How to fix synchros
 

I just bought a 91 si crx and the sinkroids (not sure how to spell it) But are they fixable or do i need a new clutch and all?



thanks

I have no idea what the ---- your talking about but that part is probably next to your headlamp oil

Re:How to fix sinkroids??<<spelling
 

he's talking about the synchros in the tranny. Yes synchros can be fixed if you got alot of $$$

Re:How to fix sinkroids??<<spelling
 

How much? range? or just buy new tranny. B/c id rather change mine instead b/c I have a hydro ls tranny and its hard to find. I want it over gsr trannys and stuff b.c i dont want to be on da freeway going 70mph and and reving over 3 grand with da gsr tran. ls tranny revs lower, saves gas!

Re:How to fix sinkroids??<<spelling
 

99% of the time the syncro's dont go bad, the slider on honda tranny's always go bad, they get a sharp edge and pass the syncro to fast and grind on the gear, been through 3 gsr tranny's because of this (1 being mine and 2 my friend)

Re:How to fix sinkroids??<<spelling
 

If you need some roids hit hotrex up, he can get cypinate but I like eq its deca for horses, makes you big FAST! and comes in 30mil jugs :P

Re:How to fix sinkroids??<<spelling
 

bicep goes big

pipi go...bye bye

Re:How to fix sinkroids??<<spelling
 

i don't know about roids, but when i took androstat, i use to lay down pipe like there's no tommorow!

Re:How to fix sinkroids??<<spelling
 

sorry for the hijack but i have a qustion as well.

I have a 99' si and evey now and then it grinds into 2nd. Its only when im on it really hard but just shifting into second normally feels a little well, "sandy" for lack of a better term, but its only when its up to temp, when i just crank it, it doesnt do it

Re:How to fix synchros
 

i have heard that gm syncro mesh tranny fluid might solve the problem of a slight grind. try it out!!

Re:How to fix sinkroids??<<spelling
 

you'd be better off getting a new/used tranny, hydro ls aren't that hard to come by, it's the cable ls tranny's that are hard to come by.


try changing your tranny fluid. use either honda mtf, or gm synchro mesh.

Re:How to fix synchros
 

ya, i am looking to get my tranny fixed in my teg. Everytime i get to redline and shift it grinds. Is it that hard to rebuild it yourself? Or should i just be looking for a whole new tranny?

Re:How to fix synchros
 

I AGREE! get the honda tranny fluid...I've known more than a few people that have had shifting issues, and when they change the oil to the honda stuff all of there problems were gone..

Re:How to fix synchros
 

There is a cheap fix that works damn good. I tried it and WOW my pos ebay tranny that had ------- water in it now shifts like brand spankin new at any rpm. I got this tip from a veteran of the drag racing world. It involves a ton of work but cost next to nothing (your time thats about it) Here goes...

Completely dissasemble your tranny. Purchase new syncro rings and just the rings. You do not need syncros or hubs. Get yourself a small triangle shaped file and have a seat. Start to gently file the rounded edge "tips" of the syncros and hubs. Sure theres a shitload of work going over every tooth but basicaly you reshape them just a tad. Nothing too extreme just to bring back a somewhat point to the grooves. Re-assemble and fill her up with GM syncromesh. Do NOT get the friction modified ----. Trust me on this it works!!

Re:How to fix synchros
 

^^^ wow, i wanna try that synchro fixing thingy. but the only problem is i never took the gear box off before and i dont know how the synchros look like, any pix guys? i have a y8 tranny that grinds in 2nd really bad, cant get it into gear so its 1st to 3rd!

Re:How to fix synchros
 

just try changing your mtf first ;)

Re:How to fix synchros
 

well the tranny is already out and chillin' in my backyard so i mine as well crack it open.

Re:How to fix synchros
 

could anyone tell me more about this, because i am going to do it?

Re: How to fix synchros
 

kill yourself?

D sync's only go bad after everything else is trashed.

Re: How to fix synchros
 

the gm syncro mesh works great but you have to get friction modified

Re: How to fix synchros
 

im running the ls tranny...


im using the syncromesh and it still scrapes in 3rd.

Re: How to fix synchros
 

start saving your lunch money

Re: How to fix synchros
 

GM Synchromesh Friction modified is the one you want. ---- works miracles. Granted it's no fix but it's one mother fucker of a bandaid.

Re: How to fix synchros
 

checkin the date and I thought pork and polish was back again.

Re: How to fix synchros
 

I worked at a few gm dealers and syncromesh works great but so does ATF. MM6- the six speed trans in the trans am, camero, and corvett all use Dexron ATF. With the tight clearances in honda trans, maybe some ATF would aid, it would for sure clean up any crap stuck in the syncros and bearings, rings, whatever. Maybe run some ATF for a week then drain it and ad syncromesh. I have a 2000 si and my tranny has those shifting issues, when the bastard was under warranty the mf'ers wouldn't fix the crap even though there was a bullitin on it. I know they have some syncro issues, especially in my si tranny. I think the bullitin said to replace all the ones that grind. Just venting now, sorry!! :6

Re: How to fix synchros
 

Also, if you think going into a standard trans is easy and repairng, good luck, make sure you keep an eye on which way the syncros go back, shift forks, snap rings, clearences, this isn't an everyday joe job, its time consuming and if you don't have the tools, patients and some skillz, you will be one pissed off puppy when you put that sob back in your car. I would do a automatic over a standard any day of the week!!

Re: How to fix synchros
 

Your nuts! Theres no seals, pistons, valve bodies, clutch packs or teflon to deal with. I'll mess with a manual anyday. walk in the park.

Re: How to fix synchros
 

i can do anything mechanical, i just need to know how, and what tools. im sure its somewhere on the internet, as i havent looked but briefly.

Re: How to fix synchros
 

ATF in a Honda tranny = death to plastic bearing cages, like Redline MTL does.


turbo dave, I've never failed to provide info on tools needed.........yes it sometimes hurts me as a business getting started.

If you can build a motor, Honda manual trannys are a cake wake.

Re: How to fix synchros
 

There are plastic caged bearing in the MM6, huh, weird, never seen them get trashed.

Re: How to fix synchros
 

I used to see alot of dissolved plastic cages, ever single one was running Redline MTL.

Since I haven't seen anyone running it lately, alost less bearing issues :)

Now to kick Autozone's ass, I believe their new puter program suggests 75w90 gear oil!!!!!!

Re: How to fix synchros
 

That is a lawsuit waiting to happen

Re: How to fix synchros
 

lawsuit already started against an Advance Auto.......

Guy walked in and asked for fluid and filter for a automatic Honda, they sold him three quarts of ATF and the filter, printed off insturctions on how to change it.

he stopped after not being able to get the center section off the tranny.

Re: How to fix synchros
 

Haha...why does that not surprise me :P These days when I need a part from them I look it up on their site first and just hand them the part number...alot easier then standing there trying to argue with the idiots about what is really in the car.

Re: How to fix synchros
 

when they argue, take the keyboard away and look up your owns parts, point to the part number you want.

Works at my local Honda, I had my full order entered, knew what warehouses the parts were coming from......and the parts manager walks by......"Hey Clint, this is the self serve line right?"

BTW jago, I'm quite sober tonight, but the shakes SUCK!

Re: How to fix synchros
 

my third gear has grinded for 3-4 years and my car doesnt like to go into fourth unless im mashing on it ... my tranny loves me

Re: How to fix synchros
