Thanks. What has to happen on this style is you have to remove the line from where it connects on side of trans. you need a special release tool to do this. You can ask most any parts store for the trans line quick connect release tool. Once line is unhooked, you then have to follow the procedue below by pushing in on the check ball at the end of the line you unhooked. There is no other way to bleed the system. You may? be able to use a couple small screwdriver to try and get that white sleeve to slide to unlock line but.. dont mess up the sleave and then get a tool if this does not work

1. Using coupling disconnect tool No. T88T-70522-A or equivalent, disconnect hydraulic coupling at transmission by sliding white plastic sleeve toward clutch slave cylinder while tugging on tube.
2. Clean area around clutch master cylinder reservoir cap, then remove cap and fill to step with suitable DOT 3 brake fluid.
3. Using screwdriver or equivalent tool, depress internal mechanism of male coupling to open valve. Then, while holding valve open, depress clutch pedal fully and hold.
4. Remove screwdriver from coupling to close valve, then release clutch pedal. Clutch master cylinder must be kept full at all times to prevent air from entering system.
5. Refill reservoir to step, then operate valve and clutch pedal as described above. Reservoir may again need to be filled.
6. Close reservoir, then reconnect coupling to clutch slave cylinder. When coupling is secured, cycle clutch pedal as quickly as possible through 5 to 10 strokes.
7. Wait 1 to 3 minutes, then repeat clutch pedal cycling 3 more times with 1 to 3 minutes between each set of 5 to 10 strokes.
8. Loosen clutch slave cylinder bleed screw, then depress and hold clutch pedal while torquing bleed screw to 2.2-3.7 ft lbs .
9. Refill reservoir to step, then check clutch operation. If clutch does not release fully, indicating air has remained in system, repeat procedure.

Hello, I was helping you on this post and now you are asking about bleeding the master? you started another post. Bleeding the master is the same as bleeding the slave or system. I sent this info to you. Bleeding is usually not the problem if you have a clutch problem. If air got in. a part is bad. Aitr cant get in al by itself. LMk thanks
