so i want to switch out the tranny fluid from my car in the next couple of weeks but would like to know what do you guys recommend for track use.


i have been using the oem mtf ever since i bought the car and tracked with that fluid aswell but would like to know if there is something maybe better.


one person told me to mix the oem and Synchromesh half and half and that works good for tracking but i wonder if this a good idea?



any other opinions ?


would appreciate the help

by the way i do not drive this in the street only track toy.

i have another daily

 

I would avoid mixing brands. Just go with Amsoil MTL, it will give you a bit more protection in higher temp conditions over the Honda and Synchromesh IMO. Though there is nothing wrong with either the Honda or Synchromesh on their own, I just found that the Amsoil works better than either one. The Amsoil gives a bit more viscosity protection which you want at the track. There are other fluids made by Red Line that have even higher viscosity but I've never used them on the S2000, they may work in higher temp/track use conditions, but perhaps not as well in cooler street driving conditions.

 

Torco MTF was recommended by a reputable Honda trans builder. Its been working better than Honda MTF for me, in terms of shifting feel per number of track days. I don't drive it after it snows, but cold fall mornings do make it feel notchy. The cold weather performance is not as good as Honda MTF.

 

Any time you move up in weight the cold weather performance will suffer. But who will take a car out and beat on it when cold(the car not the outside temp)? Once the oil, water, trans and diff warms up you can feel how well the thicker trans fluid feels and works.

thanks for the opinions i want to do maybe a little thicker oil since my car is already at 85k miles . and ima be tracking a little more this coming year.

 

Amsoil will get you a bit more viscosity than the Honda MTF2, and surprisingly it works damn well in cold temps. A few times I've driven it in near 32 degree F weather and it shifts perfectly from the first shift, I don't even have to baby it waiting for warm-up. You generally do sacrifice some cold temp operation when moving to a thicker fluid, but the synthetic base of Amsoil help with cold temp flow.

 

Redline MT-90.

 

With the Redline you can mix in any amount any of the three, MTL, MT85 or MT90. You can start out on the light side and move up thicker a little at a time till you get what's right for your car at your track.
