Manual tranny fluid for honda

[teaelle]

I have an Integra Type R tranny with LSD, which MTF would you recommend?

Amsoil Syncromesh 5W-30 (syn)
Motul Gear 10W-40 (syn)
Redline MTL
Honda MTL
10W-30 Engine oil

I have tried the Amsoil on my older civic and the grinds went away, herad good stuff about it

Redline is very good but they don't last long

any good recommendations? thanks

Amsoil, hands down.

 

[ThirdeYe]

Amsoil or Redline.

I'd use Amsoil. All of their chemicals are top-notch.

I am currently using Redline MT-90. Shifts like butter once it's warm.

Although the shifting felt horrible for the first 300-500 miles, I found the new Honda MTF (green label w/white cap) to work the best so far in my S2000. The old MTF was not very good at all. GM synchromesh FM works very well, but shears down quickly and only lasts 7-8K miles for me. I will continue to evaluate Honda's new fluid for longevity, before proclaiming it the preferred fluid. I also have AMSOIL MTF and MTG on the shelf to mix for my tranny if I need it.

I have seen where someone recommends amsoil mtf and mtg 50:50 for the tranny. What does that do for you?

 

[INDYMAC]

It brings the viscosity into the 10W30-75W85 range. Not too thin, not to thick for a Honda.

I don't recommend this. MTF is fine and matches the Honda MTF pretty closely. But maybe in a warm climate, you'll get added protection. I run a MTF/MTG mix in my Volvo 855 M56, and it works great.

I've used Red Line MTL in my 84 Civic wagon almost since new. When I bought the car I took it home and changed the engine and transmission oil and used Honda transmission oil. It was at 100 miles or so. I think it was about 2 years later that I started using RL MTL. I did rebuild it at about 290k miles but that was because the roller bearings started to make noise. These are contact bearings and will wear out no matter what you do. The important thing was the gears, syncros and shafts. They were just like new. I'm now at 492k miles and things are just fine. Be careful about rebuilding your transmission. The dealer would not sell me just bearings and seals. They wanted to sell me the gears and syncros, too. They said that's what they always do it and that was from several dealers. I when to a bearing supply company and they knew exactly what I needed and were happy to help out.

u can just get the bearings from any auto parts store, it's a common problem for honda trannys

Anyone know the weight (cSt) of Honda MTF II?

I initially tried Amsoil Synchromesh,and then Redline MTL in my 2004 Honda Accord Manual transmission. I felt both were a slight improvement, although the shifting with the Amsoil seemed a bit stiff to me. I looked in the 2003 Accord manual(wife's car, which is thicker and has more information that the 2004 manual that came with my Accord.I noticed they recommended a 10w30 or a 10w40 oil as a temporary replacement for their manual transmission fluid. I remembered Molacule mentioning a lighter viscosity in manual transmissions did not always equate to smoother shifting. I also read people mixing the Redline MTL and Redline MT-90 in transmission with great success. I did that with the Accord. I (meaning the mechanic who works on car) added one quart of MTL with one quart of MT-90, and then a topoff with MTL. I have about 18K miles with this elixir and it shifts significantly better than Honda MTF, Amsoil Synchromesh, and the Redline MTL by itself. It is smooth and has maintained excellent shifting quality in all types of weather in the last 18k miles. I would heartily recommend this for people with a similar transmission.

 

[MolaKule]

The viscosity of the Honda fluid ranges from about 9.8 to 11.5 cSt, depending on the lab.

The following fluids have equivalent viscosities and are rated GL4: Honda MTF, Castrol Syntorq LT, and Nissan MTF (75W85).

 

[Bror Jace]

Thanks Molakule. I'm thinking of the Honda MTF II or Amsoil MTF for my '06 Civic LX 4-dr. Supposedly the factory fill was MTF I.

I dumped the factory fluid after about 10,000 miles. I have a mix of Red Line MTL and the last of the SpecForm MTL-P (which worked great in my Nissan's 6-speed) in there now. This stuff was not a great fit for this application ... and was downright terrible in the winter until the tranny warmed up. I won't go through another winter with it.

Anyway, I thought I heard someone speculate that Honda MTF II was just a touch thinner than the original Honda MTF ... but would like some lab test or printed material to back that up.

 

[Mr Nice]

I am very happy with the Amsoil MTF in our 2007 Civic EX

I drained the factory fluid at 48K miles and its quite smoother verses the 'green label' Honda fluid.

 

[Bror Jace]

LT4 Vette, is the green label the new or old Honda MTF?

 

[Mr Nice]

The green label is the new formula of Honda MTF.
