Opel Vectra Has A Flashing S Light

My problem: my automatic transmission didn't automatic change it is order. I mean when I start to move the car, I Put it on (D) but the car too heavy to move, so I put it on (1) then to (2) then (3) then to (D) then it move smoothly and with high speed. That mean when I put it on (D) it doesn't change the order to (1) Automatically to start move the car. Then to 2 and so on.

Also the () sign (lamp) on the front panel of the car is flashing. When I push the () button on the hand of the automatic transmission the () on the front panel doesn't switching ON or OFF and still flashing. Please help me and guide me to follow and to check where to find the error or the fault. As I think it is electrical fault not mechanical.

Some where in the sensors, but which one????? Which sensor give the signal to control box to make the automatic transmission system to change it is order automatically? Really I don't have any idea or where to look but I have my technical service man which I want to help him with your answer.

Thank you in advance, I'm waiting your reply.

A. When the A/T control unit senses an abnormality in the input or output systems, the indicator light in the gauge assembly will blink at equal intervals and the LED display on the A/T control unit will blink a problem code when the ignition key is turned on. However, when the Service Check Connector (located to the lower right of the glove compartment) is shorted with a jumper wire, the indicator light will also blink the problem code when the ignition switch is turned on.

When the indicator light has been reported on, short the two terminals of the Service Check Connector together or pull the passenger's side carpet down from under the dashboard. Then turn on the ignition switch and observe either the indicator light or the A/T control unit LED display.

Problem codes 1 through 9 are indicated by individual short blinks, Problem codes 10 through 15 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code.

Some PGM-FI problems will also make the indicator light come on. After repairing the PGM-FI system, disconnect the Back Up fuse (7.5 amp) in the under-hood relay box for more than 10 seconds to reset the A/T control unit memory.

There are 15 possible codes, 1 through 15, and once we know what the code is, we can find out what is wrong.
