can anyone tell me if syncromesh will help my 2nd gear grind, and also how much i need to put in my ls tranny?

 

Ive seen syncromesh cure some tranny grinds and ive also seen it make them worse. You drain all of the fluid out of your tranny and refill with syncromesh.

I use it and it makes my tranny shift much smoother

 

so you fill it back up with only syncromesh no oil, and how much some say 2.2 others say 3 qts.

 

Yea, you fill it with only syncromesh. I park the car on level ground and fill the tranny until it runs out of the filling hole.

 

If you're going to give this a try, be sure to pick up the Friction Modified fluid. And don't expect it to "cure" the problem, just help mask the symptoms.

yep this is about the only good think i can say about USDM GM is there trans oil

honda needs to wake the hell up and realize there honda new and old MTF SUCKS!

GM synro mod is the best trans i have ever USED period!

 

these honda transmissions spin alot faster than gm's transmissions. Thats why they use motor oil instead of gear oil, if the oil weight is to heavy it can cause enough friction to damge your bearings and synchros. Honda trannys are redicoulsly easy to work on. just order new synchros from honda get you a three jaw puller and fix it. synchromesh is just going to make things worse in the long run.

On the contrary, I've read very good reports regarding the newest formulation of Honda MTF, and even the original works well, assuming the transmission is in good shape to begin with.

 

Honda's ATF sucks ***. I've used MTF since new, and never had a prob. And generally any kind of grind or crunch means something is broken inside the trans.

 

thats not always true, you could have bent linkages that no longer have the right throw length or angle that cause you to grind a gear, throwout bearings and pressure plates can screw up synchros real quick when you have einsteins that think they're just adjusting pedal throw and stiffness but they end up leaving the clutch engaged all the time. and of course some people just suck and cant drive...etc. I dont use honda's MTF, I use mobil 1 10w30 in my honda trannys, I used to use royal purple but I think mobile 1 works better in the trannys.

On the contrary indeed!

fully rebuild trans right down to a new magnet in the case and fill up with the NEW so called improved Honda MTF bullshit and guess what trans feels like a rusty old knife!

SO i drain the Honda MTF bullshit and fill with NEW GM sync mesh modif and guess what???

feels smoother then when i am in bed with a girl and i am sure you can guess the rest

oh and one more thing credit were credit due it was YOU sir who inspired me in an old thread to try this "Jesus oil"

oh and never had any luck with royal purple in the trans either or redline or anything else other then "jesus oil"

Something doesn't sound right about that situation. Remember, Honda fills all their transmissions with Honda MTF from the factory, and if it caused them to feel like rusty old knives, there would likely be a few complaints along the way.

Yes, when a transmission is exhibiting certain issues (usually related to failing or damaged synchros), the Synchromesh FM has often proven to help reduce the symptoms. On an otherwise healthy transmission though, you shouldn't be experiencing problems when running the new Honda MTF.

OK

shall we say under "race" conditions i will give you that much ok honda MTF works fine UNLESS your under race conditions then i have found it to be a better choice going with GM sync mesh modif

i stand corrected sir!

 

If you find the GM stuff to work better for your particular application, by all means, stick with it.

As for your apparent sarcasm and generally poor attitude, I'd suggest losing that.

If ever a man was more miss represented sorry you feel that way none of which was intended...

 

No hard feelings, just a misunderstanding.

I can vouch that GM Syncromesh can destroy a transmission. I had an f22 tranny hooked up to my h22. Filled with syncromesh and the transmission started making a rattling noise for no reason. It started to go downhill and get louder as soon as the "WRONG" transmission was put in.

 

What are the latest findings then? Is GM syncromesh with FM safe to use on a newly rebuilt tranny? I just had mine rebuilt and was planning to change out the fluid. I will use Honda MTF if it is now better but that is what is in there and I have a high rpm 3rd gear grind. I am thinking about using the GM stuff... In the past I used the penzoil and it seemed to work fine.
