Trying to troubleshoot why my newly rebuilt trans will not shift out of
first.  Reverse and first work fine.  In "1" if I accelerate and then let
off the gas, the engine braking occurs.  If I'm in "2" or "D", and I
accelerate then let off the gas, it freewheels.  So something is trying to
happen at the point it shifts up from 1st.

Here is my question.  I have studied the manual schematics, and taken the
thing apart and back together, but still do not have a good understanding
of how power is transmitted in the various gears.  Planetary gear systems
are pretty cool, but can be difficult to visualize their various modes of
operation.  I wish I had a series of drawings of how the power flows
through the trans in the various gears.  I am assuming that the 2nd gear
brake band is utilized only for second gear operation.  Do any other
pistons operate to activate 2nd gear?

Any help/advice appreciated,
Edward
