a better option, to buy the LSD tranny and risk it breaking or should i do an LSD install kit. Has anyone heard of that before?

 

No, the old school YS1 tranny's with the rare option of LSD from Japan did not have the stamping

It was a rare option, even in Japan, only 1 out of 15 models had the option, and the tranny was only in production for two years in one Inegtra model

As far as mileage goes, LOL...you and the person you bought it from have no clue as to what the actual mileage is, people just make numbers up. Unless it came out of a complete assembled front end clip, there is no way to know

If the internals are not shot, you should be able to use it with your setup. The most common problem known for this tranny is the 3rd gear syncro....it would be the 1st to show sign's of wear, hopefully yours is good

 

Thanks for that link. I'll check for the stamp but it is clear that it's lsd. Wonder why they didn't stamp all of them.

Once I open it up, 3rd gear wear would be a key point of interest then?

 

how can u tell its LSD without the engraving?

 

A 10 second search and you would have learned ......it's pretty easy

 

you bet!

 

Thanks for the help Deetz. I may come to you with other questions if that is ok with you. Still a noob to the world of Honda.

 

^^ ha ha, sure thing, ask away anytime!!!

oh, btw....it's a wicked good transmission, best of the cable tranny's

 

In the last pic I posted there is something on the tranny above the diff with hose connections that I don't remember being on my y1. What is it or am I crazy and just don't remember from the tear down of the old trans about a year ago.

 

its a cable vss the hoses go to the power steering to give the vss oil. you hook up your cable driven speedometer to the vss

 

Dumb question....without power steering, what do I hook it up to???

 

^^ just loop it with a hose

 

Yeah that p/s hose thing is weird. The d-series transmissions didn't have that. I just used a vss gear off a d-series trans and it doesn't even have the p/s lines for lube. Apparently they drop right into b-series transmissions just fyi

 

It's not that it's weird......cars like integra's and SiR civic's and crx's had speed sensitive power steering, that what that hookup is for on the better models

 

how do you get the vss out of a d series transmission (D15b2)? it seems like it cant be taken out.

 

when you do that make sure you put power steering fluid in it first

 

okay guys i was wondering if a lsd out a b16 cable would work on a ls cable. . . new to the honda scene.

 

u mean would the transmission be swappable? of course all b series except for early gen preludes are swappable with heads, transmissions etc

 

I was able to get some time today to crack open the trans and take a look inside. Everything appeared to be in good condition. You guys have told me the first thing to go in these trannies is the 3rd gear syncros and they look good so that makes me happy. I did find something that would have been a big issue had I not checked inside before installing the trans. There was a bolt stuck to the magnetic strip at the bottom of the trans casing. It went to the mount for the reverse shift fork linkage. There are two bolts that hold down that bracket. The one was completely out and the other had 4 turns by hand before it got tight. I'm pretty sure that had I tried to go into reverse, the bracket would have bound and not let it shift. And if the other bolt had come out at speed, that would have been a whole other problem. Luckily I checked and replaced and tightened the bolts so there shouldn't be any problems.
