Anyone ever used syncromesh??

[adams86lxi]

Hey has anyone used penzoil syncromesh??? I heard it works real good for helping bad syncros in hondas? But how much shoud i use? 1 quart with the rest regular oil? Or should i fill the whole thing with it or what??

Right now i have full synthetic 10w30 with about a 1/2 quart of lucas transmission fix.

Im going to try this im my transmission for now until i can rebuild it.

[Underdog]

If you're planning on rebuilding the tranny soon anyways I guess it wouldn't hurt. I'm not sure about the popularity of it in Honda's, but it's huge in the DSM world. I had a bad grind going into 3rd at high RPM's and was starting to get a grind everytime I downshifted into 2nd with my Talon. I replaced the fluid with Synchromesh at school and I haven't had a gear grind from anything other than fault of my own since then. I used just the Synchromesh.

[lostforawhile]

It shouldn't matter what kind of manual transmission it is they all work the same,gears are gears,they have brass syncros just like most other manuals.

[Busted_Blue]

DSM world is famous for synchromesh but it also works in other cars. Couldn't hurt to try.

[adams86lxi]

Yea, but should i use only 1 bottle of it or fill the whole tranny with the stuff??? Because this shit is expensive lol. Its like 7$ a quart.

[thegreatdane]

It's an additive, right? Then dont fill it up with it, only use the one bottle or whatever it says on the bottle. Do you guys in the US have the additives produced by a company called "Abcon"? Their additives are top notch quality. (and made in Denmark too :) )

no its not a additive its just transmission fluid.

Im probbaly going to put 1 quart of that syncromesh and the rest is going to be some synthetic 10w30 and lucas oil additive or lucas transmission fix. And ill let you guys know how that works out.

[pmpete]

Any experienced Honda mechanic will tell you just plain old 10W-40 Moto oil is fine. Heavy gear oil will not work in Honda trannys the tolerances are too tight and will burn out quickly.

You shouldn't use lucas oil additive with synthetics. Google for more info, but it causes them the oils to 'foam'.

Avoid lucas oil!

[speedpenguin]

Hey, that's good information, man!

[AccordEpicenter]

adam dont ever use full synthetic oil in gearboxes, its too slick and doesnt stick to the gears like dino oil does. If you wanna cure your syncro grind use straight GM syncromesh FRICTION MODIFIED (not the penzoil stuff, this stuff is only available at gm dealerships) part number 12377916 http://www.imagestation.com/picture/sraid95/paa6ad08fa9f816d6b962292468380555/fa229bfd.jpg

Bob the oil guy would disagree with you. Synthetics are the best thing since sliced bread.

[88Accord-DX]

Where the hell is Bob when you need him? LOL

Interesting arguments though.

[mkymonkey]

wow, and to think i was pissed that i forgot to add the lucas stuff to my motor oil today when i changed it. lol i wouldnt want freaking whipped cream in my motor...thats for sure!

finally accordresto...you do something for the community! thanks

[Mars]

Yeah! I ran lucas through my oil and it came out lighter brown and foamy.
I was sick beacuase i knew i had a leaking head gasket.

[tysn]

do they make anything like the sycromesh stuff for auto trannies?

[speedpenguin]

Yeah it's called automatic transmission fluid.

[Mars]

^^ :rofl:

:rofl::rofl::rofl:

Still there buddy? It's cool that you asked that, That's how you learn. Right now we're dicussing additives to put in manual trannies because normally you'd just put in engine oil.
Since auto trannies use specially designed fluid, there's no additives, because the standard stuff is already designed to do what it does.
And, as we've learned from this thread, it's fairly pointless to add stuff to the oil in manuals anyway. That help?
By the way :welcome:

[Mars]

They do make auto tranny fluid stabilizers. goto a local auto shop, they might have some.
The way ti works is it softens the bands and such in the tranny so it dosnt shift as hard. iunno how good that is for it, but it works.

You use engine oil in your transmission!?

[buds302]

i am fully against syncromesh! heres my reasoning....i started with one transmission. put syncromesh in it, the pinion shaft went out in it, i just thought it was bad driving. trans #2 put syncromesh in, input shaft bearings went out, trans #3 same thing, so now im on to thinkin its syncromesh, im on my 4th trans now, ive had it more than four months now.....the others didnt last a month. so im fully against the syncromesh

[speedpenguin]

You use engine oil in your transmission!?
Yeah, that's what you're supposed to do for a manual. At least for a 3G manual.

[gfrg88]

wait, so everyone on here puts regular motor oil in their trans????:wt:

[88Accord-DX]

I use sythetic oil, 10w-30. Looks like all the additives aren't worth a damn & one person had bad results with syncoshit, I mean syncromesh.

[gfrg88]

what about 20w-50??? does it have to be sythetic?? i never knew we could use regular oil so thats what im asking (i feel like such a n00b )

[89AccordResto]

Weird. Allt eh manuals I've used required manual transmission fluid.

[Mars]

ive ehard that motor oil works but tis better to use thicker stuff

[88Accord-DX]

Thicker oil should be the way to go. I used what was free, upgrade in the future. Had some kind of gear oil in it when I bought it.

[Fuzy Navel]

Hey, Just wanted to say this, I used Royal Purple Synronizer something cant remember what it was called and replaced my transmission oil with it 3 quarts i think, because my 1st to 2nd gear would grind at high RPM and it was hard to get it in gear it wouldnt just fall in... So i put that stuff in it worked really good for like 2 weeks and then it started coming back but im gonna get a new tranny anyways so i dont care but i do use royal purple oil in my car that stuff is fuckin sweet i think (I know oil is oil) but i think it runs alittle smoother and better with it

[89AccordResto]

Royal purple isn't all that and a bag of chips. Search for oil tests.

[speedpenguin]

Thicker oil should be the way to go.
My tranny's had motor oil in it, since I got it, pretty sure it was 10W-40. I might switch to something thicker after reading this thread, though, especially since 3rd gear is starting to grind due to the abuse my mom and aunt put on the car before I got it a few years ago.

[Mars]

I think i might pick up something like synchro mesh, my tranny has been grinding a little going into 3rd at higher rpms.

[Legend_master]

I used syncromesh on a tranny that was grinding first, second, and third. Now the tranny has no grinds and shift very smooth. I used 2 1/2 QTs, because you are suppose to completely replace your tranny oil. Also I never even heard of manual transmission oil, all I ever used was motor oil for a manual tranny.

[89AccordResto]

Also I never even heard of manual transmission oil,

Usually it's gear oil. But not engine oil. THat's just weird.

You're just weird. :D

you can use 10w30, but in honda trannies it tends to make them feel notchy. Honda MTF is the best stuff to use if youre tranny is in good condition. If you have a bad grind, i dont care what crazy ghetto bob says, syncromesh is the shit

Yeah. If I was going to flush my transmission I'd use the factory transmission oil. :cool:

[pmpete]

RTFM (Read The Fxking Manual) Honda specifies 10-40 MOTOR OIL. I changed mine this past weekend and added some lucas transmission fix and it seems to work quite well.
Honda as since switched to its own blend of MTF. Several folks I have talked to say it quite good and works fine in their G3 Accord.
I wonder what the viscocity of the Syncormesh is? Any body seen a rating for it?
Once again do not put heavy gear oil in a Honda tranny unless you want to kill it. It is a leading cause of the dreaded 5th gear failure due to the fact that it is too thick to make it all the way up to that gear from the pool at the bottom. Of course the leading cause of 5th gear failure is not having enough oil in the tranny.

Hope you weren't using synthetic.

http://www.bobistheoilguy.com/images/lucas/lucas.htm

[pmpete]

No I won't waste my money on that expensive shit. When good old Dino oil will do the trick with a little help. Beside if you have any leaks Synth will find a way to wiggle out them.
Paul

[cubert]

i had 80w90 in mine...only time i had trouble was when it was stupidly cold out and the 1-2 shift was a bit sluggish...but once the motor warmed up it was fine

[AccordEpicenter]

80w90 is wayyy too thick man thats heavy gear oil. I think syncromesh is approximatley 10w-40 ish thick, but it might be like 20w50 weight... i cant remember, its not gear oil thick though

[89AccordResto]

Thick oil would hurt your MPG I would imagine.

[Mars]

Holy crap...
My car was grinding into third pretty bad, and grinding on a lot of downshifts.

I just drained all of my old oil out and filled it with synchromesh (i found out penzoil makes the gm stuff, so i went with penzoild ebacuase it costs about half)

Leme say, its like having a new tranny compared to how it was.

The shifter 'clicks' into gears like a new car.
I love it.

[AccordEpicenter]

yeah, but its not the friction modified version. They say the gm friction modified version is a bit better. But see, this shit works. 89accordresto was banned? I knew he liked to start shit but what did he get banned for?

I dont know, but I looked through his last post and I dont see anything wrong. I know he useally says the wrong thing and talkes alot of smack about alot of people. Maybe it is coming back on him now :dunno: .
