I've used synthetic mobil 1 in my tranny for 1000 miles and learned synthetic doesnt allow the friction for the synchros to work in the way they're designed (which explains my very rough shifting), but Honda MTF is cheaper than GM Syncromesh is there a big difference between the two?

 

ive heard about this alot from the ef guys. one guy trying both the honda mtf and the gm stuff and he said the the gm stuff worked better

 

i'd use honda MTF in a honda transmission.

not that SM doesn't make for smooth shifts or whatever, but the oil is too thin to protect the transmission over the course of tens of thousands of miles. if tranny longevity is your priority, stick with the honda mtf.

 

Agreed. GM sm, from what I gather, is something you use when your tranny is already f'd up and you're just trying to make it feel better.

I used to always have to shift into second before shifting into first. I replaced the Honda MTF, and now I never have to do that, it just goes into first easily.

 

Penzoil makes GM syncromesh. You can get the penzoil version (same as the non-friction modified version) at autozone or whatever for usually 6 dollars a quart. That is a bit better than the 10$+ for the GM version.

 

GM syncromesh If you read on the back of the GM it says "it will not break down" Like butter

thermal breakdown isn't so much the issue as the fact that the fluid is too thin to begin with.

and, personally i don't believe that it "won't break down." all lubricants will break down over time...especially in a tranmission, where it is subjected to heat and shear.

 

How about mixing in 1 qt GM Syncromesh w/the Honda MTF?

Any tried Redline's 75w90 or MT90 fluids in their Prelude trans?

Don't mix fluids.

IMO, you should stick w/ a Honda MTF fluid until your tranny gets some miles on it and starts to shift bad and grind. THEN the Syncromesh will shine.

If you're having trouble w/ grinds, give the Syncromesh a shot; it helped mine tremendously.

 

Is there a time interval when it would be recommended to change the tranny fluid? I don't put that many miles on every year.

 

GM.

 

I've been running the gm synchromesh for awhile the guys at gm told me you dont wanna mix that stuff at all. This has been covered , many people on HT have made the switch from honda mtf to the gm fluid with excellent results.

 

ANYONE EVER TRIED THE ROYAL PURPLE SYNCHROMESH? IM ABOUT TO PUT AN EXEDY STAGE 2 RACING CLUTCH AND FLYWHEEL IN MY CABLE TRANNY (FOR A 1ST GEN B16) AND IM TRYING TO DECIDE WHETHER I SHOULD USE THE HONDA MTF OR TRY THE ROYAL PURPLE SYNCHROMESH? OH YEAH, MY TRANNY DOESN'T SEEM TO HAVE ANY PROBLEMS, I.E.: GRINDS, ROUGH SHIFTS, ETC.

 

Use the fluid a manufacturer suggests ie. MTF.

 

I've used Pennzoil Syncromesh, and Royal Purple Syncromesh. I can't tell much difference between the two. Both of them really smoothed out my older transmissions!

 

honda MTF

The new Honda mtf is too thin. It's good while it's cold, but once it's warmed up it becomes notchy. I've heard it doesn't do well on track days either, probably because it shears from being to thin. For mtf, I'd go with either Redline or Amsoil.

 

i have yet to run into that problem with it.

 

I'm using the new Honda MTF, better than GM syncromesh fluid IMO

 

im with blake and visine on this one. ive tried everything and at least for my drag racing purposes the new Honda MTF is great!

 

MTF, running it in my m2b4. Lovin' it.

+2

 

word up thanks 4 all the input people, i appreciate it sounds like im gonna b using the honda mtf

 

Honda MTF it does seem like it is a little thin, but no problems for me.

 

just remembered something...

with royal purple syncromax and redline my gears were blue which meant there was too much heat....with the honda MTF i didnt have that problem...actually come to think about it, i havent had to rebuild my tranny since i switched!

oh yeah...i run Quaife lsd....but if you have something like a KAAZ lsd then you have to run their fluid which is just GL5/80-90 but with additive....but yeah thats a whole other thing.
