Perhaps the first replacement solenoid was not new. It may have been on its
last legs.

There could also be a problem in the transmission control conputer. Solenoids
need a surge of current when first turned on to pull it in and then considerably
less to remain activated. Maybe the control unit is not reducing the current
flow through the solenoid after that first inrush thereby cooking it. That
might cause it to fail prematurely.

Have you checked the transmission computer for error signals? When the ignition
is on, a light-emitting diode may flash on the computer module. The number of
flashes, if any, indicates which problem the computer is experiencing. I don't
know where that is on a '96 Civic - probably under the carpet under the
passenger's feet.
