GM Syncromesh

Post by Motts »

I was wondering if anyone on here is using it? I searched but nothing came up. I havnt checked the board in quite awhile, I think its changed alot since last time I was on, so I hope Im posting this in the right area. Anyways, Im thinking about switching to the GM Syncromesh for my 2001 C5. The motors in a EH and Im having all the usual ITR tranny problems (first gear issue and a little whine) and I know some people on Hondatech that have switched to this and it solved their problem. So is anyone here using it?

Also, could some either tell me, or give me a link on how to change my transmission fluid over to the new stuff. The proper way to clear the lines and bleed it. And do you reommend the Friction modified stuff over the other stuff? Anyone have a part number by chance? Any help is appreciated. Thanks in advance.

Thank God for GM! They make something worth buying! lol.

My situation with my gears were like this, 3rd grind like a mother at lower RPM's and during racing RPM's. I would have 2 wait about a good 1.5 to 2 sec's to shift into third or I would just skip into fourth from second gear. I've changed tranny fluids 3 times on my R already, started with Royal Purple- no change in status, next was the original Honda Tranny Fluid- a lil bit of a notice, but still had the grind, then one of my race buddies adviced me of the SyncroMesh. Result, after about a week of just driving and just shifting normal gears. NO Racing, I repeat no racing. My third gear was a miracle. Now I can bang gears like I was racing at the track & street like I never had a problem with the tranny to begin with.

Hopefully this helps you out upon making a decision. If you want to get proper info about how change out tranny fluid, just stop by your local Acura or Honda dealer. They will be glad 2 give you a printed lay out of the tranny & give advice. One big recommendation, when U change tranny fluid consistantly, the drain bolt & fill bolt washers on the tranny need 2 be replaced or your'll have a leak. The washers cost no more than a buck for both.

Good LUck!!

Thanks alot. I decided to go with it. After alot of Honda Tech research my decision was pretty much made up for me. I also found some awesome websites on how to do the changeover. Once again, CSpeed amazes me!

Ill pick up the new crush washers when I go and get my new LCAs. Thanks again.

Wow, one reply and you buy it....

It depends on what your car is used for. If it's used for the track, then I definitely would not buy it and put it in my car.

What R U getting at? Do you have any experience with experimenting with different types of tranny fluids? How long have U had UR R for, tell me how many times have U had tranny problems & that U went to find a solution to cure the problem? Like the man said on his post, he did his research on the Syncro-mesh. If Ur a honda guy and U care about ur R, U'll know what 2 use and Not. I've had my R for about 3 Years now and have been racing track, street, & drag w/ da syncro-mesh and have never had a gear problems. Read before U talk next time. & Trust me, I'm not new 2 the forum, so don't act like U know what's best for everyone. I only offer suggestions and let people know what my past experience's have been with racing & products. They make up their own mind so they can make da best investment for their ride! Peace! & Always keep da pedal Floored!

P.S. I'm starting any beef, I'm just making a statement!

That is so hard to read....do you talk like that? How old are you?

Anyways....here is some great info from Team-Integra.net....Michael Delaney posted the following (BTW, he has experience and doesn't go around saying "It iZ maDD shIAt Yo!");

"well since few people heed my "always consider the context of the opinion you are given before you make conclusions" and like "opinions" especially if they are presented with bravado (but no facts between comparing 2 products: 1 owner, 1 product, 1 opinion, different conditions->race/strip, street tranny temp. & mileage interval change), here is the most precise , coherent opinionated explanation from someone with the "correct" experience (without the chemistry and comparative experience by controlled observation or even if uncontrolled at least with some context):

Before you guys jump off the bridge, I hope you realize the reason gear oils like Redline MTL, GM Synchromesh, NEO 7W (synthetic) and all the rest work so good is because they actually INCREASE friction, making the syncros 'crash' faster, with less grinding. It does this at the expense of synchro longevity, of course. This is not exactly news. However, many ppl consider this tradeoff to be well worth it. Just bear in mind that you aren't doing your tranny any favor by running any of these oils. You can't have it both ways. Less friction makes the synchros last longer, but you will get some 'grinding' when you shift. More friction makes the synchros work better, with less grinding, but it also makes them wear out faster...

If GM Synchromesh works better than anything else, and I'll have to take your word for it - having never used it, all that tells me is it's also the hardest on your synchros. Don't go into these blindly! It's a cruel world we live in, isn't it?


--------------------------------------------------------------------------------


opinionated but factually correct.

I expect the wave of GM Synchromesh bandwagon jumpers who also race these trannies hard will result in us having a future wave of posts stating :

"I can't get into _____ gear (usually 3rd). Help!" or "My shifter is popping out of gear. Why? Help!"

If anyone really wants to trade off then blend your tranny oils until you get less grinding but not 100% synthetic. If you do a lot of high heat runs, use the right MTF for it. And for God's sake , change the MTF at the recommended interval (if not earlier).

You know the racing guys have already tried ATF in manual for short term racing use. It shifts like butter but it's a good thing that they know how to tear down a tranny and change it and re & re (remove & re-install) it in less than the time in between qualifying sessions on qualifying day.

It goes something like this:

"I had Honda MTF in my tranny. It was grinding. I added Synchromesh. It stopped grinding. It's great. Now my shifts are like butter. It's the best. Get it."

Had that person just done a scheduled Honda MTF change he would have gotten the exact same result (if he dragged out the change interval).

It's not just any wear. It's synchro wear that leads to the need for premature replacement of the synchro and collar (i.e. the hassle of pulling your tranny and taking it apart to replace)...that's what we are talking about. Not just any little bit of wear in some nebulous place in the tranny. Remember the synthetics are as thin as ATF and you get nice buttery shifts with ATF in a manual tranny. Problem is the tranny doesn't last long"


I'm sure you know what you're talking about as you claim, since you've torn down transmissions, right? You probably haven't....And I'm sure you already knew everything that I just posted, right? Doubt it. You go on what others tell you..."it shifts so nice, get it!" And then you get it and you think it's the best thing in the world....that's hype.

Before I go onto answering any of your uncalled for question addressed 2 me on the last post. U never answered my questions back? How long have U had UR ITR for? How long have U been racing? What's your experience mechanically w/engines & tranny's. Driving or Racing experience or U just a first time ITR owner?

Look I'm not trying to start a flame war! If U had read my post carefully, English is spoken, sorry I speak real technical. This is my past experience with racing w/GM Syncro, there is no better cure in the world for stock ITR syncro's. 4 Years of racing competition is my experience w/ testing my limits on rides- All motor, NOS, LS/Vtec, & B18c5r engines, been through all types of fluids- 2 Years w/ Syncromesh- on the B18c5. I judge my performance by experiencing what's going on w/ my own car on a daily basis and tunning. I'm one of those who listen's to great advice from mentor's, observe the situation, and solve the problem to fix up my ride properly. I'm still learning as day by day goes by. I still don't know everything that there is 2 know, but that's what school is for. And I guess that's why UTI is where I'm headed 2 next for rest of my education. So I hope I answered UR question about who I am and how old I might be. Experienced enough.

Oh yeah.....just 2 let U know, it's kind of rude of someone 2 ask how old they are and for not know much about the person. Like on my 1st post, MOTTS understood what I advising him on the Syncro mesh, I like talking about what products I've had great & bad success with. Also for everyone sake esp. mine, please stop posting pointless reply comments about a topic, after it has already been addressed by Trey or anyone. It gets annoying 2 reading at times. I post on this forum to offer suggestions and 2 chat about cars, not to post lil minor reply's about nothing....hint! Word from the wise!

Take it easy bro, good luck w/ ITR!

Still flooring mine to the pedal all day!

B

P.S. Please re- read carefully before U reply back! Like I said I'm not trying to start a flame war. It's just annoying when someone has to post an unnecessary comment about a subject. I only offer words from experience.

Your experience is "I put it into my car and it stopped grinding" that's your experience. Your experience isn't longevity which is what I'm addressing. I will take the notchiness of the HMTF in my tranny than put GM stuff in and have buttery shifts while compromising the longevity of my synchros.

Maybe you should take your own advice and read my whole post.

I still say your grammar is pretty funny....you can't type out "to" you have to put a number? Hehe...

Answer the question? Do you own a ITR and how long? Because a lot of Honda guys over here love the GM Synchro mesh. Have you tried it? If not why talk about it and stop talking about what other people say on other post. It seems to me that you can't figure out what to say on these type of post. So you take other peoples comments and post them like you said them or try to at least. The guy is just trying to see if it helps or not (and it does) so just stop talking and walk away before I report you to Budman for Flaming.


Also who cares about grammer? It seems to me that you can read what he had to say! :lol:

I hate to see threads turned into a flame fest, and honestly its aggrivating when you see someone post a comment like "How old are you?" or "Your grammar is horrible and that means your stupid." This post has definitly gotten out of hand, but maybe I can add some good information to it, so its not a total waste.

Like I said before, "After alot of Honda Tech research my decision was pretty much made up for me. " So here are some helpful posts, taken from the ITR section of Honda Tech which is a very valuable resource if you like to learn, like I do.

http://www.honda-tech.com/zerothread?id=641177
http://www.honda-tech.com/zerothread?id=620135
http://www.honda-tech.com/zerothread?id=449756&page=1

Also, I ran across the thread with your little quote. Well if you read later in the thread he says, after much research (apparently):
"To be fair, I would say (now) that GMS FM will probably not hurt a Honda transaxle any more than any other performance tranny oil. It is certainly not as bad as running a API GL-5 spec oil in it."

If you do some searching of your own youll come across many people who have been using the Syncromesh for quite awhile and have had no problems. You will not however find anyone who has had problems; not from searching at least.

Hope this has been some help.


**edit - Ill be switching soon. Just need to find the cheapest place. Ive been told to try here = http://www.gmpartsdirect.com/**

How am I flaming? I just made a comment that it is hard to read his typing...and it is....

Obviously a lot of you haven't read the info I gave you, which is fine with me. If you want to try synchromesh and mess up your synchros, be my guest. You have no idea what you are putting into your transmission, you are just putting it in.

And, the last time I checked, someone's knowledge was not based on "How long have you owned your R?" That is the most baseless question I've ever heard. It wouldn't matter if I've owned one since they first came out in 97 or if I just bought one yesterday.

Read what I posted and not what someone who knows nothing of what they are talking about says "Yeah, the shifts are so much smoother, BUY IT!" That is a NOOB at it's finest, because that's being a slave to hype.

Your tranny, your money....not my problem. :D

P.S. Go ahead and PM budman and tell him about this thread. I'm the only one who has given any concrete evidence and has not gone on hearsay or hype. I've given factual, scientific evidence. No hype here.

I got a friend with a Eg hatch with a swap B16SiR motor and he's been running the GM Syncro Mesh for at least eight months now and he hasn't had any problems with his tranny at all. The Type R(Daily Driver) has had it in for at least 4 months now and it seems that all the problems went away. So I say money well spent.

Give me some proof saying that the GM syncro mesh is bad for your
tranny. Because this post right here seems to say that GM Syncro Mesh is worth using in your tranny.- http://www.honda-tech.com/zerothread?id=641177

And stop trying to prove your self cause it seems that we proved you wrong on what you think about the GM Syncro Mesh.

Or just go on Honda-Tech and ask if the GM Syncro mesh is bad for your tranny.
