I got a question! I did some research and couldn't exactly find any info. Is it possible to replace the cable YS1 3/4th syncro sleeve with a hydro ls tranny? If it is possible would you recommend it? My 4th gear does not want to stay in, I couldn't downshift in it but as soon as I step on it, it kicks it out of gear! Could it be just the syncro sleeve? Any info would be good, thanks guys!

 

Curious as to why you want to use a syncro sleeve thats not the one made for your trans? Is there supposed to be benefits to a hydro ls syncro? Also, if you're not grinding while shifting into 4th I would look elsewhere before cracking open your trans case. I suppose it "could" be the syncro but I wouldnt bet on it. Unless somehow it's binding/ keeping your from fully engaging your dog teeth on your speed gear and slipping back off. I'd check all your linkage over really well and check for binding. If something is tweaked/ twisted/ bent/ binding it could be putting stress on the shifter pulling it out of gear while you're in 4th.

 

Yes, kind of. I agree that you should split the case first. Good chance all you will need is a synchro spring unless it has been doing it for a good while. Then, you'll probably want the sleeve kit and a 4th gear. Why I say kind of is some of the YS1's have a slightly different size shift fork. If this is the case for you, just use the shift fork that came from the trans you rob the sleeve kit from. Also, you could just swap all of the internals from the hydro trans into your YS1 case...

 

I'm not prefering to go with an LS sleeve or say I'm going to benefit from it, it's just that a friend recently got a gsr trans and took his LS one out, he's going to let me have whatever it is I need to fix mine. So it's possibly not the sleeve then? I put it in 4th and it downshifts but when I step on it, it grinds and kicks it out of gear!

 

from what i gather:
92-93 b-series cable transmission can use 94-01 internals
90-91 b-series cable transmission can use 90-91 internals as well as 88-91 JDM B16 internals

i did some research to rebuild my blown 90 LS cable trans, and i came across this info on a dozen sites as well as transmission rebuild kits stating the same facts. i hope this info is useful to you.

 

Like I said first, give your linkage a really good inspection. Check out the bushings, mounting hardware, and bearings. It's possible that something is binding and putting a slight pull on the shifter causing it to pop out of gear. I'm not saying this IS your problem but I would definately look all of this over before I pulled my trans out and opened the case up. Can you physically hold the car in gear and have it stay in? Have you ever done something like this? It will require several tools that normal people don't have in their home garages.

 

Thanks That really helps out!

Ok I'll try that tomorrow! I'm hoping it's just the shift linkage but I doubt it. Na I can't hold it in gear it'll just grind if I hold it. I don't have too many tools but I used to work at Honda and a technician told me he'd charge me 50 bucks to open it and replace the syncro sleeves but if I take out the tranny.

 

Well G/L with getting it taken care of. Thats a pretty dang nice guys swapping those out for you for only $50. If I was you I would honestly just buy a brand new set of syncros. They're really not that expensive and you'll KNOW that you won't have to crack that back open in the near future. No sense in not doing them all while you're in there. It really just boils down to half assed maint. for ignoring what should be done while you're inside the case.

 

true true, well the syncro set pretty much comes with everything right? sorry noob question. Like the sleeves, springs and all that right? You think I would need a new gear?

 

It would all depend on how complete of a kit you got. If you're not literally scraping up pennies to fix this, I would recommend getting a "overhaul kit" which basically consists of new bearings also. Theres no way to tell if you'll need a new gear until you're in there. I would honestly highly doubt it. Most likely your dog teeth should be fine but your blocking rings should be the part needing replaced. They're made usually of softer material so that they go before your speed gear does.

 

Unfortunately, an overhaul kit does not typically come with what you REALLY need on a Honda trans.

It does come with bearings, seals and sychro brass. It DOES NOT come with synchro springs (the part that is worn when you first get a high RPM grind), sleeves (the part that the shift fork attaches to and the dog teeth wear off of), hubs (many times this gets worn so engagement is not as smooth as it should be), or any needle bearings.

More than likely, if you do have internal issues, these are the parts that would actually need replaced:

1. Synchro spring(s)
2. Sleeve(s)
3. Synchro brass
4. Very slight chance of a bent shift fork. Decent chance that the shift fork is worn beyond service limit if you have been holding the shifter to keep it in gear.
