probably a valve body issue. i had the same thing happen to me but in 3rd gear. turned out the valve body had separated because two bolts came out of it and it was loosing pressure.

I would pull the pan and check the valve body also

As noted above, drop the pan and make sure the vb attaching bolts are tight.

Also, the 1-2 shift valve can stick and cause this. It can be removed, the bore cleaned, etc. I had some success with doing this once.

I need to check, but I think a C4 has second gear applied by the servo applying the intermediate band. If the servo apply piston seals die, it wont apply. If it gets out of adjustment, it could cause this. Check to see if the adjustment bolt is tight and the locknut is still there.

Being a manual reverse v.b. it probably wont't utilize any shift valves as it no longer needs to shift automatically. 2nd is controlled by a servo applying the intermediate band. The fact that you never get 2nd (as opposed to getting second but it slips) makes me think shifter adjustment or maybe the anchor on the band ripped off.
