Hi all, i just picked up a bone stock 99 Integra with 170k, and the 1-2 synchro is bad. What are my option to repair/replace? Im in Toronto/Vaughan.
thank you

 

easiest is just swap out to another unknown condition trans. but it would be great to see a trans rebuild thread if you are up for it.

 

why would you bother installing another transmission of unknown condition? That's just POINTLESS.

OP, just remove your current tranny and take it to a reputable shop/person to replace the syncrhro's.

 

that was the point of using unknown condition.

 

Idiot.

 

anyone know a ballpark cost to getting the trans rebuilt?

 

About $3,200 but also depends on what you want done and who does it.

Talk to my guy Joel at ,

 

$3200??? Are you nuts? Your 'guy' sounds like he is ripping you off.

Learn to do it yourself. Disassembly takes 2hrs at most. Inspection takes 2-3hrs. Ordering parts takes an hr. Putting it back together takes no more than a day if you are being ultra cautious.

It's like $150 for all new synchros from synchrotech.

​​​​​​90s Honda manuals are so easy.

 

$3200 lmao. I wouldn't trust anyone who doesn't have a presence on this forum anymore. @Aquafina what does $3200 cover?

 

Synchrotech carbon master rebuild kit (all bearings except differential, seals, shift boot, snap ring, carbon-lined synchros, synchro springs, hardened selector sleeves), differential bearings, Synchrotech 2nd gear, Synchrotech 1/2 and 3/4 hubs, Synchrotech 3rd dog teeth, OEM 1/2 shift fork, OEM 1/2 friction dampers, OEM crush washers, labor (including media blasting the case). That leaves you with $1,431 left over out of $3,200. Shipping from/to Canada will be a bit expensive though.

 

It needs more than synchros.

 

​​​​​​
Do you know this guy? Why would he NEED more. Especially all that sight unseen.

Carbon synchros eat the gear cones and don't provide any better shift experience. You will wear out the more expensive gears faster than the cheap synchros. I would recommend against it. What makes you think carbon synchros are the way to go?

What you quoted is the maximum expensive way to go for sure, a good example still way under budget of 3200

 

My "Guy" wouldn't use $150 syncrotech syncros on my caliber of build and it's not as easy as reading a manual and pulling things apart and putting it back together!


Maybe I should of been a bit more specific, That quote was for my Type R trans fully built! M factory LSD/ gears with 4.7 FD etc. so like I said it depends on WHAT you want done! Fort a basic rebuild it won't be near that price trust me!

 

No, I don't know him. He needs more than synchros because along with the synchros, the selector sleeve, hub and dog teeth are worn. 50/50 the fork is worn past the service limit as well. Carbon-lined synchros do not wear the gear cones faster.

Im going to drop a replacement S80 trans in, cross my fingers that its ok, and take apart the one i pull out and have it rebuilt.
Another question, will coilovers from a same gen civic coupe fit the integra?

 

Not the rear.

 

I paid a similar price for ManualGearboxLLC to do literally an identical trans build for me.

Granted that was 5 years ago.

 

I rebuilt my first transmission in 2006-7... I still have and use that transmission. I did carbon synchros in it. And the master rebuild kit, and hardened hub, and replaced 3rd gear with one that had more meat. I road race, and daily it, I put over 150k miles on it. The carbon synchros killed the gear cone on 3rd gear in about 30-40k miles if I remember right. So I had to buy another 3rd gear, and went with brass on that gear. Now this last rebuild, I swapped all the carbon synchros for brass because this time 1st gear cone was gone and had to buy a new 1st gear.. 2nd wasn't doing so hot either. I think I may have swapped that out too. 3rd gear cone still had good meat, just put a fresh synchro and spring on it. That's my main reasoning. Personal use.

I've rebuilt numerous other B series transmissions for friends as a hobby, none of theirs have killed cones yet. But they hardly drive theirs... A couple we did carbon because I thought it was cool still. No one can tell me they notice a difference jumping from one car to another for another reason.

 

Hardened hubs weren't available in 2007, nor were the master rebuild kits. The Gearspeed carbon synchros (Synchrotech wasn't even open until 2008) were brass synchros with a carbon coating sprayed on and they had issues. Synchrotech used the same type at first and had issues. They switched to a carbon-lining around 2011 or 2012.

I've got over 200k on my personal car with carbon-lined synchros (I track mine too). I've gone through two sets of synchros and the gear cones are still fine.

Compare the dog teeth of a brass trans and a carbon-lined trans after using both for the same track mileage and you'll see a difference. Honda and other manufacturers aren't using them for the cool factor.

 

I'm debating on replacing the synchros on my Del Sol since the transmission will be off for a clutch replacement/upgrade. From what I see, the brass kit is about $60 cheaper than the carbon. I did find a set of carbon for my S40 tranny for under $400.

 

What issues is it having?

 

Ah you are totally right. I had to look back at my receipts. Aug 2013 I did my first carbon master kit.

I guess I just had bad luck. The carbon never seemed to wear off the synchro tho. It was only the cone that lost material. Carbon is a higher abrasive so it should cause more wear, no? But tis the nature of race car things I feel. I just didn't see a big diff in notchiness, but my driving style includes heal toe and I don't power shift. I've rode on track with a lot of guys that don't heal toe; with such wide rpm changes maybe it is more noticable.

I didn't know any OEMs did carbon lined.

 

no grinding. Every once in a while it will be hard to go into gear like 3rd and 4th. Have to basically granny shift it and it goes in.

 

Best bang for your buck is to do the master rebuild kit. If you only get a bearing/seal/synchro kit and it ends up needing sleeves, you'll be spending a lot more. Of course if you can afford the downtime to inspect it first then order parts that is the best option. https://wd-r.com/shop/ols/categories/synchrotechd

 

Off topic what's a DOT Type R trans go for these days? It was purchased from the dealership as a crate trans.

I have one that needs a rebuild for the famous 3rd gear grind not sure if I should rebuild it or sell it as is.
