So I finally got to chance my transmission fluid with the AMSOIL MTF this weekend. Just to note, that these impression are based purely on the shift feel. In no way am I qualified to comment on the quality of the fluid or if AMSOIL MTF is better than fluid A or B.

This is the 4th transmission fluid that I have tried in about 2 years time. I have used OEM HONDA fluid, GM Syncromesh Friction Modified (GMSMFM), Redline MT-90, and now AMSOIL MTF.

I bought the s2000 about 2yrs ago and the car had about 25,000 miles on it. The shift feel of the car was nice but a little nochy. The first non-oem fluid that I tried was the GMSMFM, in the month of November where the weather gets down to about 60 degrees F here in california.

This fluid made the shifting extremely smooth, even in the colder months. The only problem with the GMSMFM was that smooth shifting only last about 3 months for me (about 3-4000 miles).

When spring rolled around and I started track my car more often I decided to try the Redline MT-90 transmission fluid. On the track the shifting feel very smooth but never quite as smooth as the GMSMFM. I did do one track day with the GMSMFM but that was when the magic smoothness of the shifting was already gone.

The negatives of the Redline MT-90 fluid is it is pretty nochy when cold. It takes extra effort to put the car into gear in the morning when the fluid has yet to warm up. In my experience it also take a while for the fluid to reach the temperature where the nochiness disappears.

With winter upon us here in california I decided to give AMSOIL MTF a try. I was tired of waiting for the mt-90 to warm up, which would take a bit with the cold weather. In terms of shift feel when cold, I would say it is not quite as smooth as the GMSMFM, but definately smoother than the mt-90.

Hopefully I will be able to get back on the track soon, and see how the AMSOIL MTF performs there.

Just a question for all you automotive fluid gurus out there. How do you know when it is time to change the transmission fluid, or how would I identify that a certain transmission fluid is not up to par when on the track?

Again these are just my personal observation and in no way should they be considered advice of a professional which I am not.

I've been running Amsoil in my 04 trans for about a month now.

I do not notice any difference between it and Honda MTF.

I have not tried redline, that will be next.

Read above ... lots of input. Amsoil MTF is good to go from well sub-zero to desert heat. DC is somewhere in between so it'll work like a champ.
