About to bleed my ZF S6-40. Any advice? - ZR-1 Net Registry Forums

My 6th speed grinded twice in a row yesterday morning, then never grinded again. However, I didn't like that. Car is now stored until transmission fluid and clutch fluid are changed.

So I just bought 700ml of Valvoline SynPower Dot 4 brake fluid.

Do I have enough? Is my process alright?

1. Disconnect battery.
2. Remove ECM (slide it off or remove nuts, just use easier way).
3. I will see a reservoir for brake fluid, and one for clutch fluid (is it clearly indicated which one is which one?).
4. I will ask somebody to stroke the clutch pedal several times, then keep it pushed to 100%.
5. I will crawl under the car which WON'T be perfectly level unfortunately (is it that important to have it level?) and I'll find that clutch bleeding screw (where is it?). First time I will remove this screw, I will wrap it with Teflon 5-6 times.
6. Repeat process 4-5 to get rid of that old fluid as much as I can. I won't let it go lower than LOW in the master cylinder.
7. Fill with new brake fluid.
8. Repeat process 4-5 until there's no more air in the system and until there's only new fluid.
