I have a Y1 CRX jdm LSD tranny for my b16a. I read in this link http://www.honda-r.org.uk/pdfs/August2000.PDF they said that in the ealier EF 8/9 B16a CRX Viscious type LSD were optional. If that's the case I need to run some special gear oil right? What are the chances it's helical as I've read before, I hope it's helical like the rest so I can use Honda MTF. Unfortunately I didn't get to take a look inside the tranny when we put it on. Anybody have and thoughts? Thanks.

 

I also have the Y1 LSD tranny. I used Honda MTF and my LSD chatters extremely bad. I've pretty much learned to live with it, but if there's special fluid I should be using I didn't know.

I'm not real knowledgeable on the different types of LSD's, so I'm all ears.

 

i use honda mtf for my ITR gearbox

im not sure if in early ef8/9 they came with viscous type LSD , i tot only clutch type LSD

is ur LSD when u spin one wheel , the other wheel spin as well to the same direction ??

 

i have a JDM Y1 with LSD in my hatch and it also chatters horribly. I use Honda MTF. If there is something else that I can use to quiet it down, i would love to try it.

At first I thought my CV joints were bad, but after replacing both axles i still have the noise. Its a chattering when making slow turns and I can feel it throughout the car. It is also extremely difficult to turn the wheel when moving slow.

 

kinda crazy how so many people have this problem.. i thought I was the only "lucky" one.. lol

Someone has gotta have an answer as to what kinda fluid goes in there?? Everyone shop I talk to says, "We use Honda MTF..blah blah".. no one knows about the LSD cable trannies though..

I work at a shop, and some pick-up trucks actually use a special "friction modifier" additive in their differentials equipped with LSD. Not all but some. If you don't use it when it's called for, it chatters like mine. I've considered putting some in to try it, but I'm scared to make it worse..

 

LSD INFO
i don't think it has a viscous LSD because that would cost a lot more....

True, but most importers don't check what type of lsd cuz you gotta take the gotta take the diff out to see right? Hope it's helical like all the other lsd in newer jdm cars so I can use honda mtf and feel safe. Has anyone seen a honda viscious lsd in their b16a? My lsd doesn't chatter, it's pretty good so far.

 

Hey CRXB16aJDM....
which tranny? which mounts? which intermediate shaft? which axles? which hubs?

maybe yours is quiet becuase you have a different setup than i.

I have Y1 LSD, HCP mounts, 90-93 integra intermediate shaft and axles and crx si hubs and mad LSD chatter.

 

Y1, orginal motor mounts with inserts for front and rear, re-welded tranny mount, 90-93 axles, and a midnight performance subframe, similar to traction bars out there. Hubs from my orginal dx auto. Does it chatter when your launching? It's not a ticking noise like axles right?

 

maybe the bend on your axles is too much and your stressing the knuckes in the axles?? i dunno just a guess.

guys just use thicker oil, goto pep boys and buy this:

GL-5 80w/90
or
75w-90 or 75w-80 GL5 gear oil for FWD trannies

if its still too much chatter, add some ford friction additives. Similar cases for clutch type LSDs ... here:
Ford friction modifier for FWD.

I've considered your idea, but 80w-90 is a hella lot thicker than 10w-30, which is pretty much the equivalent to Honda MTF. As far as your idea of using a friction modifier additive, I've considered this, but does anyone know if it would mix with Honda MTF?

Like I posted earlier in this thread, a lot of pick-ups and RWD vehicles with clutch type LSD use friction modifier additives to reduce chatter. I'm just scared to do it and hurt something.

Does anyone know if there could be a side efect of using this additive if it isn't called for. I'm considering putting in some more Honda MTF, and adding the friction modifier additive.

I've done it about 50 maybe 60 times for customers and my own cars ... as for friction modifier, it will reduce lsd life form 20yrs to 18yrs before replacing plates... unless of course you do tourcar championship races, in which case it would be every 3 seasons you'd replace the discs.

you'll be fine, dont be scared.

Also, it helps if you have a very thick front sway bar with poly bushings, and poly bushings on your rack ... this tightens up the front end and reduces chatter to an extent..

do you think an LSD additive would mix with Honda MTF, or should I use 80w-90 for sure? I'm kinda skeptical of putting that thick of a gear lube in my Honda tranny. Not just the thickness, but the detergents in the GL5 fluid. Would it protect as good as MTF? I know that the MTF is equivalent to 10w-30 motor oil.

I hate to be overly cautious, but this is my daily driver. If I can help it, I'd rather not learn the hard way.

 

youre right to an extebt but the thicker oil mix is what helps w/ clutchs from a practical point of view. The detergent factor will not affect the clutch life. when she gets a bit nothcy in about 10k miles or o, change it again

Just wanted to give this thread a little bump..


I have updated news. I talked to HASport about the tranny and the problems everyone is having. He said to use Honda MTF and put in an LSD additive. He recommended the GM additive, but he said they will all work.

I'll be replacing my clutch and flywheel soon, so I'll do the fluid change then. I'll let you guys know how it comes out..

 

I just bought an LSD Y1 tranny. The shop that sold it to me opened it before selling it. I can tell there is an LSD in there, but I'm not quite sure how to see what type it is. As I can understand from reading this thread, it must be either a helical or viscous LSD. How can I know?

 

Someone? Anyone?

 

Come on guys!
