Question Clutch/Tranny - Problem/Question

Hiya All -
The Tranny is in, clutch has been replaced, all bolts are secured, and amazingly, I have no extra bolts...lol The problem is that I cannot shift into any gear when the car is running. The clutch pedal feels a bit spongy, but the fluid in the cylinder is fine. When the car is not running, I can shift into any gear.
Does anyone know what I did wrong while replacing my clutch? What would cause the inability to shift, even with the clutch fully depressed? The pedal itself is adjustable, and is adjusted to its maximum throw -
I thought about bleeding the clutch, but I don't think that is the answer because I lost no fluid when I changed the clutch....

Has anyone else had this problem?

Any Ideas?

Possible problems:

Cluch needs bled, shift fork not properly aligned, clutch disc in backwards, input shaft not lubed and throwout bearing sticking, pilot bearing bad or binding, pivot ball worn or broken.

The first is external, all the others require pulling the tranny again. Btw, most any tranny will shift with the engine off, regardless of clutch condition.

Thanks for your input, but the shift fork lines up perfectly, The clutch disc is in correctly, The pilot bearing and throwout bearing are brand new, and lubed accordingly, and the pivot ball was cleaned and checked before the tranny went in today....
Any other Ideas?

Maybe an internal leak in the hydraulics somewhere.

Maybe the clutch pedal was adjusted incorrectly. I've found that before I understood what was going on, adjusting the clutch pedal seemed anti-intuitive.

Here's something you might try. Jack up the rear tires and support the rearend. Shift into 1st, crank the engine until it fires up (in gear). Then depress the clutch, with your other foot on the brake a little. See if you can simulate a load on the rear wheels with the brakes applied somewhat to simulate driving down the road, and feel for the friction point in your clutch.

If there is a little change, the pedal is out of adjustment. If there is no change, it may be out of adjustment, or there could be a bigger problem. This is what I'd do because it takes very little time to set up, could tell you so much, and is a lot safer than attempting to drive without a working clutch.

Thanks for the ideas - I think I'll try try bleeding the clutch first, if that doesn't work, I'm gonna try Jeff's idea. If that doesn't work, well, Lets just one of those works - I really don't want to take that tranny back out!
