hello

i have ford focus sedan year model 2005 .1600cc automatic transmission.

i have the following problem:

after driving for some time especially in urban driving

when i move the gear stick to PARK mode:

1. the transmission warning led turns on (yellow led)

2. then when i move to drive mode i feel a "cick/blow" coming from the gear-box.

3. but when i start driving the led turns instantly off.

4. never had led turns on while driving only when in PARK.

5. also after switching engine off for about 2-3 hours the led does not turns on.

any idea what could be the problem (solenoid only or major problem in gear box)

thanks .
