The only thing about the torco mtf is that it will not work too well with synchros that are old and getting worn out. I put it in my own car and it started grinding 3rd gear immediately.

If the synchros are old and worn out, it's time to replace them. I would never recommending masking the problem by just changing tranny fluid.

I had AMSoil synchromesh 5w30 in a gsr trans from HMO, the trans grinded like a month after I got it installed, I'm not very happy at all, I drained the fluid like 7,000 miles later and the fluid was very black.. I switched to royal purple and it'd not doing much of anything either..
I'm leaning towards torco or redline

honda oem mtf.
the other thicker stuff is good but should be used for high hp cars i think. mainly for gear protection.
i used the redline for a while and noticed it needs to warm up a little longer before it goes into the gears better. also i had problems grabbing 3rd at the track with the redline stuff so i switched back to the oem mtf and caught each shift perfect everytime.
oh and them oem mtf is cheaper. lol.

Re: Redline MTL, Honda MTF, or GM/ACDelco Synchromesh Fluid?
Guys, just keep in mind when selecting a syncro fluid, it's not just a matter of brands (additive chemistry) but also a matter of weight. Syncro fluids go from ATF-thin stuff all the way up to 90 weight gear oils. Here's a list of brands and their weight in centistrokes (cSt) at 100C/212F :
ATF type: 6.0 – 7.5 typical
Honda MTF II 7.5
Royal Purple Synchromax 7.7
GM/Chrysler Synchromesh type: 8.5-10.0 typical
Torco MTF 8.35
Pennzoil Syncromesh: 9.08
Amsoil MTF (5W-30) 9.6
Red Line Oil MTL 10.6
Honda MTF I 10-11?
75W-85 Gear Oils: 12.0-12.5 typical
Specialty Formulations MTL-P 12.0-12.5
Castrol Syntorq 75W-85 12.0???
Nissan 75W-85 12.0???
90 weight Gear oils: 15-16.5 typical
Chevron Delo 80W-90 14.2
Royal Purple Max Gear 14.5 (Published: 21)
Amsoil MTG 14.7
Mobil 1 75W-90 15.2
Pennzoil GL4 75W-90 15.3
Red Line Oil MT-90 15.6
The list is a bit dated ... there are a few newer fluids I have not bothered to add.

i would like to know if anyone has tried the new honda mtf-3 or any of the newer gl-6 oils (another thing to point out is there is no such thing as gl-6 anymore...gl-1 gl-2 gl-3 and gl-6 ratings were discontinued in 1995) but people can still make and sell oils under those API ratings. (even though there is no governing body that will test to ensure those ratings are accurate)

We have use RedLine in a variety of vehicles and can not think of a single instance where it didn't make the vehicle shift better from Porsche Cuppes to even a beater Toyota 4Runner with auto to manual box swap - talk about extremes from racing to street!

Try it in a Honda, report back when bearing cages fail.

IDK Bone, Redline LW SP works great in mine.... H's have steel cages, BUT i have also replaced counter bearings with plastic caged honda OEM replacements (not sure as to the rhyme or reason to why sometimes you get plastic and sometime steel when ordering the same part number)...
Never had a problem. Then again, getting the trans up to temp (IE warming the car up) probably helps I would think ...

Re: Redline MTL, Honda MTF, or GM/ACDelco Synchromesh Fluid?
We have and no issues. Maybe our guys aren't using as hard as yours? Under what conditions are you experiencing failure? How built are the cars? How are they used? None of our guys drag race if that is the circumstance. Also, none of our guys are pulling 500+WHP (by far I am the highest with mid 400s).
