Given your username, I derive that you have a '91. If so, and if stock, your '91 has an internal slave which is a totally different animal from that discussed in this old thread. If you stick with the stock internal slave, then you will notice that a bleed line protrudes from the Bell housing, and this is where the answer to your question lies. The confusion may be that the external slave model years (94-95) are typically sold as a complete assembly that is pre-bled and filled. The internal slave set up such as yours requires to be bled manually via the fitting that protrudes from the bell housing. You may also consider upgrading your rig with the external slave set up.
