Same fluid as the brakes, in fact same reservoir unless you have an early machine with the three separate reservoirs. The bleed fitting is under the oil tank, in a black plastic "L" fitting on top of the gearbox unless you have one of the few with an external slave cylinder which is on the lower left of the gearbox.

I removed the coil to make bleeding easier, but it's probably not essential to do so.

Nothing special about the bleed process-just like brakes. Two people with one running the pedal, or 1 person with a vacuum bleeder. Because the master is below the slave, it bleeds pretty easily.

Are you sure the issue is your master?
