Replaced my clutch and throw out bearing, put the car back together and went to bleed the clutch. There is absolutely no pedal or pressure and it's internally leaking. Did I miss something or do I have to take the vehicle apart and get into the transaxle again? Was hoping for a leak in the line or a reason why it may be doing it?

Good afternoon,

Did you replace the clutch slave or the throw-out bearing?

I attached the bleeding process below for you to follow.

If it does not create a pedal, you may have a failed clutch master cylinder.

Hydraulic Clutch Bleeding

Notice: Do not reuse the fluid that has been bled from a system in order to fill the clutch master cylinder reservoir for the following reasons:

1. The fluid may be aerated
2. The fluid may be contaminated
3. The fluid may contain too much moisture

Important: Maintain the fluid level in the clutch reservoir to the top step with GM P/N 12345347, or equivalent.

1. Clean dirt and grease from the cap in order to ensure that no foreign substances enter the system.
2. Attach a hose to the bleeder screw on the clutch actuator assembly. Submerge the other end of the hose in a container of Hydraulic Clutch Fluid GM P/N 12345347, or equivalent.
3. Depress the clutch pedal slowly and hold.
4. Loosen the bleeder screw to purge air.
5. Tighten the bleeder screw to 2 Nm (18 inch lbs.).
6. Repeat steps 3 - 5 until air is purged.
7. Fill the reservoir to the top step with GM P/N 12345347, or equivalent.
8. Repeat the bleeding procedure if necessary.
