You may have watched this already, but I thought I'd post it just in case. Before I rebuilt mine I watched nearly every video of a C4 I could find on you tube, and I googled and read so many posts from other forums it was crazy. Any way here's the video of the air checks.

Almost sounds like the wrong VB gasket was used or a check ball was left out.

That is assuming you do indeed have vacuum at the modulator and you didn't leave out the pin.

Did you soak the bands in ATF before installing? If not its probably going to act up for a while.

Without looking at my book I can't remember right now if a band is activated to produce 3rd. If so could have a bad servo and band isn't applying.

Air check was good on all but one port for reverse/high clutch.I took the pump out and realized i had put the wrong size rings on the pump stator. In the process i was successful in breaking one of the rings that I needed,so I'm in the process of trying to find one.

Glad you got this fixed. After a few tries I got my C4 running solid.

I know I'm late on this, but glad you got it running it!!

Too bad you had to pull it back out though.

I broke one of those rings the first time time trying to put them on too, I broke the teeny tiny part that catches and locks the ring. Now I know how to hook and unhook them, in case if I ever do another one. LOL
