I have a 92 VX hatch with 134k on the body, not sure when the clutch was done last (if ever) but it still feels like it has a good amount of life. It grinds when shifting from 2nd to 3rd at around 5-6k RPM. It only started doing this a few weeks ago. It's a slight grind, nothing terrible. It won't grind at a lower RPM. I've heard this has a lot to do with clutch wear and synchros. I've also read quite a bit about Synchromesh MT oil and synchro grinding dissapearing. Have you guys had any experience with Syncromesh and has it been positive?

I put sincro in my tranny, and it really made a difference

 

Lots of people use it,

 

aka "Jesus Juice"

 

Worked for me, it was grinding so bad I used to skip third gear completely and feather it into fourth. When we put it in we were told it usually takes a couple of days to lube up everything. Havn't had a grind since putting it in. Its worth the $45.

 

i have the same problem man. it grinds from second to third when vtec is engaged in second. i just changed my tranny fluid with honda mtf. i'll try that gm synchromesh fluid next time.

 

hrm, I never knew that this was a commen problem, i thought my clutch was that bad. no other gears grind its just when i shift 3rd when vtec is engaged, that i grind.

I will have to also try this

 

23623-P21-315 #007 SLEEVE SET, SYNCHRONIZER (3-4) $162.83



this is the replacement part you need. totally kill the grind, dont bandaid it.

Most people dont need to change the syncros, if u try syncromesh and the grind goes away your good, but if theres not improvement then yeah, time to change the syncro's

 

its not just the syncro that needs replacing albert, its the syncro spring, hub and collar also!!!

wtf are u talking about? read wat i posted.

 

Synchromesh worked for me
But not for long because I abuse my car

 

Synchoromesh covers up the grinds really well.

 

that gives me a good idea of what I need to do. I wanted to hear some success stories before I bought some and put it in. Are you guys using the Pennzoil or some other brand? Curious...

like this dude said, it covers it up well, like a bandaid. Thats like a dog taking a **** and putting newspapers on it, it doesnt fix anything, just masks it.

I just hope you don't sell your car saying that the tranny has no grinds, thats all.

 

I have no grinds in my tranny @ all rite now, how will synchromesh work for me ? Im chnging fluif tofay
