The two tests I know of -
1. Check voltage to the solenoid to see if its getting 12v
2. Check resistance of the solenoid - I forgot what its supposed to be
although the information is buried in the archives. But if the solenoid is
bad, it is likeliest in the solenoid coil so the circuit will not show any
continuity if its bad.
Both tests should be quick and easy, except for perhaps lying under the car
and undoing the wire between solenoid and switch on the transmission to
check voltage and resistance - its a somewhat tight fit for the hand to get
in and out.
