The reason why we recommend Torco is along the same lines as why synthetic ENGINE oils are recommended for their better performance. The issue with transmissions is that UNLIKE engines, they DO NOT have any filtration and are generally not cooled (automatics being the exception). While a typical D/B/H/K engine takes about 4 to 5 quarts of oil, their respective trans take no more than 2.5 or less. So unless you're adding a transmission cooler and/or increasing the capacity, using a quality fluid designed to handle the heat while on track is essential!

[@Jason56B]

MFactoryTV What are your thoughts on the Torco MTF vs Torco syncrotec MTF made for Honda/Acura? I personally run the Torco MTF with their friction modifier on my Bseries LSD trans

[@MFactoryTV]

@@Jason56B is your B series LSD a helical or clutch type unit?

[@Jason56B]

MFactoryTV Its a b16 trans with kaaz 2way

[@MFactoryTV]

@@Jason56B if you're using a clutch type diff and you're on the track, it's best to use straight RTF and the Type F friction modifier. An alternative that we approve of is motul competition 75w140, also for track use. For street use, the Torco MTF plus friction modifier is fine.

[@S2GUnit]

My 1994 NSX has an OEM Torque Control Differential, wet-clutch type of differential. Would I be able to use Synchrotech or regular Torco MTF for daily driving to improve the smoothness of my shifts?

[@rogergranville6668]

Honda Street Garage did this exact type of comparison he always recommends synchromesh. He said every time he used Honda transmission fluid his synchros ended up going out because of hard driving. Once he used synchromesh fluid he never had a issue again.

[@BoostedPastime]

Syncromesh worked for me

[@LoveLikeaHurricane]

Amsoil?

[@thinkforyourself5672]

What brand? I've heard any Synchromesh fluid you use is made for transmissions that are higher mileage and have some wear on them. Not good for new motors but I don't know if that's true

[@joemcdonald9270]

From my experience working on cars, it really doesn't matter what fluid you use. As long as its clean and serviced for the conditions your using your car in. For racing I flush and change it way more often than in my street car. A lot of of what is said is marketing anyways.

When I spoke with a builder at synchrotech after purchasing their carbon synchros for my Turbo D16 they recommended their brand torco mtf which has synchrotech on the bottle they also said or you can use Honda mtf now I explained that I'm running a built turbo setup and he said Honda mtf works perfectly fine and that synchrotech has their own formula made by torco and he never said it was better by any means also I know numerous people with built Honda's that all run Honda mtf with zero issues at the end of the day Honda recommends Honda mtf period and you don't need to Google search it cause it's proven and specifically designed for Honda transmissions

[@elliot438bcfcVTEC]

Always used Honda MTF3 in all my Hondas. Pretty much all UK guys do the same even in track cars with aftermarket diffs. I always tuna magnetic drain plug too

[@clayglenn6513]

Theres a gentleman who has been working at my local Honda dealership for a very long time and I've asked him before what's best to use and he claims when honda makes the new fluids its engineered to work just as well with the older manual transmissions. I dont know for sure but that's the most I've been able to really find out

[@cbdreamer1709]

I put 10/30 in my manual cb7 and it seems way better than whatever was in there. Just don’t use synthetic. I read torco isn’t that good in cold weather and it’s great in hot weather. Great topic!

[@5PYZ3R]

Honda used to recommend 10w30. The manuals also said this. At some point I think in the late 90's regular engine oil no longer used zinc. Zinc is an important additive for transmission oil. Honda MTF more or less is just 10w30 with zinc.

In my opinion, close your eyes and pick one...you cant go wrong with either. Your engine isnt making enough power, even with you abusing it, always on high rpm both fluid will do great. Just my opinion. 😊

[@MODeration_nXS]

I use torco because of the mfactory components in my civic trans. I liked it so much that I use torco in my integra too. It's a stock ls trans but the torco feels like more accurate shifts.

[@nickburrill691]

what is an accurate shift

[@MODeration_nXS]

@@nickburrill691 when the synchros be synching and then you feel more confident with high rpm fast shifting. I've never felt so confident with quick shifts in my integra. :D

[@nickburrill691]

@@MODeration_nXS hell yeah brother

[@FinalDriveshow]

It’s just a matter of personal preference. The same can be used about Synchrotech versus OEM transmission gears. Some say Synchrotech all the way while others swear by OEM. All you can do is pick one and see if it works for your needs.

[@vanquishstorm3806]

I've used RedLine MTL for years on my Integra ls transmission and never had any issues though it wasn't used in a racing setting. For my next clutch job I will be using Penzoil Synchromesh.

Also I live in Socal and have physically been to synchrotech numerous times for many years

[@gustavocastillo9954]

I know older Hondas used engine oil for the transmission before Honda came out with their transmission fluid. In my case with a Prelude Type SH, Honda recommends genuine manual trans fluid, and automatic trans fluid for ATTS

[@justinn7777]

Can I use 10w40 semi synthetic as a gear oil for my honda civic 2008 ?

[@isnowyazn]

Uhhh, is no one asking why people are running a GL-5/6 rated gear oil (Torco) in a factory, GL-4 rated, Synchromesh specified gearbox….? I don’t think ‘newer’ Honda gearboxes were ever made to be run on GL-5 fluids either, hence Honda/Acura still sticking to their OEM MTF/gear oil (more of a ~GL-3/4 rating). Torco RTF (“GL-6” rated) is an even MORE aggressive gear oil than Torco MTF, and supposedly, it has a different additive pack, compared to the ‘typical’ GL-5 rated gear oil/manual trans fluid. Idk, but I drove a (performance) shop’s car that supposedly “built” an older B-series 5MT and a newer J-series 6MT, and both were filled with GL-5 Torco. They did not take more than like 1-2k miles before feeling ultra notchy/“scratchy” while shifting, not to mention the 75w-90 weight being too thick for the gearbox, unless it was driven and beat on until the fluid was overly warm or hot enough. They even tried Torco RTF (GL-6) after that, and it was even incredibly WORSE!!

[@forbiddenera]

1. Honda fluid has changed a few times over the years. Originally you would use engine oil in them. 2. Some MTF is too thick for Hondas. 3. Torco Racing MTF is best option for high rpm shifts.

[@h3xd3m0n9]

They hate gear oil i have bought a few cars that had 75w90 in them and can tell right a way lol

[@forbiddenera]

Gear oil can be bad but motor oil is rated differently than gear oil. "API viscosity ratings for gear oils are not directly comparable with those for motor oil, and they are thinner than the figures suggest. For example, many modern gearboxes use a 75W90 gear oil, which is actually of equivalent viscosity to a 10W40 motor oil"

[@brendansmith270]

Just put an itr 4.7 fd trans on my B16. I put Honda mtf in it, disclaimer it was rebuilt so it’s practically all new even the hardware. Even though torco is better I just look at it from price. Pay more hopefully replace it less or pay less and replace it more. I’d rather replace it more just to see how it looks. I personally also don’t short shift my transmission to all hell on track. Temperature is obviously the main concern but I haven’t had an issue yet on regular Honda mtf so. Both options are good just pick your poison!

[@lobuk516]

Torco RTF/ MTF blend has worked well in both my b series race trans and my k series race trans. All have clutch LSD and only see 10/10ths track use. OEM stuff isn't up to the task.

Torco told me at the end of this year they're releasing a Honda specific mix which is along the lines of 50/50 MTF and RTF. I'm about to do the same thing and do a 70MTF/30RTF mix in my R and see how she feels. No question Torco makes amazing fluids. Besides OEM, Torco, Amsoil Synchromesh and Motul are about all you hear anyone using. I've heard great things about the Motul Gear 300 as well. But I do know it's definitely thicker than OEM so in super cold climates it can be super notchy before the box warms up which always takes much longer than the engine.

[@spencersgarage]

I always use Honda OEM fluids, I even use Honda 5w-30 oil in my '91 Civic & '94 Integra GSR

[@allseeingeyezz]

i'm sure the new Honda mtf is good but it's so thin i can hear the gears clunk around, especially when shifting at low speeds. sounds pretty bad. just ordered some Torco MTF.

[@MolltoMotto]

I owned a Honda Civic for 6 years, and the first thing I do with the transmision fluid was a change, the manual said you can use MTF Honda.... OR full syntetic motor oil, I used full syntetic motor oil for 200.000 Km (124K miles) and I sold the car whit no issues on the gear box, engine or any other part. That was my "A to B" car, races are another thing but if someone have an honda to go from A to B in a reliable way, full sntetic oil or Honda MTF fluid are good

Use Honda MTF. Used Castrol 75w90 on my Integra S80 with LSD Transmission. My 3rd Gear Synchro was worn out before, but with this fluid I couldn't even get the car into third while on lower rpms. Changed back to Honda MTF3 and the 3rd gear grind was only on really high rpms. After that I rebuilded the transmission. My opinion never use any other oil then Honda MTF in a Stock Honda Transmission.

I guess coming from CX/VX.. but DX doesn't have short gears. not even close. the ex/si have even shorter gears and final, but even those are only comparable to an LS b series which are still considered long.
