List of transmission fluids and their viscosities

***Ruthless909*** · 03-04-2007, 06:13 AM

Lower numbers = thinner fluid = better shifting when cold = worse protection when really hot

RP Synchromax (syn) = 7.7
Torco MTF (syn) 8.35
GM Synchromesh/BG Synchroshift (dino) = 9.1
SF Synchroglide (syn) = 9.5
Amsoil MTF (syn) = 9.6
Neo MTF (syn) = 10.0
RL MTL (syn) = 10.6
Honda MTF (dino) =11.26
SF MTL-P (syn) = 11.5
Torco RTF (syn) = 14.33
SF MTL-R (syn) = 14.7
Motul Gear 300 (syn) = 15.2
Mobil (syn) = 15.2
RL MT-90 (syn) = 15.6

I got this info from ephatch.... Is this information right?? For instance If I would to change my trans oil to amsoil .... Will I have real bad protection when really hot??

need confirmation.

get a tranny cooler and try it out

Help anyone....

viscosity has little to do with high temperature protection in modern lubricants. Remember most Hondas now run 5w-20 motor oil and I don't hear about a bunch of them blowing up. Viscosity will have an effect on how your shifter feels, however. but I wouldn't worry about protection, especially when using a synthetic.

GM Synchromesh/BG Synchroshift (dino) = 9.1

they use this on there corvettes. you think that would be a good idea.?

my current Civic is an automatic, but I have always used RedLine MTL is my manual gearboxes with great results. It worked fine in my 2005 TL so it is fine in Honda applications.
