Need help with Turbo 400 Trans

    I have a '78 C-30 with a turbo 400 that was rebuilt about 4,000 miles ago. I don't use it very hard. Just recently it started acting up. This is what I've noticed:

    1. When cold, everything works fine
    2. Once warmed up, it starts to slip and shudder in drive from a standing start
    3. Once moving, it seems ok, but I suspect that if it was loaded heavily it would slip then also.
    4. It always works fine in reverse.

    Any ideas what might be wrong? Any help would be appreciated.
