WRX TR690 CVT Drain and Fill.

This was my second drain and fill on my car. I have helped numerous friends in NYC do it as well and guided a number of you via messenger. First time I drained about 6 quarts. This time was between 5-6. I usually have 8 quarts ready just in case. As you all know I have switched to Amsoil synthetic CVT fluid and have used it for a few years now. I am very happy with it and even more happy with seeing how it held up since the first drain and fill. I purchased four 1 quart bottles and one 1 Gallon jug (about 4 Quarts). I first used the Gallon jug and added more with each bottle depending on the amount required. As I drained the CVT fluid I was able to see it was still nice and golden. Some had much darker and even a bit milky cvt fluid come out. If you are using a black container, pour some fluid on a white towel or paper towel to assess the color - or even a bit into a clear plastic container. If it was so black and milky you know it was for sure a good idea to change the fluid. Up to five drain and fills can be done in a short period of time to get rid of most of the old fluid, especially if it was very dark and milky. Once you assess the condition of the fluid, then consider doing another drain and fill in the near future - maybe a few weeks or a few months. I waited a bit longer as my fluid looked very good the first time around - imo this was mostly due to adding a cvt cooler early in the life of my car. My cvt was already up to temp once I arrived at my friends shop (95-113F). I also monitored it during the procedure via my obdlink MX plus and active obd app on my android phone - you can do it on the Cobb AP as well. After the CVT fluid change there is a slight but noticeable butt dyno improvement to how the cvt behaves imo. I feel the amsoil fluid does a better job in allowing the chain to do its job. My friends have reported this as well with other cvt fluids in Japan compared to oem "orange" high torque CVT fluid. I have attached photos with arrows to indicate what is what. I am also attaching the photos from my diff fluid change (you can find the whole procedure in the main group of posts on my thread here. You do not want to add CVT fluid into your diff or vice versa. Your car will not be happy with you. So take your time! Always feel free to reach out to me here or on facebook

General procedure:
1. Open CVT fill plug (Some do this as first step in case they have a hard time opening it after draining cvt fluid)
2. Open Drain plug to drain CVT Fluid - usually about 5-6 quarts will drain (Best into a measuring container to assess amount drained)
3. Close Drain Plug
4. Start to fill CVTF via main fill plug (I return mostly the same amount that I drained)
5. Temporarily tighten fill plug
6. Idle engine to raise CVTF temp to 95-113F (35-45C)
7. Operate Lever in P-R-N-D and D-N-R-P to circulate CVTF while engine is idling
8. Add more CVT fluid until starts to drip out of the main fill plug
9. Close Fill Plug

Tightening Torque 50N-m (5.1 kgf-m, 36.9 fl-lb)
