so this weekend we tore the truck down and converted it from an allison to a zf-6. the conversion went suprisingly well except for the fact that my clutch wont release all the way. when i push my pedal down it goes down about a quarter of the way before any pressure starts then you push it to the floor then it starts to feel like the clutch pedal should. sometimes i can get it in 3 4 and 5 and it will sit there but not all the time.... Anybody have any suggestions?

Did you bleed the clutch? Most of the time that seems to cure it

Sounds like you have air in the system-- try to bleed it again.

I just went through this with my beater Ford Ranger--bled a quart of fluid through it. Made a pressure bleeder from an old cap-- no air came out. Finally the only way to get the air out -- I pulled the master cylinder piston out a little, while still connected to the reservoir. Some fluid came out and I slid the piston back in, then refilled the reservoir. Not easy, but that did fix it.

The cylinder sets an an angle and had a pocket of air trapped in cylinder piston.

yea we've tried bleeding it on a couple different tries and still no luck... is there a stronger/better slave and master cylinder that from the factory?
