has anyone used the GM Synchromesh? i heard that it does wonders on eliminating grinding on the gears.

Just wondering if any of you guys have used this product and how you like it.

thanks

 

yup, works great, no problems whatsoever.

 

YES i use it and have used it for.... 2 years and LOVED it. I use to have a grind from 4th -5th and i added the GM Syncromesh and it eliminited the Prob! :-) I SWEAR by it!

 

Where would you purchase this? I think i'm in the need of it, b/c my gears grind from 2nd to 3rd.

any gm dealership, it didn't completely eliminate
my 4th to 5th gear grind but my car has 202k on it
so i'm pretty sure the synchro is just getting too bad

 

Just go to your local "GM" dealer. (Chevrolet) to there parts counter and tell that you want the Syncromesh. There might be 2 kinds... You don't want the "anti-shcok" Just the normal round bottle.

Yup! Great stuff. It's about $10qt. Worth every penny!

 

thanks for your inputs guys... ill try it out soon

 

there is a friction modified version and a normal version , why woudnt u want the friction modified?

 

anyone ever tried this on an auto tranny....my girls is starting to be a bitch

 

GM Syncromesh is not an Auto Tranny Fluid it's a manual tranny fluid. I have no clue if they make one for an auto.

You don't want the friction modified version because it is too much for the synchros to handle. I don't know how to explain it but it will make them sorta slip if you know what I mean at all.

 

Kwik Kar Lube & Tune here in The Colony, Texas will drain your fluid and refill it with GM Synchromesh for $35 total. Took the guy about ten minutes to do the whole job on my Si. Normally a manual trans flush and refill is $25 so it's an extra $10 for the synchromesh.

Call around local lube shops to see what they charge. They buy the stuff in large quantities so it doesn't cost them $12 a quart.

So you use this only? You don't mix it with the regular tranny fluid?

 

There are two posts on this already.Regular GM synchromesh is nothing more then Pennzoil motor oil with additives. The problem with the friction modified version of synchromax is that it accelerates synchro wear due to the friction modifying additive and the fluid being too thin. This equates to too much friction and synchro clash (grinding). The Redline MTL accelerates synchro wear because of the exact same reasons. I would recommend just putting in Pennzoil motor oil as it will be friendlier to the seals in your tranny, and is the exact same minus the additives. Just so you know synchromesh has been around since the mid 1960's.

 

penzoil???? **** that im glad i didnt use this product

 

Sort of right...

It's not regular penzoil though

Actually Friction Modifiers lessen the friction, not accelerate it you jackass....don't listen to this guy.

I agree with Gerhard_001. Post up some education on friction modifiers before you call him a jackass...

Sure! How about I read what it says DIRECTLY from the back of the quart?

"Gm Synchromesh Transmission Fluid is a semi-synthetic lubricant for use in manual and 1500 transmissions. It is highly friction modified to REDUCE TRANSMISSION COMPONENT WEAR."

How Gerhard goes out and trys this stuff before he knocks it. There are about 50 users on here loving it, and he is one of the only people who knock it. But, has he even used it?...

 

Maybe I should have been more clear on what I agree with... 1st, the synchromesh works killer. 2nd, Friction modifiers do add or lessen friction, but in some casses the friction modifier can be detrimental and cause syncro failure. Friction to a point is needed to slow synchros down. Some lubricants are too slick by them selves and require an additive to make them "not as slick". thus a friction modifier. The trick is to get the right amount of friction and the least amount of wear. I hope that makes more sense than what I stated previously. Is it the same as penzoil? HELL NO.

 

In this case, "Friction Modified" means additives to reduce friction, therefore prolonging transmission performance/life. I was just pissed because Gerhard is dead wrong in this case. Again he doesnt even use it. Let him post in the ITR forum that GM Friction Modified is detrimental and it doesn't work.....he'll be set straight.

 

GM Synchromesh works amazing...

I used to run OEM honda MTF, then tried Redline MTF, then the Synchromesh and liked it the best. It also cured a serious case of 5th gear grind my tranny had. And the shifting is noticably smoother then with the other fluids...

I give it a as do most people who have tried it. This stuff has been around forever and has been a trick of the trade for a lot of car enthusiasts

 

Its good stuff... Im currently using it in my 98 'lude...

Going through the gears its noticabely smoother

 

I am sorry that I do not believe what everyone else says and just blindly jump on the bandwagon. Click the link down below from Redline, A synchronizer operated gearbox has to have a level of friction in it to operate. You are a uneducated and have no idea what you are talking about, friction modified is modified for friction because that frictional energy is used to engage synchros without clashing which is exactly what gear oils do if they are too slippery. Gm synchromesh friction modifed was designed for GM and Chrysler vehicles becasue they provide a level of friction needed for 'thier' gearboxs to operate without gear clash (synchro wear). And are safe on thier seals. This seems to be a problem with alot of HT members, you throw out petty insults because you have no idea of what really is going on or how stuff really works, and somebody actually happens to have knowledge due to research. 'because I read it on the label' who cares, the label is in regards to GM and chrysler it provides friction so these trannies can operate without wear, this doesnot pertain to Honda trannies. If everyone wants to throw thier money away go ahead I offered an educated statement and stand by. Just to clarify the friction modifed synchromax is the propriety blend, the regular sycnhromax is nothing more than motor oil with a few addivtives.
