Default Lost clutch after trans install

Today I was driving my car back home from the shop where I just had the transmission rebuilt and installed with a new ls7 clutch with a new Ram aluminum flywheel, new updated GM slave and a new master from Orielly Auto Parts. I was about to go from 4th to 5th and I pushed in the clutch and the pedal felt like it popped as if a hose popped off and lost all preasure and then just layed on the floor. I tried to call the shop but they had already closed and left. I know they were do a lot of bleeding of the system having some trouble while I was waiting for them to finish. Does anyone have any ideas of what may be the problem? Thank you in advance for any ideas and replies.

What you described sounds like the master blew an internal seal. If there's clutch fluid draining out the bell housing I'd say you blew a slave seal. Master more likely

Does the LS7 clutch require more pressure than the LS6 clutch and maybe that's why the master failed? I think I'm just going to order the Tick today

you are asking us whats wrong with your car but you need to look under it and determine if the fluid loss is coming out the bottom of bellhousing or look at the pedal where MC is and see if there is a sign of fluid leak

either way you have failing hydraulics, you just need to "look" and determine where....IMHO before you go out buying parts you think are bad.

If MC is bad that can be replaced without pulling tranny...but if the slave puked, the tranny needs to come out...

When the pedal lost pressure I was on the highway and coasted to the next exit so when I looked under the car it was dry the and I couldn't really see the bell housing with exhaust in the way and the car sitting low. I look up and around the pedal and the floorboard and it was dry. Now Im back at work and almost 500 miles away from my car. Thank you for your input. Ill have to wait till I go home again and look at it closer
